Reliability testing is a process used to evaluate how consistently a product performs under specific conditions over time. This type of testing helps identify potential failures and ensures that the product meets quality standards. It is commonly applied in various industries, including electronics, automotive, and software development. The goal of reliability testing is to determine the lifespan and durability of a product. By simulating real-world usage and environmental factors, engineers can assess how well a product will function in everyday situations. This information is crucial for improving design and ensuring customer satisfaction.
