Foolproofing and quality feedback: keys of process-based management

Two techniques are used to investigate software process human error prevention methods. One imports useful technologies from other engineering fields, e.g., the relations between operation methods and human errors were investigated for hardware production processes, and foolproofing process methods were systematized to prevent human errors. The other technique develops new methods based on quality feedback, where processes are improved through cause-effect analysis of empirical errors. The paper discusses establishing error-free software processes using these foolproofing and quality feedback methods
