What should the agile team lead do?

Agile fosters a safe-to-fail environment where experimentation is encouraged. According to the PMI Agile Practice Guide (Section 5.6: Retrospectives and Process Improvement) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 7: Continuous Improvement), teams should be empowered to test new ideas and learn from outcomes, regardless of whether those experiments succeed or fail.

Option D is correct: promoting experimentation supports learning and innovation.

Option A discourages risk-taking and limits growth.

Option B creates fear and undermines psychological safety.

Option C mixes accountability with experimentation, which can discourage honest learning.
