Overhaul refers to a comprehensive examination and subsequent improvement of a system, process, or product. This term is commonly used in various fields, including engineering, business, and software development. The goal of an overhaul is to enhance efficiency, performance, and reliability by identifying and addressing weaknesses or outdated components. In the automotive industry, for example, an overhaul may involve disassembling an engine, cleaning its parts, and replacing worn-out components to restore it to optimal working condition. Similarly, in software development, an overhaul might include rewriting code or updating features to improve user experience and functionality.
