In this video, Dr. Richard Chua explains how to confirm and display the improved process capability during Six Sigma projects.
- Your project improvements have been implemented…and the process owners and operators are running…the improved process under normal conditions.…Now you want to confirm and display the improved…process capability.…Let's say your project was supposed to reduce…the defect rate of products or transactions…such as invoices or maybe the project…was supposed to reduce the mean and the variance…of processing times.…You need to know did that occur?…How much improvement was achieved?…Did process capability improve?…Did a sigma level improve between pre-project…and post-project performance?…This will help you quantify the operational benefits…and also help the finance team quantify…the benefits in monetary terms.…
Also showcasing improvements in process capability…and operational and financial benefits…is a great way to gain commitment and buy-in…for future six sigma projects.…So whether it's discreet data such as defect rates…or continuous data such as processing times,…Minitab can help you display the improved…process capability.…
