In my experience, a Software Development Team that comprises:

• 1 Project Manager
• 1 Tech Lead
• 1 - 2 Senior Dev
• 2 - 3 Junior Dev (Fresh grad)

Only the Tech Lead & PM (and/or Senor Dev/s) will participate in a meeting with Clients, Domain Experts, Client's technical resource.

I can think of the ff potential pitfalls:

• Important info gets lost
  1. Human error (TL/PM might forgot to disseminate info due to pressure or plain human error)
  2. Non-verbal info (maybe a presentation using a diagram presented by Domain Expert)
• Maintaining Ubiquitous language is harder to build since not all team members get to hear the non-dev persons
• Potential of creative minds are not fully realized (Personally, I am more motivated to think/explore when I am involved with these important meetings)

Advantages of this approach:

• Only one point of contact
• Less time spent on meetings?

Honestly, I am biased & against this approach. I would like to hear your opinions. Is this how you do it in your team?

Thanks in advance!
