PFMEA : It provides the project team with frame work to identify potential failure modes in the process and their effects on the process customers. PFMEA can be used in a Lean Six Sigma DMAIC project in the following phases:
Define: We can have a initial understanding of the potential failures that may have caused the deterioration in the bottom line of the project and come up with an expected timeline for project completion. (Given that the goal and scope supports guesswork)
Analyze: It pretty direct, it helps in understanding the root causes of the problem.
Control: Including PFMEA in control plan will help the line operators to mitigate the already occurred or potential failures.
