Effort Estimation Techniques Questions

Techniques and practices for estimating how long work will take and converting estimates into plans. Expect discussion of three point estimation, best case likely case and worst case reasoning, bottom up estimation by decomposing work into tasks, historical data and velocity-based inference, expert judgment and collaborative estimation practices, planning poker or consensus techniques, and how to refine estimates as more information becomes available. Candidates should acknowledge uncertainty, show how to incorporate contingency buffers, and explain when and why to ask engineers and subject matter experts rather than dictating numbers.
