Which of the following is NOT a primary technique used in Product Support Analysis (PSA)?

The correct answer identifies a technique that is not primarily associated with Product Support Analysis (PSA). Mean Time to Repair (MTTR) is a metric used in maintenance and reliability engineering to evaluate the efficiency of repair processes, measuring the average time required to repair a failed component or system. While MTTR provides valuable operational insights and can influence product support decisions, it is not a fundamental technique of PSA, which focuses more on identifying and analyzing the various support elements necessary to ensure the effective operation of a system over its life cycle.

In contrast, Root Cause Analysis, Failure Mode Effects Analysis, and Life Cycle Cost Analysis are integral to PSA. Root Cause Analysis is employed to identify the underlying reasons for failures, enabling the development of effective support strategies. Failure Mode Effects Analysis proactively evaluates potential failure modes and their effects to improve design and reliability. Life Cycle Cost Analysis helps in understanding the total cost of ownership throughout the system’s life cycle, informing support strategies that aim to optimize resource allocation and system performance. Each of these techniques addresses the concepts of reliability, maintainability, and sustainability, which are essential for effective product support.
