7.1.3 Common System Risks
At first exposure, to the lay person, there apparently is very little difference between the disciplines of
reliability and system safety, or any other system engineering practice like quality assurance,
maintainability, survivability, security, logistics, human factors, and systems management. They all use
similar techniques and methods, such as Failure Modes and Effects Analysis and Fault Tree Analysis.
However, from the system engineering specialist’s viewpoint there are many different objectives to consider
and these must be in concert with the overall system objective of designing a complex system with
acceptable risks.
An important system objective should include technical risk management or operational risk management.
Further consideration should be given to the identification of system risks and how system risks equate
within specialty engineering. Risk is an expression of probable loss over a specific period of time or over a
