System Review:

Operational systems are quickly taken for granted. Every system requires periodic evaluation after implementation. A post-implementation review measures the system’s performance against predefined requirements. Unlike system testing, which determines where the system fails so that the necessary adjustments can be made a post-implementation review determines how well the system continues to meet performance specifications. It is after the fact after design and conversion are complete. It also provides information to determine whether major redesign is necessary. The initiating study begins with the review team, which gathers and reviews requests for evaluation. It also files discrepancy notices after the system has been accepted. Unaccepted change in the system that affects the user or system performance is a primary factor that prompts system review.

The review team prepares a formal review plan around the objective of the review, the type of evaluation to be carried out and the time schedule required.

Administrative Plan:

The review group probes the effect of the operational system on the administrative procedures on the user. The following activities are reviewed:

User objectives: This is an extremely critical area since it is possible that over time either the system fails to meet the user’s initial objectives or the user objectives change as a reflecting of changes in the organizational objectives.

Operating costs and benefits: Under the administrative plan, the cost structure of the system is closely reviewed. This includes a re-view of all costs and savings, a review and up-date of the non-cost benefits a the system and a current budget designed to manipulate the costs and savings of the system.

Personnel Requirement Plan:

This plain evaluates all activities involving system personnel and staff as they deal directly with the system. The emphasis is on productivity, morale and job satisfaction. The review group evaluates the following:
  • Personnel Performance objectives compared with current performance levels: Turnover, tardiness, and absenteeism are also evaluated. The results are documented and made available to the maintenance group.
  • Training performance: Through testing, interviews, and other data gathering techniques, the review group attempts to answer questions about the adequacy of the training materials.

Hardware Plan:

The hardware of the new system is also reviewed, including terminals, CRT screens, software programs, and the communication network. The primary target is a comparison of current performance specifications with design specifications.

Documentation Review Plan:

The reason for developing a documentation review plan is to evaluate the accuracy and completeness of the documentation compiled to date and its conformity with pre-established documentation standards. Irregularities prompt action where changes in documentation would improve the format and content.
