Success of Improvement Initiative Depends on People

By Anthony DiBona Jr.
Whether it is Lean, DMAIC or DFSS, Six Sigma boils down to improving business processes. And irrespective of the methodology employed or the scientific rigor behind it, every process improvement initiative – if it is to be successful – has to be approved, understood and implemented by people. Given the body of work published about human inertia and change management, it should come as no epiphany to the quality professional that people are notoriously resistant to change, or may embrace change for the wrong reasons. Successful Six Sigma practitioners have a variety of methods for diagnosing and overcoming this inherent resistance – this is one.

A key component of process analysis is the notion that one should maximize those steps that add value and minimize or eliminate those steps that do not add value. In its simplest form, the idea of value-added is to do only those tasks that a customer recognizes or expects as being essential and is willing to pay for. Anyone who has been active in process improvement knows that most business processes are chock-full of non-value-added steps, possibly as high as 70 percent.

Imagine how a person working in a department, doing their level best every day, would feel if they found out that much of what they do is without value? Their level of job satisfaction would plummet and they would be disenchanted in leaders who had them completing tasks that no customer needs or wants. Such pockets of inefficiency are not the mark of a company dedicated to quality. Yet people are only human; nobody wants to lose their job. Thus, companies that foist quality initiatives on workers who live in fear of their livelihood are implementing a self-defeating program.

Conversely, if workers are motivated to look at what they do from an overall customer service perspective, they are more likely to be satisfied in their jobs. And they will be more confident that any effort to refocus their labor to give more value to the customer will in turn be valued by their employer. Thus, they are far more receptive to embracing constructive and innovative changes that a quality program may advocate. Such an employee perspective is essential for an organization's overall success.

Here are two example of how to get on top of this problem:

An Example on a Navy Ship
While on active duty in the U.S. Navy, an officer stood duty as officer of the deck (OOD). The officer of the desk is an important position because he or she is running the ship based on the captain's authority. During flight operations with an aircraft carrier or maneuvering in close quarters with other ships, an OOD can get pretty busy and mistakes can be devastating. It was not unusual to simultaneously have several radio speakers blaring with all manner of information – a lookout reporting a ship on the horizon, engineering reporting a minor malfunction, navigation reporting a time to make a course adjustment, along with a new combat exercise about to commence.

In the middle of all this a young sailor, fresh from boot-camp would report in his loudest, post-adolescent voice, "Sir, lunch is now being served on the mess-decks!" The Navy calls this lad a "phone-talker" and his expected response from the OOD is, "Very well." The "very well" signifies to the sailor that the OOD had heard and understood his message. A terse "very well" is fine when the message involves lunch for the crew, but is insufficient when the information involves the ship on a collision course with a carrier. Moreover, this young sailor is duty bound to repeat his message until he receives a "very well" from the OOD. (Note, it matters not to the phone-talker that the OOD is busy answering a radio signal, responding to a lookout, contacting engineering, and giving orders to the helm. If a "very well" is received, then the mission is complete. In short, these sailors know what to do, but they do not know what they are doing.

Was it unusual for an OOD to utter a "very well" without understanding the message, just to stop the hollering? Yes. Was that a risky move considering what might be being missed? Another, yes.

After several months of this nonsense, the officer tried a new approach. During a quiet period, he spoke with some of the phone-talkers and asked them if they realized what they were reporting. Each admitted that, other than lunch or some other administrative matter, few had any idea what they were reporting and what it meant to the ship. However, all seemed anxious to learn and were immediately receptive to the attention the officer was giving them. The Navy is full of jargon and codes so it is not unusual that these young men and women would not comprehend what they were conveying. In fact, they were trained not to think or to summarize, but to repeat word-for-word what they were told over the phone. Mind-numbing? Absolutely. Necessary? Well, maybe during the War of 1812, but not in today's modern Navy with well-educated enlisted people.

