Scope

This policy describes the periodic evaluation and review of operational computer systems. Operational systems are Ministry programs and applications where part or all of the processing is by computer.

Policy

The Ministry uses various computer systems which are vital to the Ministry's programs. To help maintain productivity, security, and proper controls, these systems must undergo a structured, comprehensive review on a regular basis.

Reason for Reviews

The productivity of computer systems may deteriorate over time as the administrative infrastructure changes and grows. Several factors may contribute, such as:

• change in Ministry priorities
• introduction of new programs
• technology becoming obsolete
• key personnel leaving the Ministry

Frequency of Reviews

The frequency of operational systems reviews depends on the particular system's importance and vulnerability. Timing is determined annually as part of the Ministry's long-range planning and projected fiscal year budget.

Generally, each major operational system is reviewed every two to three years, and each minor system is reviewed every three to four years. Regardless of whether a system is classified as major or minor, all systems will come under review at a level appropriate for that system.

Review Recommendations

Reviews will identify problems and recommend appropriate adjustments and follow-up actions, such as:

• elimination of redundancy and waste
• enhancement of system
• consolidation with other functions or systems
• feasibility study
• detailed analysis
• audit
