System Safety Analysis Techniques…A Tool for a Safe Design or a Waste 700629
If system safety analysis are to have a payoff in the design process, to assure they are not a waste, they must start in the early proposal cycle and become an integral part of the project planning and control cycle. This has been a real problem on major weapon system developments in recent years and has prevented proper implementation of the analysis effort.
The heart of the system safety program effort is embodied in the system safety analysis types described in this paper. The problem is knowing when to use these analysis to minimize the cost of implementation and to get the greatest payoff. Knowing when to use these analyses judiciously comes with experience. Appendix A describes when each type safety analysis should be performed starting with the Concept Formulation Phase thru the Operational Phase of weapon system development.
The objective of system safety analyses is to provide the data and analysis so that designers can make decisions on the acceptability of the system/subsystem design from a safety standpoint.
