Group size matters more than you think. A team of 12 plays differently than a company of 80. For smaller groups (8 to 20), a single session with a coach and round-robin tournament works perfectly. Everyone plays everyone. For mid-size groups (20 to 60), you'll want multiple courts running simultaneously with a structured rotation so nobody's sitting idle. For large groups (60 to 150), plan a tournament format with brackets, a lounge area for networking between matches, and consider adding catering.
