The six sigma is the way that helps to solve the problem in the process in both of service and manufacturing. Moreover, it supports the organisation to be continuous improvement also. In the industry, it assists to improve in both of organisation capability and product quality.
There are several methods for applying the six sigma. First, select the priority which is the biggest negative impact. After that, creating the project charter to understand the problem and forming the team which has a variety of function which involves with that problem or process. We should define the SIPOC. This could help to provide the common view of process and problem. Furthermore, we should find the special cause by using control chart and find the root cause by fishbone diagram and see the significant cause by pareto.
When we can reduce the variation in the process. We could apply DOE (Design of Experiment) to find the optimisation factor which can produce the product in the good way. It could be used by determining the significant factor with the team and see the relationship between the factor by using the result of the experiment and finding the average of each factor to see the optimum point of product. In addition, we should define the action plan to implement, set the standard procedure and monitoring the process.
It could be seen that the six sigma is an important method that could make the company success in the business by facilitating to develop the quality of product, save the company expenditure and design the optimum process.
