Cause & Effect Diagram




Cause & Effect Diagram

The cause & effect diagram is the brainchild of Kaoru Ishikawa, who pioneered quality management processes in the Kawasaki shipyards, and in the process became one of the founding fathers of modern management. The cause and effect diagram is used to explore all the potential or real causes (or inputs) that result in a single effect (or output). Causes are arranged according to their level of importance or detail, resulting in a depiction of relationships and hierarchy of events. This can help you search for root causes, identify areas where there may be problems, and compare the relative importance of different causes.
Causes in a cause & effect diagram are frequently arranged into four major categories. While these categories can be anything, you will often see:
  • manpower, methods, materials, and machinery (recommended for manufacturing)
  • equipment, policies, procedures, and people (recommended for administration and service).
These guidelines can be helpful but should not be used if they limit the diagram or are inappropriate. The categories you use should suit your needs. At SkyMark, we often create the branches of the cause and effect tree from the titles of the affinity sets in a preceding affinity diagram.
The C&E diagram is also known as the fishbone diagram because it was drawn to resemble the skeleton of a fish, with the main causal categories drawn as "bones" attached to the spine of the fish, as shown below.
The fishbone diagram, as originally drawn by Kaoru Ishikawa, is the classic way of displaying root causes of an observed effect
Cause & effect diagrams can also be drawn as tree diagrams, resembling a tree turned on its side. From a single outcome or trunk, branches extend that represent major categories of inputs or causes that create that single outcome. These large branches then lead to smaller and smaller branches of causes all the way down to twigs at the ends. The tree structure has an advantage over the fishbone-style diagram. As a fishbone diagram becomes more and more complex, it becomes difficult to find and compare items that are the same distance from the effect because they are dispersed over the diagram. With the tree structure, all items on the same causal level are aligned vertically.
The cause and effect diagram can also be drawn with right angles, which makes it less tangled, and easier to see what layer of causality is being considered at any given time.

To successfully build a cause and effect diagram:

  1. Be sure everyone agrees on the effect or problem statement before beginning.
  2. Be succinct.
  3. For each node, think what could be its causes. Add them to the tree.
  4. Pursue each line of causality back to its root cause.
  5. Consider grafting relatively empty branches onto others.
  6. Consider splitting up overcrowded branches.
  7. Consider which root causes are most likely to merit further investigation.
Other uses for the Cause and Effect tool include the organization diagramming, parts hierarchies, project planning, tree diagrams, and the 5 Why's.

How Real is the Green Supply Chain?



How Real is the Green Supply Chain?

by Dan Gilmore 

I have held off writing about "the Green Supply Chain" and Sustainability for a long time, but here we go…As usual, I will probably get myself in a little trouble.. My "First Thoughts" on the subject – and what are to me the two key questions related to Green – are in this column. More over time.

Let's be clear upfront that in developed economies virtually 100% even of corporate executives, many environmentalists may be surprised to know, want a clean environment. All anyone has to do is visit Hilton Head Island, Yosemite National Park, or any of hundreds of other fantastic places and who could want anything but a wonderfully healthy ecosystem? The story is different in many developing economies, which is where we were 100 years ago.
Still, as with everything in life, there are trade-offs. We could outlaw cars tomorrow and get rid of a huge chunk of our carbon emissions, but of course only a few on the fringe would opt for that. And by the way, that might lead to a resurgence of horse-based transportation, which would have its own, shall we say, negative environmental impact (more on that theme in a bit). The point is that clearly not every Green decision is worth the trade-off.
Undoubtedly, in this environment, where Green is all the rage, it's hard for any company or individual to swim against the tide – and probably no one should. But I also get the sense right now that in many companies and circles if anyone was to actually suggest there are trade-offs to be considered, it might be a career-ending move, or make it appear you are some greedy, smog-loving cretin, which is nonsense.
Some points worth pondering:
  • It's no wonder many CEOs are at least publicly on board. When Fortune magazine named GE the world's most respected company a few years ago, it cited CEO Jeff Immelt's focus on Green as among the key factors. Other CEOs were watching, and would love to have themselves and their companies recognized in the same way.
  • It's clear to me at least that much of the corporate support for Green is as much for the potential to sell new products/technologi es as it is about saving the planet. As we recently reported, for example, a McKinsey survey found that 37% of manufacturing executives surveyed thought the risks and opportunities from the Green movement were roughly balanced for their firms, and another 21% thought the opportunities far outweighed the risks. So, you should take some of the Green rhetoric coming out of corporations with a grain of salt. (See Talk is Ahead of Action on Green Supply Chain, According to McKinsey Study.) GE may truly be interested in Green, but it's also happy to sell new, more expensive light bulbs and a new class of power generation equipment.
  • I don't like some of the coerciveness of the whole movement. I don't fully understand it, but there is something partly troublesome in the Carbon Disclosure Project's heavy hand in co-opting large investment banks to help pressure corporations to report carbon emissions, and sets in place a number of slippery slopes.
  • There are many obvious improvement areas that in retrospect should have been "No Brainers." Were transportation and packaging materials ever really so cheap that companies could afford to ship excess cube and pay for extra paper and plastic that were simply superfluous? I am confident that in the majority of cases, the return for the effort in improved packaging was always there, but was a treasure right in front of us that we just couldn't see. Nothing but positives here.
  • The interest in being Green obviously has been helped by the incredible rise in transportation and commodity costs. Whether you put a Green wrapper on it or not, taking out miles driven through network redesign, packaging changes, collaboration, etc., is just smart business right now.
  • We have to be very careful, however, to avoid knee-jerk decisions and the Law of Unintended Consequences. Easy example – certain cities banning plastic grocery bags in favor of paper, when it turns out - in total -the plastic is actually much more favorable to the environment. But there are many more examples. Most of us are aware, for instance, that the push for ethanol as a fuel has in part led to surging food prices worldwide, as demand for corn for energy purposes drove up the price for corn, led farmers to plant fewer soy beans, etc.  But it goes further than that. Farmers around the coast of Lake Erie in Ohio, for example, had been receiving some modest government incentive for leaving land fallow. Now, they find it more profitable to plant corn again. The result: the lake is being damaged by severe run off from the chemicals in the fertilizer that the farmers are now using again near estuaries.
To me, though, there are really two key questions.
First, will the consumer, or business customers, really pay more for the environmentally friendly product? I really haven't seen much data either way. One thing we absolutely know is that neither the consumer nor business will pay more for the "Made in the USA" product – but we think they will do so for the environmentally- friendly ones? Some segment, probably at the high end, likely would, but I am not sure how many beyond that, if offered a real choice. The implication of that, if it is accurate, is that Green improvements have to be at least cost neutral, and/or Green products must be mandated by government or Wal-Mart, Home Depot, etc.
Second, how will companies actually make Green decisions? My favorite example – what if there is a more environmentally- friendly industrial adhesive that will cost a couple of cents more a pound. Will a company buy that product instead of the regular adhesive? What if the raw material cost is the same, but manufacturing has to run the packaging line a bit slower because of slightly reduced performance?
The real issue is what framework will be put in place for making such decisions. Does the procurement manager have some guidelines in place that says you can increase supply chain costs under these circumstances or within these limits for a given level of Green improvement? How can any company manage these trade-off questions across potentially hundreds of decisions on a regular basis? Will it really be willing to increase supply chain costs to be more Green? And should the adhesive supplier put R&D into making the more Green product instead of reducing the cost of the current one?
I was at a recent conference and asked a new VP of Sustainability at a large consumer goods company these very questions. It was clear he wanted no part of an answer, and blew me off with some non-response about things will evolve. But that said a lot to me about the true state of affairs right now.
That's my perspective. As always, I am just trying to get at what's real.

