Methodology

In this study, it has reviewed the literature to examine the relationship between software maintenance practices and software quality as well as the effects of software maintenance expenditures and timelines on software development. It has looked through a variety of sources, including online databases like IEEE Xplore, ResearchGate, and Google Scholar, to find pertinent research papers, books, and conference proceedings on software maintenance and software quality. To focus the search, it has added terms like software development, software quality, and maintenance costs. Following a preliminary inspection of the search results, the chosen papers are further assessed considering their relevance to our study goals. Studies that were authored in English and released between 1990 and 2021 were selected. Studies unrelated to software maintenance and software quality or not pertinent to the study goals were excluded.
Moreover, the chosen papers are analyzed to determine major themes and conclusions about software maintenance practices, software quality, and the effect of software maintenance budgets and schedules on software development. To synthesize the data from the chosen studies and make judgments regarding the study issues, a qualitative methodology is adopted. To approve the viability of the investigation results, a few case studies are investigated and examined included within the chosen to inquire about articles. This case is used considers demonstrating the key themes and discoveries of our investigation and to supply real-world illustrations of software support methods and their effect on its quality and development.
