Description: Maintainability refers to the ease with which a software system can be modified to correct faults, improve performance, or adapt to a changed environment. This concept is fundamental in software development, as maintainable code allows developers to make changes efficiently and with a lower risk of introducing new errors. Maintainability is influenced by several factors, including code clarity, its structure, and associated documentation. Clean code, which follows design principles and best practices, is easier to understand and modify. Code review is a practice that helps identify maintainability issues before the code is integrated into the main codebase, allowing teams to detect and correct design or implementation problems. Refactoring, on the other hand, is the process of restructuring existing code without changing its external functionality, improving its readability and reducing complexity. In summary, maintainability is a critical aspect that directly impacts software quality and the efficiency of the development team throughout the product lifecycle.
