Let’s try to guess that how many presidents, vice presidents, deputies are existed in the world, more than 1 million or maybe more than 10 million; however, how many of them are effective leaders? Probably less than 10.000 people out of 7 billion people! How many of them are good leader? Probably less than 1000 people
Today, I want to talk about the difference between effective leadership and good leadership. Although both of them seem similar to each other, the difference is morality. The effective leadership may not care about morality. Have you watched the Wolf of Wall Street? (If you haven’t watched it yet, do it as soon as possible) The movie is about the life of Jordan Belfort who is an impressible effective leader; however, he was convicted of fraud crimes related to stock manipulation and penny stock boiler room. So basically every effective leader is not a good leader. In the movie he seems as a very influential leader, reinvented the business culture.
The effective leadership is more about how effective the leader when influencing his/her followers and motivating them. According to me, it is not so easy to run into with either a good or an effective leader in the meantime, because there are not plenty of them. Good leadership is something slightly different than effective leadership in terms of morality issues as I mentioned. Good leaders are generally well-known by almost everybody, such as Gandhi, or Martin Luther King. In this module we aim to be good business leaders that have respect to business ethics, pay attention to morality.
Up to today, I haven’t had a chance to work with or study with a great leader, but I believe that one of the most effective leaders in the world is my homeland’s prime minister who is Recep Tayyip Erdogan.

Most of the WMG student wants to get good coffee from vending machines in common room. However, even coffee machine works properly, it doesn’t provide good coffee. The coffee is all watery and does not have good taste and proper coffee feel to it. This issue was raised in SSLC meeting, but wasn’t solved. Actually we could get good coffee from Digital Lab Building; however, this week it is prohibited by unknown people. All in all we request WMG to provide us good coffee in common room, at least provide the same coffee machine as the one in IDL. Support us and intensify our voice!
Here is the link to support:

After one week break, it was a good beginning with Design for X. Design for X can be seen as a design for everything such as design for manufacturability or design for environment. For instance, if we assume that we are dealing with a project which is about manufacturing a water pump. We can categorize our design aims into different categories just I did as above. Actually this module provides us how much design has a role or impact on innovation. Yes, I will call it innovation! DesignX looks the project from different perspectives of views. For instance, not only covering the issues about serviceability or reliability of product in future, but also may include design for environment. Actually, DesignX wants to show that designing a product is not just manufacturing the product, but also being ready to following issues.
In today’s case study was about an aircraft crash in 1989. As a mechanical engineer, I exited about both today’s topic and case study, because I am very familiar with this topic and I have been doing this kind of analysis more than 5 years. The video showed us that due to explosion at the tail engine, hydraulic system was lost. With pilot’s outstanding exertion, 185 people were survived surprisingly, even 111 people died.
According to our team’s great investigation and my interpretation, due to lack of know-how of one more vacuuming process which is called triple-vacuum process in the beg-70s, the melted titanium reacted with air and had impurities in its micro-structure. These impurities caused cracks on the edge of fan disk which could be seen minor issues on those days, when the engine was freshly manufactured by GE. However, cracks can propagate over time due to fluctuating pressure levels and then reduced the strength of parts furtively. Even though engineers estimated fatigue life (useful life) of engine 25, it suddenly exploded in 17th year and gave damage to hydraulic system. Second major design failure was that there was no back-up hydraulic system that can be operated in case of emergency. Actually, nowadays aircraft are supposed to be checked by ultrasonic devices in order to prevent any fatigue problems and the aircrafts have 3 have hydraulic systems.

Even though the DFSS and original Six Sigma sound like similar terms, there are several differences between them. The Design for Six Sigma (DFSS) module is more end user based than Six Sigma, because Six Sigma aims to get rid of variability and incapability in the system and cares more about internal issues in the business. However, DFSS captures the wide perspective of market. Although it is stated in many sources that DFSS is product based, I don’t agree that it is simply product based because products are purchased by customers and they should be designed with respect to customers’ desires and beliefs, just as how we were taught in our Creating Busıness Excellence course. Paul Roberts wrote in class: “product and customer” on the board, and asked which one king is. Then he said that CUSTOMER is the KING! Customers have a free will and they can buy whatever they want, though the product is foolish! Even your product may be the most qualified product ever on the market or the most innovated, in some cases it doesn’t work!
However, DFSS catches and interprets customer feedbacks or thoughts, and then produces a new product according to the design X approach. Design for reliability, and maintainability are the subgroups of designX.
Lastly, I am enthusiastic about PEUSS and glad to have 1 week break :) Now we should read and prepare for the lecture week!

