Good software for your business is important, but more that that its equally important to make those working for your business for longer time.
As a definition we can say, Software maintenance is the modification of a software product after delivery to correct faults, to improve performance or other attribute.
There are a number of processes, activities and practices that are unique to maintainers like GrassDew, for example:
Transition: a controlled and coordinated sequence of activities during which a system is transferred progressively from the developer to the maintainer;
Service Level Agreements (SLAs) and specialized (domain-specific) maintenance contracts negotiated by maintainers;
Modification Request and Problem Report Help Desk: a problem-handling process used by maintainers to prioritize, documents and route the requests they receive;
In broader scale, there are four types of Software Maintenance. Most of maintenance tasks are in perfective maintenance as shown in below diagram. I will focus more on perfective maintenance in this article.
Let me give some overview of each area under each.
Corrective maintenance: Reactive modification of a software product performed after delivery to correct discovered problems.
Adaptive maintenance: Modification of a software product performed after delivery to keep a software product usable in a changed or changing environment.
Preventive maintenance: Modification of a software product after delivery to detect and correct latent faults in the software product before they become effective faults.
Perfective maintenance: Modification of a software product after delivery to improve performance or maintainability.
Five Benefits of Perfective Maintenance:
1. Extends the useful lifecycle of assets decreasing the need for capital replacements.
2. Enhances the efficiency of equipment keeping them running more efficiently and lowering power expenses.
3. Enhances the performance of assets by increasing uptime.
4. Enhances customer (internal or external) service because maintenance teams have less unplanned maintenance and can respond quicker to new problems.
5. Contributes positively to the reputation of companies
