Answer to Question 1
Configuration management is the process of assuring that only authorized changes are made to a system. When system maintenance is required, maintenance personnel check out the baseline modules from a system librarian. The system librarian controls the checking out and checking in of baseline modules for a system when a system is being developed or maintained.
Answer to Question 2
There are various types of maintenance requestssome correct minor or severe defects in the systems, whereas others improve or extend system functionality. From a management perspective, a key issue is deciding which requests to perform and which to ignore. Because some requests will be more critical than others, some method of prioritizing requests must be determined. First, you must determine the type of request. If, for example, the request is an errorthat is, a corrective maintenance requestthen the flowchart shows that the request is placed in the queue of tasks waiting to be performed on the system. For an error of high severity, repairs to remove it must be made as soon as possible. If, however, the error is considered nonsevere, then the change request can be categorized and prioritized based upon its type and relative importance.