What the officer did then was to begin to move around the training these sailors had received and to begin educating them about what their messages meant. Clearly it did not take a genius to grasp that an announcement about lunch or mail-call could wait until the OOD responded to the radio message from the admiral. More importantly, it was just as easy for them to appreciate the how critical it was that they ensure the OOD fully understood that there was a submarine about to surface 1,000 yards ahead of us. A simple "very well" would not be good enough. In illustrating the point, once they understood what the messages meant, the officer asked them to consider his position as OOD. What if they were doing that job, how would they want the information passed on to them so they could always make the best decision. None of them ever failed to see the point when viewed from that perspective.
As one might suspect, it did not take long for the intensity level to ratchet down somewhat. There were still radios blaring, lookouts and engineering reporting, course adjustments and combat exercises, but there also was a newfound cooperation between the OODs and phone-talkers. Now, instead of a constant drumbeat of inane information that clearly could wait, mixed in with a crucial element that could not, real communication between sender and receiver had been achieved. Communication that included true understanding and comprehension for all parties involved.

However, there was another unintended consequence of the officer's behavioral experiment – the phone-talkers felt better about themselves. Their pride increased. They now grasped how important their role was to the ship, its operation, the crew's safety and to the OOD. As their knowledge about the messages and reports increased, their pride increased. As their pride increased, their ability to perform their job improved. In short, it was a win-win situation. The OOD had better control of the situation and the phone-talkers had a real mission. These sailors now knew not only what to do, but also knew what they were doing.

An Example in the Business World
Fast forward to the ex-Naval officer's life as a management consultant. He now is the guy leaning out business processes and having to tell people that much of what they have been doing has little value and must be eliminated. Many workers immediately jump to the conclusion that if what they do has no value, then he was saying they have no value. There starts the resistance. He had to find ways to overcome people's natural resistance to change in order to see his recommendations as a consultant be implemented and the savings realized. The same approach he discovered while in the Navy became his go-to method for managing change.

Several years ago a regional bank's operation site needed help. In simple terms, the site's staff was opening envelopes containing checks as invoice payments and depositing the checks into accounts for various small, medium and large businesses. Additionally, the site also processed payments for a variety of government agencies. The operation suffered from error rates that were off the chart, unusually high turnover and extremely low morale among the work force. It was clear that no manner of process improvement would stick if it was not possible to somehow turn-around the employees' attitudes and make them proud to come to work each day.

Using his Navy approach as a guide, the consultant and his team designed and implemented separate processing teams. These teams were tied to the industry they supported. For example, one team was dedicated to healthcare insurance providers; another to real estate businesses and a third handled child-support payments. Then by way of a series of training, or rather education classes, it was explained to each person how their role fit into the big picture.

For example, for the real estate team, the consultants explained that the checks they were processing were in fact rent payments from people just like them. Real-life examples were used to illustrate what might occur if they did not do a quality job: "Imagine what might happen if you fail to deposit that check in the right account? A person could come home and find all their belongings on the street and their apartment rented to a new tenant – all because you didn't pay attention to your work." Consultants explained to those handling child support payments that if they failed to process a father's check properly, he could be accused of being a "deadbeat dad" and face arrest, when in fact he had mailed in his payment. This approach with these examples hit home. Employees started to pay closer attention to their work because they now knew not only what to do, but they also knew what they were doing. They understood the value of their work.

More importantly, just like at sea an unintended consequence occurred. Because the consultants had designed and implemented teams that handled only certain industries, employees were now responsible for specific accounts that they processed every day. Previously, any employee could be told to process any account at any given time. As a result there was no ownership. Since assignments were given out at random, when a business customer called with an issue no one in management knew who processed that account on the day in question. Under the new system, employees were held responsible for their work. With responsibility came accountability. And just like in the Navy, this accountability led to pride. Each team began to track errors and productivity; not because management insisted, but because they wanted to demonstrate to each other which team was best. Additionally, instead of business customers wanting to talk to a supervisor or a manager, those same customers now wanted to talk to their processing clerk. Open customer was overheard saying to a supervisor, "I don't want to talk to you, I want to talk to Marcia; she's the one who handles my account." It is easy to understand the increase in self-esteem felt by members of the staff. Their work was valuable to a customer. They were valuable to a customer.

