👉 Reject engineering is a systematic approach used in the design and development process to identify and eliminate flaws or inefficiencies early on, before they become embedded in the final product. It involves intentionally creating and testing prototypes or components that are deliberately flawed to uncover design weaknesses, usability issues, or manufacturing problems. By analyzing these rejections, engineers can refine their designs, improve functionality, and ensure that the final product meets high standards of quality and performance. This proactive method helps in reducing costs, minimizing waste, and accelerating the overall development cycle by addressing issues at their root causes rather than reacting to problems after they arise.