Do You Have Great Job Designs?


Do You Have Great Job Designs?
Most organizations have job descriptions, but many fail to specify in those one or two page documents how time on the job should be spent. It is more often the case that expectations are listed along with regular job tasks, but no reference to the percent of time that should be used in these areas is provided. Why are time percentages necessary?
Time percentages are necessary for two reasons. First, time and money are the two main things we spend on the job each day. In turn, when we spend our time in areas where we don't need to, or in areas that don't give us that much performance improvement leverage, we are creating waste.
Second, most people do not do a very good job of tracking how they spend their time each day. This is especially true if you work in a crisis focused environment - as you get caught up in a crisis, your emotions overwhelm your mind's ability to keep track of time. Similarly, if you are intensely focused on performing a task, it is difficult to track the minutes and hours that go by.
Over the years, most organizations have invested a lot of time and money in defining how time is spent on the front lines. As an Industrial Engineer, I personally measured down to the tenth of a second how long it should take to do such work. On occasion I would be asked to take a similar look at a middle management level job, but this practice was much more the exception than the rule.
I believe that we have reached a point in the evolution of business where we have nickel and dimed the front lines to death. At the same time, we have largely ignored the time efficiencies of management, with this ignorance becoming greater the higher up you go in a given organization. What are we assuming here? Are we assuming that because we pay these people so much money, they should and do make sure that they are spending their time in the best way possible? Think about it!
If you aren't spending enough time with people and on projects, you can't improve. It's that simple. Do you need great job designs?
Do You Like Fighting Fires?
My business learnings have led me to realize that every person in an organization spends their time on two types of things - processes and projects. As you go higher up in a company, you will find that a greater percentage of job time is spent on projects - or at least it should be.
Managers spend a lot of time in meetings for example. A meeting is either project focused or process focused. Some meetings are training oriented, but in every case the training focuses in either on process improvement or personal development (which is a project). Do all of your managers know what percent of their time they spend in meetings? Are they working to make these significant time investments more value added?
A lot of managers and supervisors thrive on 'living in a crisis.' Their self esteem is largely rooted in solving problems. Fewer managers enjoy working on projects. Some do realize that true process improvement, which requires the implementation of one or more projects, helps eliminate the potential for crisis, but they just can't find the time to work on them. They're too busy fighting fires!
In order to move towards higher levels of performance, you have to shift your time expenditures from processes to projects over time. At first, the projects will be directed at putting out the fires for good. Once the majority of the fires are put out, the project focus can shift to benchmarking other high performers, developing skills, and defining and implementing innovative system changes. I think you see the potential dilemma however - if you can't put out the fires for good, you can't expect to go a whole lot faster.
Are You Hiring for Excellence?
If I had to pick one process that has the greatest effect on an organization, I would select the hiring process. A lot has been said about the need to shift cultures in order to reach higher levels of performance. While that is true, we often fail to realize that the hiring process, more than any other process, serves as the primary driver of culture, and in turn, organizational performance potential.
When an organization hires its first employee, it creates its culture - after that, it is all about shaping that culture. We would like to think that leadership, training, and meetings can serve as the main drivers of performance improvement, but if you really think about, the hiring process is what determines the fate of your business, school, or team.
This is particularly true in this day and age, when it is much more difficult to get rid of those problem employees that 'somebody' hired. Additionally, most supervisors will tell you that employee problems take up much, if not a majority, of their time on the job each day. The cost of a weak hiring process is both astronomical and long lasting.
Do you hire for excellence?
Some Simple Questions
Who makes more per hour, a front line employee or a manager? Does this wage rate increase or decrease as you move upwards on the organizational chart?
Who in your company measures their personal time use on an hour by hour basis, or has it measured by someone else? What are the reasons for measuring the low wage rate people to a high degree and only measuring the people that make a lot more money per hour only at times, if at all?
Would it help if you chose to make some changes in your time measurement practices?
These questions are important to consider if you desire to have a high performance workplace. You should also question the logic behind the two tables shown at the right if this is your goal. In high performance workplaces, people spend more time working with others than they do working alone. If you are going to be working more with others, shouldn't you all be holding yourselves to the same set of time monitoring and usage standards?
Would You Like Some Help?
Over the past 20 plus years, I have helped set up and manage job design systems in five different companies - both small and large - in the manufacturing and service arenas. This experience has helped me discover value added, simple ways to set up systems for measuring personal effectiveness and helping each person get more out of the time they invest at work each day. Failing to 'put out the fires for good' is the primary power restrictor for this power system - these tools help you both eliminate that barrier and move forward more rapidly towards higher levels of performance.
If you are interested in the job design systems and tools that I have to offer, send me an e-mail at kevin@greatsystems. com. Better yet, give some thought to working further with me to help you improve your job design system through my interactive job design improvement workshop. It's a one day experience that will change the way you do and measure work forever.
Keep improving! -- Kevin McManus, the Systems Guy

