Maintainability - GCSE Computer Science Definition

Program maintainability is about how easy it is to understand, fix, and update computer programs after they’ve been written. Imagine having to fix or change a project someone else made as it is easier if the project is well-organised and clearly explained. In the same way, a maintainable program has tidy code, helpful comments, and a clear structure, making it simple for anyone to read and work on later. This is important because technology changes and errors need fixing over time, so having a maintainable program helps make sure it continues to work well in the future.