When the bank project was completed, customer-reported errors had declined by 63 percent and were continuing to fall. Productivity had increased by 20 percent and was on the rise. Turnover was declining and morale was high. In short, the company, its customers and the employees were all better off.

Lessons Learned from the Two Examples
Recommendations to improve business processes must be approved, understood and implemented by people. People are naturally resistant to change, but become particularly so when they believe a change initiative is attacking them as workers. In order to be successful, a change initiative must not only advocate value-added processes, but also value workers for their ability to carry though these processes. So, what are the universal features of the two examples that a Six Sigma professional can use? Consider these points:

People are the key to successful projects. Overlook the people, and their likely resistance, and a project is doomed. Management and team leaders must value the work of everyone. That does not mean all tasks are value-added; they are not. Obviously that is the reason for an improvement project. Leaders on all levels must develop and maintain an attitude that the work someone does is worth both the leader's time and the workers' time. If workers sense that a leader looks down upon what they do, they will resist recommendations and perhaps sabotage the project. By the way, this attitude must be genuine. People will see through a charade and can detect a phony.

Employees should be accountable. That does not mean dishing out sanctions for not following disconnected and meaningless procedures. If someone cannot see the result of their labor they will begin not to care about what they do. When a business leader asks someone why they do a particular task and they get a shrug and the answer, "I don't know," is there any wonder about poor attitudes and poor quality? People want to do good work. Good leaders show them how and hold them accountable to a standard. They will reward the business with positive results. However, with this approach comes increased management responsibility as well. Training, metrics and pay-for-performance all become more important.

Everyone needs to know how what they do contributes to the company and its customers. Nothing is more frustrating than to think what one does for a living has no value. Many employees do not know how their jobs – the tasks they perform everyday – contribute to the success or failure of a company or its customers. Management needs to teach them. The opportunity in this regard is incredible. When workers know that their job is important they will approach it with a new found vigor and pride that can only lead to higher quality, productivity and morale.

Six Sigma quality and productivity cannot be achieved by workers who simply punch a clock. Quality and productivity come from workers who care. Management must not stop training at the task. Good people should not merely know what to do; they must know what they are doing.

How to Explain Six Sigma by Using the Profit Triangle

By Bas Franken
Once a person becomes a Master Black Belt or deployment leader within an organization, they may spend a lot of time explaining to other people what Six Sigma is and how it can help the company. They may have to convince many skeptical people, who always see the deployment costs but not the benefits.

Two things must be clearly understood before trying to explain Six Sigma to anyone.
Focus on Financial Savings


Financial savings is a key objective of Six Sigma. While this should be fairly straightforward, it is not always clear up front what the (hard) savings will be. Finding the true costs of poor quality can be a difficult job. For example, if a project is aimed at improving the throughput of a certain machine or process, but the current demand is lacking, then there will be no hard savings. However, if the demand is 20 percent above budget and the project team can improve the throughput, this could mean a significant profit increase.

Another difficulty in finding the true costs of poor quality is that when working on the main problem, sometimes a variety of smaller costs and issues are resolved as well. Usually those issues are not listed when the financial analysis is being made. In most successful projects, one improvement affects another. For instance, improving productivity may boost morale and decrease material costs.

The focus on savings can be made even more difficult when company controllers are afraid to be held accountable for the savings and lack the operational skills to see the benefits.


Improving the Total Business Process
In addition to achieiving financial savings, Six Sigma is a program that helps improve the total business process. Six Sigma is not a group of internal consultants (Black Belts) available to fix processes when they are broken. Six Sigma should evolve in a structured continuous improvement program in which everybody has a place and a clear goal.

With this background, the question remains: "How do you explain Six Sigma to colleagues?"


