Bathtub Curve

The Bathtub Curve is a graphical representation that illustrates the failure rates of a product over its lifecycle, characterized by three distinct phases: early failures, a period of reliability, and eventual wear-out. Initially, products experience a high failure rate due to manufacturing defects and design flaws, which decreases as these issues are resolved. Over time, however, the failure rate increases again as the product ages and components degrade, highlighting the importance of ongoing maintenance and innovation in product design and production.
