What is MTTR? Examples and guide to system performance

Product managers are tasked with both launching and managing products, necessitating a deep understanding of key performance indicators (KPIs) that assess a product's health and performance. System performance metrics, encompassing usability, functionality, reliability, and efficiency, are crucial tools that allow product managers to make informed decisions. Among these metrics, mean time to repair (MTTR) measures the time taken to identify and resolve product failures, aiming for lower values to reduce customer complaints. Additional metrics include mean time between failures (MTBF), which predicts failure rates and guides maintenance; mean time to acknowledge (MTTA), indicating response times to issues; and mean time to failure (MTTF), assessing product longevity. Calculating these metrics requires clear definitions of terms and the collection of relevant data, ultimately enabling product managers to enhance infrastructure, staffing, and operational procedures for long-term success.