A tool called the profit triangle can help clearly describe Six Sigma's role in the organization. It focuses on both continuous business improvement and financial savings. Often used in marketing theory, the profit triangle simply shows what a company needs to deliver to its customers to make a profit.


All Sides of the Profit Triangle
The three sides of the profit triangle are value creation, internal operations and competitive advantage. All are important for a company to be profitable. An organization must excel in all three areas if it wants to be among the best in class. Like a triangle, all three aspects are linked – a company's performance on one side will have an impact on the other sides.


If its internal operations are not well structured, a company will find it difficult to create value and be highly competitive. Six Sigma began as a focus on improving internal operations. The methodology is targeted on the processes within an organization. Of course, it is better to build in excellence when business processes are first being developed and designed, but often operational processes have to be improved to be made excellent afterward.



Six Sigma and its tools are not limited to production processes. Sales, marketing, and research and development departments also are filled with processes that can be improved. While a company might have a natural competitive advantage because its competitors have such poor products or sales efforts, in today's marketplace this is unlikely. Therefore, organizations need to excel in all areas.


Companies that use Six Sigma are striving for operational excellence. Six Sigma is a data-driven, structured, continuous improvement program that works at a company's foundation to help it reach operational excellence. Six Sigma can support all three sides of the profit triangle.

Operational excellence is the goal – Six Sigma is a means to that goal. And the profit triangle can help explain Six Sigma's role.

How To Select A Six Sigma Quality Improvement Project

You've identified a process improvement area within your business or department. It's easy to figure out what comes next -- just fill out a team charter, select the team and team leader, form the team and get out of the way, right? Well, sort of...

Why Select Projects?
Selecting the right project can have a tremendous effect on your business. If done properly, processes will function more efficiently in 3 to 6 months, employees will feel satisfied and appreciated for making business improvements and ultimately shareholders will see the benefit. If project selection is done improperly, a project may be selected that doesn't have the full business buy-in, project roadblocks may not be removed due to other business priorities, the team may feel ineffective and the end result may be less than ideal. No one wins in this situation, especially the quality manager who may look to these same people the next time a need arises. So how do you make sure you select projects in-line with business priorities?

Select Projects In-Line With Your Business Priorities
Here are five guidelines to keep handy the next time you are evaluating potential quality improvement projects:

  • Ask your business leader for the three greatest issues facing the business. Make sure your project is one of the issues or is directly related. This will ensure that your management team is giving the project the proper attention and quickly removing roadblocks.

  • What are the three greatest issues as seen from the eyes of your customers? Look through customer complaint logs, listen to call center telephone conversations and call customers that have stopped your company service. Create a pareto chart to prioritize issues. This will help with project prioritization and project selection.

  • Is the project manageable? Can the project realistically be completed by a team within six months? If longer, you may lose members as they move to other jobs or the team may feel frustrated that they're not making a difference.

  • Will the team have a measurable impact on the business processes or financial bottom line? Don't embark on a project without knowing what the benefits are to the business. This will keep your team motivated along the way.

  • What is your process capability? If you haven't been measuring your process, how do you know it needs improvement? Make sure you know what amount of defects the process is currently producing and define your project desired outcome.

Every business is different and you should ensure that your specific priorities are taken into account when evaluating and prioritizing potential projects. Spreadsheets or databases can help you organize potential projects by assigning evaluation categories, values and weightings to create a consistent selection process.

