PLAN-DO-CHECK-ACT CYCLE (PDCA)
Based upon work by W. A. Shewart and made popular by W. E. Deming
Goal: To optimize and improve a single process model/production line
Approach: Use techniques such as
- Feedback loops
- Statistical quality control
- Design of experiments
- Data models based upon multiple replications
Note: Any application of the process produces a large quantity of products, sufficient to generate a valid statistical model
Result: Predictive models of the relationship between process and product
