A: The four main types of software maintenance categories are:

1. Corrective maintenance: Core software maintenance processes that fix bugs,

2. Adaptive maintenance: Performance-based maintenance of a more technical nature that focuses on upgrading operating systems, cloud services or frameworks,

3. Perfective maintenance: Software maintenance that upgrades application functionality depending on data or customer feedback,

4. Preventive maintenance: Takes a proactive stance to identify and fix security loopholes, or to resolve any technical debt.
A: The biggest challenges surrounding software maintenance are due to a variety of factors, which include (but aren’t limited to) budget constraints, resource bottlenecks and increasing technical debt.

Another barrier to successful software maintenance could include the inability to prioritise pressing tasks appropriately; clients may wish to focus on perfective maintenance processes such as application enhancements, while software development teams may see urgency in resolving any long overdue technical debt.

However, working closely with a reliable IT outsourcing company that can offer regular reviews and unbiased analyses pertaining to task prioritisation can help keep all areas of software maintenance in check, so no one area stays too neglected over time.
A: Extra skills or resources aren’t required in most software maintenance projects, as software development teams themselves can facilitate the same via a CI/CD or DevOps approach. With many leading software companies having embraced Agile project management, software maintenance, as with any other change of requirement, can be smoothly integrated into existing development processes, thereby necessitating no extra skills or resources for the project.