Time and Life, Bit by Bit

Time and Life, Bit by Bit

By Drew Vics

Looking out through my picture window during a recent winter storm, I felt like I was in a giant snow globe. Big, fluffy snowflakes were falling, covering everything with a nice wintry blanket. Ah, how nice. I love snow.... all two feet of it in my driveway!!
Now don't get me wrong, I really do love snow (send more!) but it does take its toll — my back was a bit sore, and it grew more difficult to keep my eyes open as the day carried on. I slept like a rock that night.
It could have been worse, I could have totally wiped myself out by trying to shovel it all at once. We do it all the time. Bite off more than we can chew, or grow impatient and try to rush through, or into things. We can apply this to other areas of life as well. If we rush through things we can end up suffering in the long run.
You know how I handled the snow? Bit by bit. Little by little. I went out at 7 am and shoveled the first 9 inches. Then my wife and I went out two more times that day to take care of the rest. I learned this "technique" from my father. When I was younger he always had me outside clearing the driveway with him, against my best (punk) judgement at the time. We'd go out at regular intervals to "keep ahead of it" as he said. Smart.
Now, how many times do we not think to "keep ahead" of things in our lives. I don't know about you, but I do it all the time. I want things done right away, I can't stand waiting. Lately, I've noticed my attitude changing a bit. I'm still impatient in some respects, but I'm more patient with myself. I'm the one who needs developing, and that takes time.
If you feel like you're getting nowhere, even wasting time, take heart. Life isn't meant to be lived in one day, or even a week. Life is development, learning and experiencing.
Don't waste life by worrying about time. Live life by using time. Bit by bit.

Perfectionism - The Dangerous Trap!




Perfectionism - The Dangerous Trap!
By Allie Ochs
 
Just when I have something figured out, along comes another how-to-article telling me how to be or do something better or even change my entire life. No matter where I turn, I am constantly reminded that I am not good enough in more ways than one. I am not smart enough, not rich enough, not slim enough, not efficient enough, not pretty enough, not powerful enough, not "with it" enough and probably "out of it" altogether.
 
That's me and it gets worse. In line with our education economy, yesterday's perfect diet is banned today and my car of the year was just recalled. My time-management is out of date and my writing achievements fade against the big authors. Yes, I am my own worst critic. Growing up with perfectionist parents didn't help either. It wasn't until their seventies, that my father could tolerate fingerprints on his freshly washed car and that my mother learned to enjoy a meal without matching table d?cor.
 
Perfectionism is driving us up the wall or around the bend and neither direction is desirable. No wonder half of the population is on Prozac and the other half copes on some other crutch. We live under constant pressure to be perfect and expect nothing less from others. Intensely glued to information that helps us conform to some perfect ideal, we learn less about ourselves. Detached from the core of who we are, we show up with fabricated selves to gain approval.
 
There is quite a difference between aiming for a successful life or relationship and trying to achieve perfection. Contrary to popular belief, perfection is not required to succeed in love and life. In fact, the perfectionism- trap has serious negative consequences:
 
We feel our accomplishments are never good enough
We don't achieve personal satisfaction
We value people based on their achievements
We believe doing our best doesn't cut it
We take mistakes personally and hesitate to try again
We are afraid to show our flaws
We are vulnerable to rejection
We do what we should, not what we want
We set impossible to reach goals
We are hard on others and ourselves
We expect perfection of others
We develop a obsession with perfectionism
We feel we never measure up
We fear failure in relationships and have difficulties being intimate
We don't pursue a relationship out of fear it might not be perfect
We become critical of our partners
 
To sum it up, we believe that unless we are perfect success and love will evade us. The biggest cost of perfectionism is our neglect of the humble core within and our failure to claim a life in alignment with our true self. Instead of focussing on our qualities and all that is right with us, we are busy fixing everything seemingly imperfect. Driven to live up to the perfect ideal we become pretentious, self-promoting, critical human beings. Because of our focus on achieving goals, we never enjoy the journey of getting there. As a result we lose the irreplaceable moments of relating to people and doing things.
 
