THE FOUR MAINTENANCE TASKS ARE:
1.CORRECTIVE MAINTENANCE
2.ADAPTIVE MAINTENANCE
3.PERFECTIVE MAINTENANCE
4.PREVENTIVE MAINTENANCE
The four maintenance tasks used in the small business press’s in the new ARCIS are:
1.CORRECTIVE MAINTENANCE:-
The corrective maintenance diagnoses and it fix logic errors.It refers defective network cabling.The best maintenance approach is a scaled down version of the sdlc itself,where the investigation ,analysis before implementing the solution.In this requests receive a high priority and a maintenance team begins work on the problem immediately.In small business press’s new ARCIS the corrective maintenance fixes the problems and they debug the code of the program and then update the software required.
2.ADAPTIVE MAINTENANCE:-
Adaptive maintenance adds enhancements to an operational system and makes system easy.An enhancement is a new feature and this maintenance is similar as corrective maintenance.A major adaptive maintenance program is like a small business press new sls because the development method is same.And in this press this maintenance creates new reports.
3.PERFECTIVE MAINTENANCE:-
This maintenance changes the operational system to make it more efficient and reliable.It also can improve system reliability.In the small business new ARCIS ,a system is easier to maintain ,support is less costly.This maintenance is less valuable in its benefits if the press already plans to discontinue the system.In a small business press if the system uses perfective maintenance the analysts use a technique called software engineering.
4.PREVENTIVE MAINTENANCE:-
In a system ,it solves the problems,this maintenance requires analysis of areas where trouble is likely to occur.This maintenance often occurs when in an increased user satisfaction and reduced downtime.In this small business this maintenance tightens all the required cable connections.
