- Selecting correct project is important for getting substantial benefits of Six Sigma. Some typical outlines of Six Sigma SCM projects are:
- Reducing cost without increasing delivery time.
- Improving supplier’s product quality.
- Reducing delivery time.
- All the areas of supply chain including procurement, distribution channel, ware houses to be studied for existing process.
- Collecting VOC from correct size of sample is important.
- Analyze VOC to find X’s using QFD.
- Do benchmarking using some existing successful supply chain model.
- Propose improved process flow chart.
- Implement the new process.