Webster defines perfectionism as "a disposition, which regards anything short of perfect as unacceptable" . The torment for perfectionists is that they never find anything perfect, simply because perfection does not exist. Instead they suffer from social and personal anxiety and strained relationships. To find peace, accept ourselves and nurture the best in us, we have to overcome perfectionism and:
 
·Use our mistakes as opportunities for growth
·Set goals in line with who we are and what we want
·Accept ourselves as human beings with flaws
·Give a little less than 100% and still experience success
·Enjoy the journey instead of just focussing on the goal
·Recognize that anxiety arises when we set unrealistic goals
·Understand that we get more done and feel better about ourselves if we don't strive for perfection.
·Give up the irrational belief that relationships must be perfect ·Stop second guessing ourselves
·Be compassionate with ourselves and our partners
 
Thousands of people give less than 100% to a goal, but 100% to the journey and succeed. Everyday people don't give all they've got, but still get done what they need to. If we try to give 100 % to everything we do, we never get enough done. Perfectionists operate on the assumption that unless they can give 100 % to a task, they won't even start. As a result, they become occupied with trivial details and put off tasks until they can make a 100% effort. Perfectionists tend to be procrastinators with endless to-do lists and dreams put on hold until "some day."
 
When it comes to relationships, perfectionists don't do that well either.. Single perfectionists keep on dating without making a choice, thinking someone more perfect will be around the corner. When they are in a relationship, the fear that it might not be perfect, keeps their relationships from progressing. Even when they finally settle with a partner, second-guessing their choice and being critical of their partner ensures frustrating relationships. Compromise in love as well as in life is difficult for them. Perfectionists pay a high price for the misguided belief that choosing the right love partner will guarantee a perfect relationship.
 
The entire perfectionist- trap becomes a vicious cycle in life and love. The more we attempt to be perfect in every area, the more anxious we get. This anxiety is coupled with a feeling of always falling short or behind. Consequently we concentrate on what is wrong with us or what we didn't do. While doing our very best is admirable, more often than not, doing a good job is enough. The truth is that we are always half-cooked human beings in transition. Nobody will love us any more just because we are more perfect. We are being loved for the passion and spirit we bring to the table as genuine human beings.

Linking Customer Behavior to E-Commerce Strategy




Linking Customer Behavior to E-Commerce Strategy

Published: December 06, 2000 in Knowledge@Emory

In an article on Nov.13, 2000, in the Financial Times' Mastering Management series, Wharton operations and information management professor Eric Clemons and Wharton Ph.D. student Michael Row note the critical importance of consumer behavior when it comes to establishing a web retailing strategy. Below, the researchers look at the type of relationship between buyer and seller, the scope of goods and services linking buyer and seller, and the four competitive landscapes that result from the interplay of these forces.

Consumer behavior should be the principal determinant of corporate e-commerce strategy. While technology will improve, consumer loyalty, for example, is likely to differ significantly between, say, online booksellers and providers of financial services. Two factors seem critical in predicting behavior and determining an appropriate e-commerce strategy.

First, what is the duration of the relationship between buyer and seller? That is, does the buyer have a relationship with a favorite seller, in which they come to learn about each other, or does the buyer search for a different electronic vendor for each interaction? The former suggests an opportunity for tuning offerings; the latter precludes stable relationships.

Second, what is the scope of goods and services linking buyer and seller? Does the consumer purchase a single good or service, or a bundle of related goods and services? The former suggests the consumer searches for the provider of the best individual goods and services, while the latter suggests a search for the best provider of a collection of goods and services.

Combining these indicates that different companies, in different industries, will find themselves in one or more of four competitive landscapes.

Consumers buying products that can be described as opportunistic spot purchases exhibit no loyalty; each purchase may be from a different vendor and there is no one-stop shopping. They may buy a ticket from British Airways one day and United the next, and book their hotels separately.

Opportunistic store markets occur when consumers exhibit no loyalty or relationship continuity to brands or stores. Unlike the spot market, however, they do use intermediaries to construct bundles of goods. They may shop at Sainsbury one day and Tesco another; they may use Amazon.com one day and Buy.com another.

Consumers buying in categories that may be described as loyal links exhibit continuity when choosing vendors and service providers, but have no desire to have bundles prepared for them. They may never leave home without their American Express cards, but see no reason for their card issuer to be their insurance provider or financial planner.

Finally, consumers buying in categories that may be described as loyal chains will have preferred providers. Additionally, they will count on these providers for a range of tightly coupled offerings. They may work with a financial consultant at Merrill Lynch who helps pick stocks, reminds them to draft a will and arranges guardians for their children, helps find a lawyer and reviews their insurance. The integrated service is so effective they seldom consider switching providers or taking the time to provide these things for themselves.

