Six sigma, distribution and possibility
- There are two method to describe the process.
- Traditional method using the maximum, minimum and range value to describe the process. Process manufacturing do not know when the process will excess the maximum or minimum (error or defect). Therefore, the range, maximum and minimum value do not give idea on the process.
- So, process manufacturing expert develop measurement scale upon which improvement / performance can be gauged which is possibility. And six sigma is the methodology that provides standardized problem-solving tools improvement.
- Distribution and possibility
- What is process sigma about?
- Process sigma is a possibility, a possibility that error/defect occur in the manufacturing process.
- Necessary to achieve six sigma?
- It depends on the customer requirement. The specification provided by customer directly affect the process sigma.
- How many sigma are required in the manufacturing process?
- It depends on the customer requirement. Six sigma company will provide the requirement on either Cpk or PPM to the supplier.
