Quality control mechanisms

* Centralized system
- For quality control and assurance of quality
- Quality control independent of production
- Authority and independence of quality manager
- Effectively insulated from commercial pressures
- Quality control is in isolation from production
- Precluded in planning of procedures for prevention of defects
- Tend to be expensive

* De-centralized system
- Responsibility on workers
- Production manager develops plans, and routines for inspection and testing
- Inspection and testing conducted by production staff with defined and documented control programs
- Independent quality assurance manager