Each of these environments has a different competitive feel, and requires a different strategy and use of different assets. This is as true in the physical world, where companies understand it pretty well, as it is in the dot-com world, where companies are struggling to develop profitable strategies..

Note that no e-commerce company [operates in just one environment] . There are, for instance, loyal link customers and companies may pursue them with loyal link strategies, but in reality some customers may use a web site for spot purchases and others may show great loyalty. The challenge for companies is to guide the consumer to the behavior matching the company's strategy; where this is not possible, companies should match the strategy to the customer's behavior. The approach given here may help managers discover the forces that determine their best strategy.

Opportunistic spot

Competition in opportunistic spot markets is based on price, since there is little loyalty to influence consumers' decisions.. This brutal competition is exacerbated by nearly perfect web-based information. Thus, for standardized products such the latest Harry Potter book, we observe both Amazon.com and BN.com selling at cost price. Where possible, companies try to soften competition by creating quality differences and ensuring consumers are aware of them. However, this branding must be based on real differences, since with nearly perfect information it is difficult to deceive consumers. There is a limited role for intermediaries. They may reduce risk in conducting transactions, but in most instances, consumers will buy from a set of trusted, well-known manufacturers and service providers.

The Internet will be used for supply chain management and logistics to ensure the lowest cost structure and the lowest prices. It will also support access to information on consumers, both current and potential new accounts, to allow the most accurate setting of prices where differential pricing is required. That means no applicant for insurance can be undercharged based on inaccurate risk assessment and no applicant for a credit card can be given too good a deal. In a market where no one can be overcharged without losing the account, there is little margin for error and little opportunity to recover from under-charging anyone. The ability to predict the profitability of a new customer, and so to determine a price to offer, is called predictive pricing.

It is essential to recognize consumers exhibiting opportunistic spot market behavior and to develop an appropriate marketing and pricing strategy. For example, in markets that exhibit this behavior, buying market share is unwise since it can be acquired only temporarily; when prices are raised to cover losses, customers will flee. Similarly, a policy of offering selected items below cost as loss leaders to attract traffic will be unwise, because consumers may easily purchase loss leaders from one site and the rest of their items elsewhere. Only time will tell whether the market for books, CDs or DVDs exhibits this behavior, so it is too early to assess the validity of Amazon.com's customer acquisition strategy or the promotional items of other web retailers.

Opportunistic store

In the absence of consumer loyalty, competition in opportunistic store markets again is based on price; however, it is the pricing of bundles rather than individual items that attracts consumers. Unlike spot markets, there are opportunities for intermediaries to add value, through logistical savings (shipping a box of books), or through assembly or integration (selling a package tour or designing a digital imaging platform where camera, printer and computer work together).

In this scenario, intermediaries enjoy power over manufacturers because consumers select bundles with little attention to components. Thus, when filling an order for paper towels, a grocer will use the product with the highest margins. This pursuit of margins, in the absence of brand loyalty from customers, shifts economic power to intermediaries.

Manufacturers will attempt to use the web for branding, to create consumer awareness of product differences and to weaken intermediaries' power. While it is dangerous to antagonize the existing channel in the opportunistic store scenario by trying to sell directly, branding offers manufacturers the ability to counter some of the power of intermediaries. As in the spot markets, manufacturers will also use the Internet to improve efficiency. Intermediaries will use the Internet to create branding for their web stores, so weakening price competition. They will use customer information, as manufacturers did in spot markets, for predictive pricing.

As in spot markets, no consumer can consistently be overcharged, so it is difficult to recover from undercharging anyone. While loss leaders can work in these markets, since a customer may fill a basket or obtain a bundle of services, there is little loyalty to assure repeat business; thus, as in spot markets, buying market share is risky since there is no assurance that initial losses can be recouped by overcharging for later purchases.

Of course there may be reasons to buy share in a "scale-intensive" industry where volume is needed to bring down unit costs. Indeed, some aspects of online retailing, such as grocery shopping, may be extremely scale-intensive, which could initially appear to justify buying share. However, without customer loyalty, the danger is that capital will be spent more on training users to accept online shopping and less on training users to accept your online shop.

Loyal Link

Competition in loyal link markets is based on retaining the best customers through a careful blend of service and pricing. For the customer, relationship value and pricing improve over time. For example, anecdotal evidence suggests online PC seller Dell has succeeded in creating loyal link behavior in customers, many of whom have bought several generations of computer from Dell.

In fact, no incumbent should ever lose desirable business to an attacker. If a less well-informed competitor were to attempt to persuade a loyal customer to transfer his or her business, the current supplier could decide whether or not to match the new offer. If the current supplier, with its detailed knowledge, were to choose not to match the new offer, odds are that the new supplier is making an offer that is too low. Successful attempts to get customers to switch in loyal link markets probably represent pricing mistakes by the attacker. Relationship pricing and value work to soften pure price competition in loyal link markets.

Buying market share will work under certain conditions, since it is possible to learn enough to price effectively. However, buying market share is ineffective without loyalty, as online brokerage firms are discovering; so it is critical to assess whether the company is operating in an opportunistic spot or loyal link market.

Using loss leaders in a link market will be unrewarding; offering online banking below cost to gain credit card business is unlikely to succeed in a link market, where customers will pick the best hotel and the best air service, or the best online banking and the best credit offers, independently.

