Techniques for prioritizing change requests and collecting data that can be used to monitor performance.
Configure a step for requests to be reviewed to decide which ones will be implemented. The Change Management template available in Tracker has an approval step where a request is assigned to a group. There are other ways to set up this step. For example, requests can be routed to a specific approver by department, product or request type.

Track Time Spent
Track the amount of time spent implementing a change, then run reports to dissect the data. Check out this blog post for details.
Set up a User Pulldown field to capture who approved or implemented each change. This allows you to generate performance metrics. This blog post explains how to set this up.
