We are trying to encorporate our SDLC into SDP+. I'm wondering if anyone else has done this.  We would like to, in some way, separate enhancement/feature requests from support requests, but we aren't sure of the best place to make that separation.

Do other people use Category/Subcategory/Item to make this distinction?
What about using an entirely different request type (e.g. Incident, Service, Enhancement)?

Should we leave it as a service request type and put it on hold we we track SDLC through our external app (Rally)?

I understand this has reprocussions down the line for reporting and metrics/SLA timeclocks, etc.

What are you doing?

Sincerely,

Adam
