Here are the key steps I would take:
1. Review the interview materials from Nigel, Ed and Rajesh to understand their perspectives and any challenges they mentioned.
2. Make notes on the main issues/challenges that came up across the different interviews.
3. Compare notes with my team members to get their perspectives and consolidate our understanding.
4. Prioritize the top 3 challenges to discuss with our project manager based on importance and impact to the business.
5. Prepare bullet points to briefly summarize each challenge for our discussion.
6. Practice presenting the challenges with my team to refine our discussion and ensure we fully understand each issue.
7. Be prepared to discuss how we identified each challenge and our rationale
