True/False Indicate whether the sentence or statement is true or false. 15. Successful, robust systems often need the most support because users want to learn the features, try all the capabilities, and discover how the system can help them perform their business functions. 16.������������� In most firms, newly hired employees are trained by IT staff members, rather than user departments. 17.������������� A help desk replaces traditional IT maintenance and support activities. 18.������� In addition to functioning as a valuable link between IT staff and users, a help desk is a central contact point for all IT maintenance activities. 19.������� The systems operation and support phase is an important component of TCO (total cost of ownership) because ongoing maintenance expenses can determine the economic life of a system. 20.������� Although the procedures for corrective maintenance and adaptive maintenance are alike, minor corrective maintenance requires more IT department resources than minor adaptive maintenance. 21.������� Requests for corrective and adaptive maintenance normally come from the IT department, while users usually initiate perfective maintenance. 22.������������� Perfective maintenance can improve system reliability. 23.������������� Two techniques that can be used in perfective maintenance are reverse engineering and reengineering. 24.������������� Programs that need a large number of maintenance changes usually are poor candidates for reengineering. 25.������� An advantage of dividing systems analysts and programmers into separate maintenance and new systems groups is that the maintenance group develops strong support skills. 26.������� All analysts feel that maintenance work is more attractive than developing a new system, which they see as boring and routine. 27.������� Many newly hired and recently promoted IT staff members sometimes are assigned to maintenance projects because their managers believe that maintenance work offers the best training experience. 28.������� If a maintenance request involves a severe problem, a system administrator either accepts or rejects the request or postpones action pending further study. 29.������� With a release methodology, even when changes would improve system efficiency or user productivity, the potential savings must wait until the next release date, which might increase operational costs. 30.������� Systems analysts use baselines as yardsticks to document features and performance during the systems development process. 31.������������� Response time is unaffected by the system design, capabilities, and processing methods. 32.������������� Of all performance measurements, response time is the one that users ignore and complain about least. 33.������������� User satisfaction seldom affects the life span of a system. 34.������� All negative feedback should be investigated and documented, because it can be the first signal of system obsolescence. 35.������� The main objective of capacity planning is to ensure that the system meets all future demands and provides effective support for business operations. 36.������� In addition to CASE tools that include system evaluation and maintenance features, systems analysts can use spreadsheet and presentation software to calculate trends, perform what-if analyses, and create attractive charts and graphs to display results. ����������������������� ����������� ����������� ����������� In which maintenance type are changes made to a system to evolve its functionality to changing business needs or technologies?In corrective maintenance, changes are made to a system to evolve its functionality to changing business needs or technologies.