Honestly, I haven’t realized how much the PIUSS module improves my knowledge about applied statistics in industry. Although I have taken statistics class during my undergraduate, I haven’t been curious about how to use them in business life. However, after the PIUSS module, I learned not only the most common statistics tool, such as SPC and Taguchi Method, but also the importance of Six Sigma. It is really interesting to me because now I am applying statistical principles to practical uses.
I have been reading lots of sources about the Six Sigma since the beginning of the study week and I realized that during just one week of the module week I understand almost the whole context perfectly. Of course this is not true but that is how I felt at that time. Also I am going to select Lean Six Sigma as my project topic as well because of this interest.

As I mentioned on my previous post, SPC is the one of the important tools for monitoring the system behaviour. SPC can be seen as a six sigma tool; however, the people can use it without any 6 sigma knowledge as well.
Okay , let’s come to draw a SPC chart.
Assume that we work on the quality department and we take regularly 2 samples for checking the dimensions of the products. And we do this observation 3 times: at 11am, 3pm, and 6.30pm in a typical working day (Totally we can say that we measure 6 products a day). Moreover, customer told us that the parts suppose to be (150,00mm- 151,00mm) in those dimensions. Okay I am going to create my own measurement chart step by step.
I wrote the every sample which is collected from production. Firstly I wrote down the difference between highest number and the lowest in the same day. And then I calculated the average of difference by adding whole ranges of days and then dividing to 6. And it is 1,035(Range_bar). X_bar means that average of samples which are collected in same day. After I calculated X_bar, I can reach X_bar_bar easily which is average of average of samples.
Finally, the Upper Control Limit equals to X_bar_bar+ (0,483*Range_bar). And Lower control limit equals to X_bar_bar – (0,483*Range_bar).
[0,483 is a constant and can be founded on almost every tables.] My n is 6, so it is 0,483
I drew my own SPC chart according to assumed values. Actually we can use this tool for almost every application on the industry. As you can see Brown line was our “upper control limit” and green one is “lower control limit”. And Blue demonstrates the system behaviour.
As you can see from the graph the system behaviour stays in the limit; however, the limits are not capable of customer tolerances which is 150,00-151,00, even though the flow is stable.
On the next post, I am going to calculate capabilities!
Important Note: Before reduce the common variations in the system, system or application should be removed from any special causes.

Six sigma was developed by Motorola engineers in 1980s. Motorola saved more than $ 16 billion as a result of six sigma effort. So how did Motorola save that much money? And what is the aim of the six sigma? Before Process Improvement using 6 sigma (PIUSS) lectures started completely, I always thought like that this 6 sigma methodology must be a miracle. The exact aim of the six sigma is reducing the defect levels by eliminating the variances in the system. By reducing the defects level on the production, we use Statistical Process Chart (SPC) in order to monitor the volume of production. Before we start to reduce common variances in the production, the system must be stable which means that there has to be no special cause. Special causes can be emerged by either passing the upper /lower control limits or stays on the almost same level for 8 measurements. After we understand special causes on the system and solve them by using cause and effect diagram (fish bone method), we are ready to investigate the common variances that affect system behaviour. We need at least 20 points for drawing a real SPC. I will talk about SPC more on the next post!
Industry needs 6 sigma, because it reduces defects by decreasing the variances. Moreover, the most important point on the six sigma ideology is that industry does not reduce its number of defected parts by producing more products (they do not affect to overproduction) and spending more money. On the contrary, 6 sigma helps company saves money by reducing the some types of wastes (defect, inventory, motion, etc). Actually six sigma creates by According to six sigma levels, if a typical industry reaches 6 sigma levels; it means that they can run maximum 3.4 defected parts into in a million! It sounds like a dream! For instance, one of the significant users of 6 sigma methodology in industry is General Electric. GE announced that they saved around $ 350 million in 1998. A Fortunearticle stated that “of 58 large companies that have announced Six Sigma programs, 91 percent have trailed the S&P 500since”.
By the way, I am really interested in 6 sigma methodology and I think that I will apply green belt to PMI in order to gain more knowledge about it.

Although I have some brief knowledge about excellence pathway for industry implications, it was an interesting and informative module. After Paul and Chris Hakes explained how organisations should achieve excellence rank, it attracted my attention more and the class presentations and games foster me to learn more. And I finally focus more on continuous improvements which seem like difficult but are very essential for being sustainable and having quality management. Also I agree with Paul’s idea that hierarchy in the organisation from the lowest rank worker to executives should be changed!! But how? And then we decide to implement it reversely in order to create collaboration environment in business instead of competition; therefore, each rank must be ask and help its one lower rank in terms of knowledge and experience sharing. On the other hand, one of other significant points is building learning organisations which are open-minded to learn more and more and keep its mistakes in mind. All in all, CBE is going to form the foundation of this master degree and other modules are going to be give richness.

