Phases of software maintenance life cycle

Optimization, problem fixing, removing unused functionality, and improving already existent functions are all parts of continuing software maintenance. Tech teams can use the elaborate framework given by IEEE repeatedly with their own unique activities and procedures. The major stages of the software maintenance life cycle are described by this framework as follows:

Problem identification phase: Phase one of the problem-solving process involves identifying the software modification requests and giving each one a unique identification number.
Problem analysis stage: This stage evaluates each legitimate modification request to ascertain its viability and scope.
Design phase: Based on needs provided in earlier phases, developers construct new modules that need to be replaced or modified at this stage.
Implementation phase: During the implementation phase, developers adjust the software as a whole and add specifications, new features, and code.
System test phase: During this stage, the development/testing team tests how well new modules work with the overall system.
Acceptance test phase: During acceptance testing, internal users or a third party specify and run tests on the fully integrated system.
Delivery phase: The group distributes updated software to users following a positive outcome from the acceptance testing.
