What you will take away
  • Why the P1/P2 decision is a scoping exercise, not a blanket upgrade
  • A persona model that maps roles to plans and typically covers Plan 2 for ~45% of seats
  • A 10,000-seat benchmark: flat P2-everywhere at $624K/yr vs a persona split at $281K/yr
  • How to spot the +131% premium of buying the E5 Security add-on where standalone P2 would do
  • A 90-day rollout calendar and the levers to hold the add-on price for the EA term
