    A SYSTEMATIC LITERATURE REVIEW ON AGILE SOFTWARE MAINTENANCE
    (UMT, Lahore, 2021) IMRAN ASHRAF CHUHDARY
    Software maintenance is unarguably the lengthiest and most cost phase in the lifetime of software. But in most of the literature, emphasis has been only on exploration of software development in the context of classic or agile methods. Waterfall based methodologies work on the principle of sequential flow of work while agile methods are iterative and incremental in nature. The research has shown that use of agile methods help producing software, lesser in cost and better in quality. Certain statistics are available to support the claim that agile methods have reduced cost of software development from 20 to 30 percent. The reason behind is iterative and incremental nature of agile methods that involve the user stakeholders during the whole SDLC process. But not much attention has been paid in literature to see the impact of agile methods on software maintenance. This study demonstrates several papers that are very useful in depicting the state of software maintenance by using agile methodologies. Almost 30 papers will be studied and investigated which are conducted after the introduction of agile for software maintenance. It can be concluded that by opting agile methodology for software maintenance there is a visible improvement in the context of maintenance cost and quality of the software. This study will also help the professionals to identify the context of using agile methodology and its pros and cons, types of agile frameworks and the integration between them.
