Within these two weeks on Process Improvement using Six Sigma module, I gained a lot of knowledge and benefits such as listed below:
1. The theory, concept, and function of Six Sigma, the relationship between Deming’s theory (SoPK) and Six Sigma (DMAIC), the benefit of implement six sigma in daily work, the combination between six sigma and lean (8 waste), the importance of six sigma in organizational learning. Noticed that the teaching and learning methods are variations, i.e the combination of classroom lecturing, workgroup presentation, invited the guest speaker from the consultant (PMI) and practitioner (GE), and online learning. From a few simulation done in class, such as :
a. Red and white bead experiment : I learned about the management role in managing the balance between system and people so they are able to work together effectively. This experiment taught that no matter how eager the people’s willingness to do at their best in daily works, it is still dependant on the nature of system within the company.
b. Airplane experiment : the importance of communication, strategic planning, empower and involve people, trust, and leadership. Focus on solution and neglect on defining the problems initially could be the source of failure. Always involving all members of the team to share ideas and to find the solution together better than a dictatorship which can lead to miscommunication. It should be noted that brilliant ideas do not always come from those who is smart, superb and experienced.
c. Helicopter experiment : by using the Taguchi model on how to improve the product or process quality by using the cost and resources as minimum as we can. By using the orthogonal array, we calculate and analyze the best composition, then make an experiment using the new design of the product to tested whether the Taguchi method affects the quality improvement of the product/process or not.
d. Rugby experiment : how to solve the problem using teamwork, the importance of leadership, trust and the involvement of every member simultaneously to give the best support in order to achieve the best performance.
2. One characteristic feature of six sigma is the belt hierarchy, such as yellow, green, black and master black. Each ‘belt’ has their task and role. Therefore, the success implementation of six sigma really depends on a few things. The senior management vision and the commitment as a basic foundation are essential. It is shown from the role allocation of six sigma players which required a certain leadership model to be conditioned. Also, it takes a sufficiently qualified human resources to create a six sigma players, that should have a commitment and highly motivated and supported to implement the six sigma.
3. From the online learning that has been provided by PMI was really helpful to give me some understandings of how to implement DMAIC methods systematically in a daily work-field situation, tools to be used and how to assign the appropriate role and task of each person in a project to be succeeded.
