Software maintenance phase<\/p>\n

A student asked: \u201cThe software development lifecycle often mention maintenance phase but few people talk about this phase. What happen in the maintenance phase? Please advice.<\/p>\n

Answer: After the software product is done and released to users, it often requires some maintenance to ensure that it operates accordingly. During the maintenance phase, software developers continue to issue software patches to address minor changes, to correct minor bugs in the software, or to resolve certain potential security issues. Throughout the maintenance phase, developers continue to work on issues that are discovered by users to improve software performance or to add additional functionality to the software.<\/p>\n

Software maintenance phase are typically performed by some developers remain after the project is completed because they are familiar with the software. The maintenance phase is also the place where company put new hires to work so they can learn more about the way company operate before allowing them to work on new project. The maintenance phase is the longest phase of all phases of the software life cycle because the software remains in operation until they become obsolete due to changes in a user’s needs or until the cost of maintaining the software becomes too high. As new technology is created, certain software becomes obsolete and too costly to maintain so companies begin develop new software to replace the existing software.<\/p>\n

Most commercially available software programs are regularly updated using downloads available through the company\u2019s online support site. System operators download updates as they are released and install these to ensure continued performance of the software in accordance with the original design specifications.<\/p>\n
