To achieve continuous process improvement, your organization needs a proven method for uncovering the root cause of nonconformances. A root cause analysis (RCA) can incorporate a wide range of quality methods that ultimately help identify what, how, and why an event occurred so that you can take the necessary steps to ensure that it does not repeat. The RCA process includes four basic steps:
- Collecting relevant information about the nonconformance
- Charting the causal factors
- Pinpointing root causes
- Developing and recommending solutions or corrective actions to address the root cause
If your organization has embraced lean manufacturing principles, then you are likely ahead of the curve in producing what is needed, when it is needed. You have learned that lean techniques, when successfully implemented, can help your organization reduce waste and improve process efficiency.
