Module 12: Managing System Support and Security

After the system is implemented the systems support and security phase that
covers the period from the implementation of an information system until the
system no longer in use begins. At this point, the systems analyst's primary
participation with a system is to manage and solve user support.

Maintenance includes changes to correct errors among other things. There are
different levels of maintenance that have different attributes. Adaptive
maintenance fulfills new systems requirements, and perfective maintenance
increases efficiency. When adaptive and perfective maintenance occur often they
are called enhancements. Preventive maintenance is done to avoid future
problems.

The maintenance process resembles the systems development life cycle. A
request for maintenance work is submitted and evaluated. If it is accepted, the
request scheduled. The maintenance team can then go through the steps to
solve the problem. Corrective maintenance projects occur when users report
problems. There should be standard maintenance procedures in place to
address minor errors, but work often begins immediately when users report major
errors. However, adaptive, perfective, and preventive maintenance projects
always follow a standard maintenance procedure.

There will be intense competition in the future. To face this challenge, IT priorities
should be the safety and security of corporate operations, environmental
concerns, and bottom-line cost. An IT professional should have a strategic career
plan that includes long-term goals and intermediate mileposts. IT credentials and
certifications that document specific knowledge and skills are important to keep a
professional prepared.
