Now that you have a good background in systems safety, let’s put all that newfound knowledge to good use and do a complete analysis of a system. Pick any system you are somewhat familiar with. It can be something you work with on a daily basis or it can be something you just read that interests you. The choice is yours.
Provide a brief synopsis of your system and what it is designed to do. Then provide a complete analysis of the system from a systems safety standpoint. You can analyze the entire system if it isn’t too big or you can do a subsystem, which is a part of the whole. Your analysis should include the following:
A PHA
Impact of each item in the PHA (i.e., what can happen if it is not mitigated)
Risk Analysis Matrix
Pick at least two of the items identified in your PHA and use any of the tools we have covered to analyze them.
A detailed report to your boss: In this report be sure to provide your operating assumptions and recommendations for how to correct what you found.
Thinking in terms of the two items you picked, tell how often they should be reevaluated throughout the life cycle of the system and why.
Realize this isn’t just a narrative. Your analysis should include the applicable charts, such as a PHA, PHL, or fault tree for example. You must have some of the actual diagrams you used to make your assumptions.
