Technical Performance Measures (TPM) should be selected for those parameters that:

• A. Are The Most Expensive To Test
• B. Are The Easiest To Measure
• C. Are Expected To Have The Highest Degree Of Risk
• D. Have No Risk

Answer: (C)

Technical Performance Measures are focused on validating the parts of a system that matter most for success and protection against major failures. The best approach is to choose TPMs for parameters that are expected to carry the highest degree of risk. Why? Because measuring and monitoring these high-risk areas gives you the clearest early signal about whether the design will meet its critical requirements. It helps you catch potential problems before they cascade into costly changes or failures later in development or operation. If you test something that isn’t risky or isn’t tied to the system’s essential performance, you’re investing effort where it yields little benefit, and you may miss the chance to reduce real uncertainty in the parts that truly matter. Conversely, focusing TPMs on high-risk parameters ensures testing resources are allocated where they will most improve confidence and reduce overall project risk. For example, in a propulsion subsystem, TPMs would target the parameters that most influence safety and performance under expected operating conditions, rather than on mundane, low-risk data that won’t significantly impact outcomes.