Systems will be used for branding and attracting customers and to support relationship pricing and relationship service to keep the best accounts. These markets may appear to have only a limited role for intermediaries; however, intermediaries enjoy an advantage in controlling customer information and may end up owning customer relationships.

Loyal Chain

Competition in loyal chain markets, as in loyal link markets, is based on attracting and retaining the best customers and, as in loyal link, relationship value and relationship pricing improve over time. However, in chain markets, which are composed of a tightly coupled set of links, pricing to individual customers and the value they receive are determined by a bundle of goods and services.

Taking the earlier example of the digital-imaging platform, it may not be necessary to replace all components when upgrading. However, if buying a higher-resolution camera and a faster laptop, it is helpful to determine if the new computer and the old printer and are compatible, otherwise the customer may experience an unpleasant surprise if picking and choosing components in a spot or link fashion. If the previous chain supplier is used to update the components, unpleasant surprises are likely to be avoided, since his vendor can be relied upon to provide components that are compatible with those bought before. Evidence suggests Amazon has succeeded in encouraging a degree of loyal chain behavior from its best customers, who value the book recommendations made to repeat buyers.

Loyal chain markets represent a power shift from producers to intermediaries. Online intermediaries can reconfigure the virtual store to show loyal purchasers the brands they wish to see; customers without a preference can be shown brands that earn the highest margins. Indeed, it is a small step from this relationship- based presentation to demanding rebates from manufacturers to ensure that their offerings will be shown to customers with no brand preference. While physical stores charge a fee for preferred locations such as displays near checkouts, they cannot reconfigure the store for each customer.

This shift in online power greatly increases the importance of branding for manufacturers, because a powerful brand is the best counter to pressure from retailers. It also suggests that, to the extent permitted by legislators, manufacturers should form consortia for web retailing. This would avoid loss of control to retailers with significant information advantage. However, a broad consortium is needed since online markets reward scope and breadth.

Intermediaries may effectively buy market share through pricing low, enabling them to pursue informed relationship pricing over time. Likewise, they may use loss leaders to increase traffic through their web site, selling other items to consumers interested in a complete bundle.

Systems play many roles in chain markets. Intermediaries will use them for branding, to attract customers and for informed relationship pricing and service. Likewise, manufacturers will use the Internet for branding, so limiting price pressure from online retailers. However, efficient markets still place significant price pressure on retailers, assuring the role of systems for logistics and other forms of cost control. Likewise, manufacturers and service providers will use the web for their own cost control.

Conclusions

Three observations are true across all four competitive landscapes:

  • Only differences between brands, and consumer awareness of them, can blunt pure price competition in an efficient market.
  • Cost control is important: efficient access to information makes it almost impossible to overcharge.
  • As online information makes markets more efficient, predictive pricing will be used in spot and store markets, and relationship pricing in link and chain markets. Pricing strategies will be limited by adverse publicity that companies receive from charging different prices for the same goods.

Other conclusions follow from these:

  • The role of buying market share will vary. In opportunistic markets, buyers will leave when you raise prices.

Similarly, the role of loss leaders will vary. In spot and link markets, consumers will pick off loss leaders and do the rest of their shopping elsewhere. Once customer traffic has been acquired, there is a chance to sell extra items.

Manufacturing Wind Turbines in Pakistan



 

Manufacturing Wind Turbines in Pakistan

The new government in Pakistan is in place after the February 18, 2008 general elections. It is confronted with major challenges out of which power shortage is the most demanding. Due to energy shortage, the public has been warned that it should tighten its belts and get mentally prepared for massive loadshedding in the summer season. The duration of this load shedding could be as long as 9/11 hours per day!

Pakistan is at present short of 3500 Mega Watts (MW) of electricity. Though it's evident that this shortage cannot be overcome all of a sudden, still measures could be instituted that could be instrumental in meeting this shortfall. If we utilise fossil fuel for this purpose, it would be extremely costly as oil recently touched an upper limit of $112 per barrel; hence we should look for some other means which could be utilised for the production of electricity.

In this article, I would confine myself to the generation of electricity through wind. The core of my discussion would comprise manufacturing wind turbines, the machines used for the generation of electricity, in Pakistan.

Generation of electricity through wind is not something new. India, the fourth in line of countries in the world for the generation of electricity, is producing more than 8000 MW of electricity by utilising wind turbines. It's manufacturing these turbines in India and also exporting them!

One would be surprised to know that in the region of Nevarra, Spain, 70% of the region's energy needs are being fulfilled by wind and solar energy. It's a classic example of using renewable energy in any country! The logical question that automatically comes to one's mind is: "If it can be done in Spain, why can't it be done here in Pakistan?" The answer is a big Yes!

A layman would ask as to what a wind turbine is? As mentioned earlier, simply put, a wind turbine is a machine that is used for the generation of electricity from wind. It's installed on a tower at a windy location to capture wind so as to generate electricity. The faster the wind would blow; the more electricity would be produced. Once a wind turbine is installed, it would produce energy for 25-30 years free of cost as no other fuel is used except wind through this mode of production!

A typical wind turbine comprises a rotor with one, two or three blades, a gearbox, two shafts, a generator and a controller. The turbine is installed on a steel tower facing the wind. The higher the turbine is installed, the more electricity it would produce. The wind is slow and turbulent near the ground which is not suitable for energy generation.

The wind turbine operates for 363 out of 365 days a year and stopped only for two days during the year for carrying out its scheduled maintenance. If we decide to go for wind energy then the next question would be: "Should we import ready-made wind turbines from abroad or should we manufacture these turbines indigenously in our own country?

