Plan-Do-Study-Act (P-D-S-A) |
Employs cycles of planning (P), small scale pilot testing (D), analysis of test results and lessons learned (S), followed by incorporation and maintenance of new processes into practice (A) |
Useful when resources and time are limited and rapid stepwise improvement is desired |
Lean method |
Seeks to increase efficiency and reduce waste by excluding all processes, steps, or inputs that fail to contribute value to the end product |
Useful when existing practices are deemed to be inefficient and cumbersome, with bottlenecks and excessive rework |
Employs collaborative team input and process revision through value stream mapping |
Six Sigma method |
Intensively data driven approach to minimizing variation and thereby reducing defects or errors to improve quality |
Use a cyclic approach referred to as the Define-Measure-Analyze-Improve-Control method |
Employs more rigorous analytical tools and process control charting under the guidance of local experts |
Especially appropriate for repetitive high frequency processes |
