In today's swift moving software development space there are lots of tools & services for helping a Software QA team manage their test case library. The key needs for one of these systems is to have a way to easily curate the creation, maintenance and organization of the test cases and track their execution progress over time.

Here are my questions:

1. Did you buy or build a TCM?
2. What did your company/team do?
3. What was the driving force behind your decision?

Looking forward to your insights.