During one of my recent lectures on Wind Energy in one of the universities of the country, the same question was posed by a participant, "If we go for the wind energy option, we would be needing hundreds of wind turbines in order to make up for the shortfall of electricity. Why can't we manufacture these turbines ourselves indigenously?" I replied, "Yes, we can, if there's a will!" We can't expect the foreign manufacturers to provide these turbines to us as and when we need them due to the long lead time involved.

Moreover, we would always be dependent on the manufacturers for the supply of spares. I further told him that not only we can manufacture these turbines but also export them to other countries as it's an emerging mode of generating electricity and the wind turbines are in short supply the world over. You've to wait quite a bit for your order to materialise. So, if we have to choose the option of producing electricity from the wind, we'll have to manufacture wind turbines in our own country.

Our country is blessed with innumerable gifts from God Almighty, one of them being excellent manpower that's extremely cheap and hardworking. The skill of this manpower is just marvellous.

Here I'd like to narrate a small incident that happened during one of the country's projects of which I happened to be a member. We wanted to manufacture a certain item in one of the factories of Pakistan Aeronautical Complex, Kamra for which we had to collaborate with a French company dealing in that item. The French team visited Kamra and evaluated the expertise of our technicians.

The French team leader asked his Pakistani counterpart as to what would be the charges for the expertise of his (Pakistani) technicians if it was decided to manufacture the item in Kamra.

Our team leader just said off-the-cuff that he would charge US $10 per hour per technician. On hearing this, the French team leader jumped and declared that, leaving everything else aside, he would be saving US $35 per hour per technician straightaway as a technician of such caliber was charging $45 per hour in France!

So, this is the type of manpower we have in our country. We can employ such technicians in manufacturing the wind turbines as the day you employ them, they would be productive. By the way, Shaheen Foundation, Islamabad maintains a good record of such manpower through its excellent management system.

For generating electricity through wind, we wouldn't need a fortune. The cost of manufacture can be brought down dramatically if we follow a simple strategy. The strategy would be that we would utilise the existing manufacturing facilities of the country for the manufacture of all the parts and components of the wind turbine and assemble them at a central location, followed by rigorous testing.

During my survey of the country's existing manufacturing facilities, I got convinced that all the parts and components of the wind turbine could be easily manufactured indigenously.

The blades and the hub (the item to which the blades are firmly connected) can be produced without any hassle at Aircraft Manufacturing Factory (AMF), Kamra. If Kamra is unable to undertake this job due to its over-commitment, then there're other reputable concerns as well where this job could be undertaken.

The gearbox and the two shafts are purely mechanical items, nothing special in them. We can utilise the services and expertise of Machine Tools Factory, Landhi, Karachi. We can also utilise the expertise available at Heavy Mechanical Complex, Taxila or any other facility dealing in mechanical items. The electrical generator that's installed behind the gearbox can be produced by any of the electrical concerns at Lahore or Karachi.

The same goes for the controller that utilises electronics besides computer software. We are undertaking much more complicated projects in our electromechanical cum electronics cum computers concerns of the country. This item can be manufactured in these concerns.

As for the steel towers on which the turbines would be installed; these towers are already being manufactured in the country. WAPDA is using thousands of them on the roadside. These towers could be designed and modified as per the desired specifications for use with the wind turbines.

Regarding cables, we have numerous cable manufacturing factories in the country. If required, their existing capacity could be upgraded and augmented to produce cables of the required specs that could be used to connect wind turbines to a home, business, factory or the national grid.

In our country, we possess a lot of wind resource in the province of Sindh and coastal areas of Balochistan. We should be able to meet the major part of electricity requirement of Sindh and Balochistan through wind.

Keeping in view the urgency of the situation, the government has to move fast and solve this problem as soon as possible. It's a serious challenge for the new government. Long spells of loadshedding are becoming unbearable for the people. The situation would be going from bad to worse with every passing day.

IF WE RESORT TO MANUFACTURING WIND TURBINES IN PAKISTAN, FOLLOWING BENEFITS WOULD ACCRUE:

The locally manufactured turbines would be cost-effective due to the availability of highly skilled and extremely cheap technical manpower; The country would not be dependent on foreign manufacturers for spares. Non-availability of spares could be a major impediment towards the successful completion of any wind turbine project. The country would save precious foreign exchange.

Rather, it would earn foreign exchange by exporting the indigenously manufactured turbines to other countries.. The country would also save a huge amount of foreign exchange by curtailing the import of fossil fuel as each turbine would be utilising wind for 20-30 years which's free.

It may be mentioned that all the leading manufacturers of the world have started the same way ie by having a modest start in the beginning and then growing into big manufacturing giants.

Lastly, I must say it with conviction, based on my more than thirty years' experience in the technical field that, instead of setting up manufacturing facilities for each and every part of the wind turbine, we should utilise the existing facilities of the country to their optimum level for manufacturing these parts. Wherever required, these facilities could be augmented and upgraded.

It only requires excellent management and sincerity of purpose and nothing else! By following this strategy, the cost of manufacturing would come down drastically! If we plan carefully and apply all tools of modern management, there's no reason why we shouldn't make this experience a thundering success. We have all the facilities and expertise at our disposal.

