I'm wondering if using a Defect Suite is really necessary. For example, in agile practice, if I want to schedule a group of defects into a sprint, I'll just schedule the defects individually. What's the benefit of using an additional layer of abstraction (a.k.a. a Defect Suite) to schedule defects? Defect Suites create more work/overhead to manage. Why not schedule individual defects without using a Defect Suite? Are Defect Suites really necessary?
