Understanding MTBF: Mean Time Between Failures (MTBF): A reliability metric that estimates the average time between successive failures of a device or system. Calculation and Importance: Calculation: MTBF is calculated as the total operational time divided by the number of failures during that period. Usage: Used by manufacturers and engineers to predict the lifespan and reliability of a device, helping in maintenance planning and lifecycle management.