Our manpower is second to none. The only requirement is that we should harness our manpower and facilities to get the maximum out of them. Iqbal, the poet of the East has said: Zara num ho to yeh mittee bari zarkhez hai saqi, meaning the earth of this country is highly fertile if we provide some water to it!

Force Field Analysis



Force Field Analysis

Force Field Analysis is a simple but powerful technique for building an understanding of the forces that will drive and resist a proposed change. It consists of a two column form, with driving forces listed in the first column, and restraining forces in the second.
The force field diagram is derived from the work of social psychologist Kurt Lewin. According to Lewin's theories, human behavior is caused by forces – beliefs, expectations, cultural norms, and the like – within the "life space" of an individual or society. These forces can be positive, urging us toward a behavior, or negative, propelling us away from a behavior. A force field diagram portrays these driving forces and restraining forces that affect a central question or problem. A force field diagram can be used to compare any kind of opposites, actions and consequences, different points of view, and so on.
In the context of process improvement, driving forces could be seen as pushing for change while restraining forces stand in the way of change. A force field diagram is used to analyze these opposing forces and set the stage for making change possible. Change will not occur when either the driving forces and restraining forces are equal, or the restraining forces are stronger than the driving forces. For change to be possible, the driving forces must overcome the restraining forces. Usually, the most effective way to do this it to diminish or remove restraining forces. It can be tempting to try strengthening the driving forces instead, but this tends to intensify the opposition at the same time..
The balance sheet structure of the force field diagram makes it applicable to situations other than comparing driving and restraining forces as well. For example, you could use it to list possible actions and reactions, compare ideal situations and reality, or in negotiation, weigh what you want from someone with what they would have to face if they agreed.

Setting Up Your Force Field Diagram

The force field diagram pictured here shows how teams can list driving and restraining forces, and estimate their strengths.
  1. Draw two columns, with one header running across both.
  2. Write the planned change in the header area.
  3. Label the left column "driving forces", and the right one "restraining forces".
  4. List the forces in the two columns.
  5. Encourage creative but realistic thinking.
  6. Forces seek equilibrium. To encourage change, create asymmetry between forces.
  7. Which of the restraining forces can be removed or weakened?

Force Field: Other Uses

You can also use a force field diagram to:
  1. List pro's and con's.
  2. List actions and reactions.
  3. List strengths and weaknesses.
  4. Compare ideal situations and reality.
  5. In negotiation, compare the perceptions of opposing parties.
  6. List "what we know" in the left column, and "what we don't know" in the right.

Safety Stock



Safety Stock

First of all, here's the formula so you don't have to dig through my well-written article for it.

Safety Stock:  {Z*SQRT(Avg. Lead Time*Standard Deviation of Demand^2 + Avg. Demand^2*Standard Deviation of Lead Time^2}
If that wasn't clear to you, I suggest reading on..  This article will explain in detail what safety is used for, and how to use it.
Inventory management is about two things: not running out, and not having too much. Our desire to not run out, along with uncertainties in demand and supplier lead times are why we have inventory in the first place. Essentially, inventory is a reserve system to prevent a stock out. However, as important as it is to prevent such a stock out, we also don't want to hold onto too much inventory because of holding costs. So how do you balance the two and what is the right amount? More importantly, when should you re-order in order to prevent a stock out? The answer to this can be determined by obtaining and applying the following information about the inventory you wish to manage.
Re-order Point (ROP)

1. What is the average lead time for the part/finished good that you need?
2. What is the standard deviation of that lead time? I
 
t is very important to track how long shipments take from you suppliers. If you are not doing this, start. It should be your top priority. Assuming you have tracked the data, excel can very easily help you determine your standard deviation. In excel, go to the toolbar and click on Insert, then click on Function, and choose STDEV and click ok. Then, enter in as much lead time data you have and presto, you have your standard deviation.
3. What is the expected demand you are working with?
4. What is the standard deviation on this demand? 
 
Perhaps this is something you will be familiar with from experience, however, if not, this is something you should be able to squeeze out of Ted from the marketing department.  One way to find it is to look at historical demand and use the STDEV function in excel to determine it.
5. How sure do you want to be that you aren't going to run out?
 
 90%, 95%, 98%, 99%? Whatever you decide, this will become your service level. Using this percentage, a statistical z-table should be used to get the corresponding "z-value." A good z-value webpage can be found at http://www.inventor yops.com/ safety_stock. htm. So, for example, if you want a 98% service level, you would use 2.05 as your z-value.
Ok, so you've gathered this data, now here's what you do with it.
(Underlined section is safety stock)
 
Re-order point=Average Lead Time*Average Demand + Z*SQRT(Avg. Lead Time*Standard Deviation of Demand^2 + Avg. Demand^2*Standard Deviation of Lead Time^2)
In this formula, the first term (Average Lead Time*Average Demand) is the average demand.
The second term {Z*SQRT(Avg. Lead Time*Standard Deviation of Demand^2 + Avg. Demand^2*Standard Deviation of Lead Time^2} is the term that allows for the safety stock. In other words, the second term is the optimal safety stock level.
It is not simple to gather all the data that is needed for the calculations. For a product with multiple parts, each part needs to have its own re-order point calculations and its own safety stock calculation. This can all become very confusing if proper computer modeling is not employed.
Although I mentioned excel earlier, excel is probably not sufficient for your company's software needs. If you have not already done so, it is very important to look into an integrated software package for these calculations and many others.
