A literature review for measuring maintainability of code clone

Software organizations face constant pressure due to stakeholder requirements and the increasing complexity of software systems. This complexity, combined with defects in code quality failures, can pose risks To ensure is understood before maintenance, developers must spend over 60% their time modifying improving quality, which costly. study examines impact refactoring activities on maintainability by reviewing relevant research explaining key terms. The finds that enhance specific characteristics, including maintainability, understandability, testability. also identifies important factors should be considered when developing tools. Refactoring enables improvement without altering program behavior applied multiple times source code.
