Operations Based on STAMP

Applying the basic principles of STAMP to operations means that, like development, the goal during operations is enforcement of the safety constraints, this time on the operating system rather than in its design. Specific responsibilities and control actions required during operations are outlined in chapter 13.

In a traditional System Safety program, much of this information is found in or can be derived from the hazard log, but it needs to be pulled out and provided in a form that makes it easy to locate and use in operations. Recording design rationale and assumptions in intent specifications allows using that information both as the criteria under which enforcement of the safety constraints is predicated and in the inevitable upgrades and changes that will need to be made during operations. Chapter 10 shows how to identify and record the necessary information.
