You can capitalise the words "team", "practice" or "discipline" if it forms part of a name. For example, Team Awesome, the Design Practice, or the Marketing Team.

You shouldn't capitalise it if it doesn't form part of a name. For example:

• I'll hand the documents over to the other team
• Have you met our team of marketers?
• I see there's lots of good work going on in your practice.
• Will anyone from your discipline be joining?
• We're thinking of forming some sort of separate graphic design team.

We capitalise PEG names as though they are proper nouns. For example, the Savings and Administration PEG. Or the Retirement and Member Payments (RAMP) PEG.
