Software Maintenance : is the activity of modifying the software product after delivery ; in order to correct faults, improve performance and to improve other attributes ( attributes of a good software ) .
Software maintenance is a vital element in SDLC . Normally and more often done by the developers / or software maintainers ( of the software service provider / the software company ) .
Types of software maintenance : there were only three few years back, but present there are FOUR ( 4 ) types of software maintenance types / kinds are defined .
- Corrective Maintenance - corrective maintenance means a REACTIVE modification, done in the software product after the delivery . The purpose of corrective maintenance is to correct / or fix discovered ( or user reported ) problems in the system .
- Adaptive Maintenance - adaptive maintenance is also a modification done after delivery, in order to keep the software product usable in changing ( or changed ) environments / business environments . If this is not done properly by the time of change, business opportunities will be lost .
- Perfective Maintenance - a software should be efficient / less resource consuming / and should be easy to cope with . Perfective maintenance is done in order to improve the software performance ( after a change in the software or / the environment, the performance of the software changes ) . Also improving the maintainability is a concern .
- Preventive Maintenance - of course as it sounds, it's just PREVENTING . Preventive Maintenance is done, to detect and correct latent ( not developed ) faults before they become effective faults . This simply means the prevention of future problems .

EXTRA READING :
Software maintenance sounds like, " ONLY ERROR CORRECTING ", but IT'S NOT that . 80% of the software maintenance is NON - CORRECTIVE activities ( activities which are not used to correct faults, but for other purposes ) . However, software maintenance issues can be seen in two perspectives, one is managerial issues and the other is technical issues . Managerial issues can be alignment with customer priorities, managing the staff, estimations . Technical issues may be limited understanding, impact analysis and testing .
In software maintenance, SOFTWARE MAINTENANCE PLAN and SOFTWARE MAINTENANCE PROCESS are also KEY considerations . Software maintenance plan is the pre planning which should be very accurate ( this plan includes about user's requirement changes / or change requests, budget etc ) . Software maintenance process is the sequence of steps followed during the software maintenance process . which includes,
- Implementation Process
- Problem and modification analysis process
- Process acceptance of the modification
- The migration process
- Last maintenance process
- etc ...

What is software maintainance?
Software maintenance is an important component of software development. Maintenance involves debugging the software, and releasing periodic updates to correct problems and make the software work better.
Why is it sometimes difficult of types of software maintenance to distinguish between them?
Distinguishing between types of software maintenance can be challenging because many maintenance activities often overlap in their objectives and processes. For instance, corrective maintenance (fixing bugs) may involve modifications that also enhance functionality, blurring the lines with adaptive or perfective maintenance. Additionally, the context of changes may vary, making it hard to classify them strictly into one category. This complexity is further compounded by the continuous evolution of software, where updates often serve multiple maintenance purposes simultaneously.

Each type plays a crucial role in ensuring the long-term reliability and efficiency of software systems.
