Chapter 5 Continuous Process Improvement
Create a system for constant and continuous improvement
2
Understand the Process: Variations are Major Enemies
Detecting mode (heavy dependence on inspection/testing/control): Fire fighting is not effective Preventive mode (emphasis on “do it right the first time and all the time): Use FEEDBACK to take corrective actions so that the process can be continuously improved.
3
Process Model
4
Process Improvement Strategy: Finding Cost Effective Solution
Control existing process: i.e., statistical process control (SPC) Optimize the process: i.e., design of experiment (DOE) Change the system: hardware, software and brainware New system: machine, human, materials, method
5
PDSA Cycle: Embedded in the Continuing System
Plan Do Study Act Plan again …
6
Problem Solving: A Continuous Effort
Identify problems as an opportunity Analyze the problem: to find root causes Develop optimal and cost effective solutions Implement changes: system wide Study the results: worked or not? Need adjustment? Standardize solution: Keep problems from reoccurring.
7
Six Sigma: Aim High Specification Limit Defective Rate +/- 3 sigma
0.27% (2700 ppm) +/- 4 sigma 63 ppm +/- 6 sigma 0.002 ppm (3.4 ppm if process is not centered)
