Maintenance Tasks System Maintenance System maintenance is the process of refining the system to make sure it continues to meet business needs. Over a system’s lifetime, more money and effort are devoted to system maintenance than to the initial development of the system, simply because a system continues to change and evolve as it is used. Maintenance Tasks The systems support and security phase is an important component of TCO (total cost of ownership) because ongoing maintenance expenses can determine the economic life of a system. Maintenance expenses vary significantly during the system’s operational life and include spending to support maintenance activities. Maintenance activities include changing programs, procedures, or documentation to ensure correct system performance; adapting the system to changing requirements; and making the system operate more efficiently. Those needs are met by corrective, adaptive, perfective, and preventive maintenance. Four Types of Maintenance Tasks 1.Corrective Maintenance -performed to fix errors 2.Adaptive Maintenance -adds new capability and enhancements 3.Perfective Maintenance -improves efficiency 4.Preventive Maintenance -Reduces the possibility of future system failure Maintenance Expenses usually are high when a system is implemented… Because problems must be detected, investigated, and resolved by corrective maintenance. Once the system becomes stable, costs usually remain low and involve minor adaptive maintenance. Eventually, both adaptive and perfective maintenance activities increase in a dynamic business environment. Which type of maintenance involves changing an operational system to make it more efficient reliable or maintainable?Perfective maintenance refers to changes made to an information system in order to add new features or to improve the processing performance. It's involves changing an operational system to make it more efficient, effective and reliable.
When corrective action Cannot occur immediately?When corrective action cannot occur immediately, users appreciate feedback from the system administrator and should be kept informed of any decisions or actions that affect their maintenance requests. Retention periods can be a specific number of months or years, depending on legal requirements and company policy.
Is a process that monitors current activity and performance levels anticipates future activity and forecasts the resources needed to provide desired levels of service?Reorganizing ANSWER: b RATIONALE: Capacity planning is a process that monitors current activity and performance levels, anticipates future activity, and forecasts the resources needed to provide desired levels of service.
When a maintenance release methodology is used all changes critical and noncritical?Using a release methodology reduces the documentation burden. When a maintenance release methodology is used, all changes, critical and noncritical, are implemented consecutively as they arrive.