I have read an article on HBR (Harvard Business Review) which explains how Walmart (world’s second large public corporation according to Fortune 500) has an achievement on society results.
With respect to EFQM, excellent organisations achieve and sustain outstanding results that meet or exceed the needs and expectations of relevant stakeholders within society. Generally companies hire PR people in order to prevent awful headlines. Then, CEO shows up and tells “We are misunderstood and we should need to tell a good story”. Do not tell a good story! The public can embrace company if CEO shows up and makes pretended press-conference instead of criticizing company according to mistakes.
After the deadliest and destructive hurricane Katrina hit many houses and killed 1883 people, Walmart provided meals, cash, emergency supplies by trucks. Those were the right things to do.
And Walmart set big goals in areas such as sustainability, women’s economic empowerment, and more-healthful food. So giant companies don’t achieve enormous revenues or market-share incidentally, they take 360-degree approach to the work, engaging entire supply chain, customers and communities. The multinational big companies take on high risks, because their sales. It means that negligible failures can create terrifying outcomes from the society’s perspective; they can lose great revenues suddenly. According to article, taking on large social issues can be compatible with building a stronger business, and I agree with. Instead of telling a better story to public, be a better company in terms of society like Wal-Mart.
EFQM has 4 results which are customer, people, society, and business results. Especially in the retail stores like Walmart or Home Depot, society results have a high impact on customer’s choices, because they address with end-users who care about environment and humanity. EFQM measures could include perception of environmental impact, image and reputation, societal impact, workplace impact, and awards and media coverage. Those measures give trust company to reach more people and sell more products.

This cycle is known as Deming Cycle. Although it was created for the improvements in business environment, actually this loop is used in many cases by us. I believe that this cycle forms also the structure of learning process. Let’s investigate all of the steps and give examples:
What a boring word, isn’t it? Everybody has been talking about how preparing plan is important. However this is the fact that “plan making saves time and money in every ambient”. For instance, housewives prepare the shopping list in order to categorise the needs and places according to discount booklets of supermarket which are distributed by mail or experiences which they have. Actually, we are planning everything in our lives unconsciously, because due to requirement of surviving we should use our resources and capabilities orderly and efficiently. Our resources may be time and money and capabilities may be physical or logical behaviours that we can execute in “Do” step!
Also plan making not only reduces the uncertainties in our life, but also minimize the impulsive and arbitrary decisions. Preparing plan reduces the probability of catastrophic failures in every platform.
No one can have an experience or feedback, before experiencing it. After we made plan or agenda, trial is necessary for collecting data from system. With this act we compare the real results with expectations. For instance, there is middle-size factory which produces electronic equipments for notebooks and we work as a management team. After we prepared our new production line-up for a recently innovated product, we should try to produce it and instead of discussing the expected results in meeting, we need real outcomes. The real result of test is really important in order to check them with anticipated ones. These tests take sometimes much time in some sectors, especially manufacturing sector. For instance, BMW, well-known German automobile manufacturer, put new cars on the market in every 7 years. During 7 years, the department of research and development tries it in every condition which car may be deal with. However, some firms do not have a capability taking a risk and want to observe the outcomes in small perspective. (**)
**Sometimes this step called as “pilot practice”, because most companies do not want to take serious decisions. Pilot practice means that try out the application in a small dimension instead of apply it completely. **
How can we correct our mistakes or wrong decisions? In this step of PDCA loop, we are going to compare the results which have taken from Do-part with the expectations on Plan-part. Sometimes the decisions taken in Plan part may be misleading and we are sure to be on right way. According to me, checking means that “deriving lessons from mistakes”. After we learned from mistakes, new improvements are unavoidable.
We have already planned, tried, and checked! We should finalise and keep it sustain our attempt. Act step shows us how people work well. It is time to show and prove people our knowledge and work in this step. Reaching excellence level in production is not a dream, but it requires much willingness an adaptation to excellence ideology and patience.
Even we have finished the cycle; the most important principal about PDCA-cycle is keeping it sustain. It means that we should follow this path for all new improvements or innovations. And this will give us continuous improvement in long-term. After this cycle rotates in a time, the quality of product will improve and company can achieve excellence.