六西格瑪/六標準差(Six Sigma)解決問題的步驟

通過五個步驟 Define(界定機會), Measure(量度績效), Analyze(分析機會), Improvement (改善績效), Control(控制績效) 即廣泛傳誦的 DMAIC 以此為核心模式來突破現況。

六西格瑪(中國大陸及香港用語)/六標準差(台灣用語), 是一套有系統及以數據為本的方法, 集所有先進 質量管理手段於一身, 用作盡量減少流程中的缺陷, 包括由""製造流程" 至 "交易流程", 並且適用於產品及服務。以接近其品質目標標準之品質頂尖水準程度, 並減少 "不良品質成本" (Cost of Poor Quality)、"縮短交期" (Cycle Time Reduction)、增進顧客滿意度的管理過程和企業衡量。

美國摩托羅拉公司 (Motorola) 在 80 年代後期至 90 年代中期, 由公司總裁 Jack Welch 大力提倡首先推動 Six Sigma 行動推廣。自 1995 年通用電氣公司 (GE) 引入以來, 每年為 GE 帶來數 以億計的收益, 現己成為 GE 三大核心價值之一 (Six Sigma、產品服務、全球化) , 且揚名企業界。Six Sigma Management / Methodology 強調一切以客戶為中心, 加強流程控制, 改善品質, 最大程度地滿足客戶的要求。現時除了通用電氣及摩托羅拉外, 很多位列於財富 500強的製造型企業包括三星、東芝、柯達、杜邦 、IBM等都在使用 Six Sigma 系統。

基本上, "Six Sigma" 採取預防導向的問題解決法、強調主動性的行為、基於資料而做決定、採取長程的規劃、將人力視為資產而非成本, 並且強調團隊的授權與標竿學習。實施 "Six Sigma" 的公司, 以此達致全公司上下目標及定位一致,故此工作間能夠一致地將產程的誤差率控制在百萬分之三點四以下, 成為接近完美品質的標準。

為了推動 "Six Sigma", 需要設計 “戰士層級” (Warrior Class), 使員工接受 "Six Sigma" 所要求的統計訓練, 通常這些層級以空手道的技能高低來命名, 包括:黑帶大師/專家(Master Black Belts)、黑帶(Black Belts)、綠帶(Green Belts)、黃帶(Yellow Belts)等。

二十一世紀是一個講求變革的世紀, 任何企業經營者想要立足於這個全球化的市場, 必須不斷的消除公司內部各種作業流程的變異到幾乎近於『零缺點』的完美境界。Six Sigma正是一種追求「最小變異」幾乎近於『零缺點』的經營管理思維模式, 它是借用統計學上的常態分配與機率模式, 來主導企業經營的戰略與戰術, 此一經營理念在強而有效的管理工具配合之下, 可以依循公司的經營策略、營運目標, 從產品研發、作業流程改善、品質提升、一直做到售後服務顧客滿意度的提升。

究竟, 什麼是 "Six Sigma"?來源的由來又是甚麼呢? Sigma = σ, “σ" 是一個統計學術語, 為每單一的平均偏離值, 用來衡量一個過程的質量。 σ的量級為2至6, 代表百萬個產品之中可能有多少個缺陷。Six Sigma 就統計學而言是指流程平均偏離1.5 Sigma情況下, 在1百萬個元件(機會)中, 只產生3.4個不良或是錯誤的品質水準。單從3.4ppm, 就不難看出Six Sigma帶給企業有何突破性的效益。對於一般公司來說, 就是能夠達到4σ就是一個不錯的成績了, 這相當於每百萬個產品中有6000個缺陷(合格率為99.4%)。因此, 企業要想在知識經濟時代裡脫穎而出, 就非得重視Six Sigma專案的接受與應用。

Six Sigma 現已廣泛地被製造業內的部門如採購部、客戶服務部、產品設計部、財務部等所採用。近年在銀行界、旅遊界、醫療美容界、物流服務界等的客戶服務流程設計及針對個人需要而發展的產品及服務, 亦廣泛採用六西格瑪系統去確保客戶能享受到由公司所提供的最高質量服務, 從而令客戶稱心滿意。

Six Sigma Methodology 為企業實施高質量經營的管理理念, 使這些企業不但節省數以億元的開銷, 而且還大大提高公司對市場的反應速度, 鞏固日益變化的客戶關係, 從而為獲得並保持在國際市場上的競爭優勢提供了一個非常有效的管理戰略。
