Do you have a Defect Tracking process and, if so, do you track defects within SDP?

We currently handle SDLC management outside of SDP, but we don't have a great hand-off or tracking mechanism going into two systems.

We would like to track all of our work in SDP for reporting purposes, but can anyone suggest a method for handling the Defect Management Lifecycle as it pertains to the following:

1. Where Defects are logged and stored when they aren't brought in through the support lifecycle.

2. Work logged against a ticket leading up to the point of defect detection (that is, do you do the work under a task of the problem, within the problem itself, etc?

3. When a defect is detected and needs to be tracked but isn't going to be closed with the Problem ticket (ie., you are implementing a Change Request that resolves the problem but doesn't actually correct the defect), how do you maintain and follow the defect?

Thanks,

Adam
