Knowledge of customer usage of IC products is an important part of establishing accurate use conditions inputs for product reliability modeling. We present a multi-stage framework for achieving this: derive telemetry metrics; develop telemetry software; acquire users; manage and store telemetry data; perform data analytics and visualization; decide use conditions. We discuss each stage's objectives and requirements, and provide information relevant to successful implementation. Server telemetry examples are presented to elucidate the framework and its role in evaluating product reliability.
