Unformatted text preview: ason is analyzed and if possible, necessary changes are incorporated in the new system to rectify it. 2. Cost Analysis. It should be analyzed whether the cost estimate done for the various phases of the project during the planning phase in the beginning match with the actual cost incurred in each phase or not. If discrepancies are found, the cost analysis will help in finding out the reasons. This type of analysis proves to be quite helpful in making correct cost estimates for the new systems that will be designed in future. 3. Time Analysis. It should be analyzed whether the time estimate done for the various phases of the project during the planning phase in the beginning match with the actual time taken in each phase or not. If discrepancies are found, the time analysis will help in finding out the reasons. This type of analysis proves to be quite helpful in making correct time estimates for the new systems that will be designed in future. 4. User Satisfaction. People are the final evaluators of any system put in operation. Hence, it should be found out whether the users are satisfied with the new system or not. How useful is the system for them? How enthusiastic are they about the service they receive? Do they receive outputs in time to take necessary action? The morale of people using or affected by a system is a good measure of the success of the system. 5. Ease of Modification. Sooner or later, all systems need to be modified due to one or more of the reasons mentioned in the next section. Thus, the ease with which a system can be modified to incorporate the suggested changes is also an important parameter to judge the quality of the system. 6. Failure Rate. Another parameter that is commonly used to judge the quality of a system is its failure rate. A system, which frequently fails cannot meet its objectives successfully and hence is of poor quality. SYSTEM MAINTENANCE No matter how good the new system is, how well it was installed, and how well it may be currently operating sooner or later it will need to be modified due to one or...
