This document summarizes 9 use cases for characterizing component feedback to improve system design and manufacturing. It provides a map and descriptions of the use cases, which focus on areas like failure analysis, life cycle cost modeling, automated data collection, and using historical data to predict outcomes. The use cases are at different stages, with some already completed and others planned for future years.
