Reliability Engineering is a field of engineering focused on ensuring that systems, products, and processes perform consistently over time. It involves analyzing potential failures, understanding their causes, and implementing strategies to minimize risks. This discipline is crucial in industries like aerospace, automotive, and electronics, where safety and performance are paramount. The goal of reliability engineering is to enhance the lifespan and dependability of products. Techniques such as failure mode and effects analysis (FMEA) and root cause analysis are commonly used to identify weaknesses and improve design. By prioritizing reliability, companies can reduce costs associated with repairs and increase customer satisfaction.
