Avoid duplicate code
Summary
The source code must not have repeated functions, methods or classes.
Description
The organization must avoid code duplication because it makes maintenance more difficult. If the same functionality is implemented in multiple places and a change is needed, developers must update each instance separately. This increases the likelihood of inconsistencies and introduces the risk of omitting a particular occurrence. In general, repeated functions or methods may lead to inconsistencies in behavior or logic across different parts of the source code.
