Roles and teams
Team capacity
Also calledDesign capacity, Capacity planning
The total amount of work a team can take on in a period. It is fixed, so giving more time to one activity always takes it from another.
Capacity is usually counted in people-weeks: a team of five designers has roughly 25 working days a week to spend. Planning capacity means deciding where those days go, across research, design, reviews, systems work and everything else.
The useful insight is that capacity is a budget, not a wish list. Asking a team to do more research without saying what they should do less of is not a plan.
