Detecting Development Process Flaws during Operations

2 Detecting Development Process Flaws during Operations 

Detect safety-related flaws in the system design and in the safety control structure, hopefully before major losses, and fix them. 

Determine what was wrong in the development process that allowed the flaws to exist and improve that process to prevent the same thing from happening in the future. 

Determine whether the identified flaws in the process might have led to other vulnerabilities in the operational system. 

To accomplish these goals, a feedback control loop is needed to regularly track and assess the effectiveness of the development safety control structure and its controls. Were hazards overlooked or incorrectly assessed as unlikely or not serious Were some potential failures or design errors not included in the hazard analysis Were identified hazards inappropriately accepted rather than being fixed Were the designed controls ineffective If so, why
