What you actually have
The descent from contracted hours to hours available for planned work, line by line.
Gross, Net and the Descent Between Them
The descent from contracted hours to hours available for planned work, the six deductions that make it up, and why the total is always a surprise the first time.
Leave, Which Is Knowable
The one deduction that can be known rather than estimated, the three ways plans get it wrong anyway, and what to do about leave that has not been booked yet.
Sickness as a Rate, Not a Prediction
How to include absence in a capacity account without making a claim about any individual, which rate to use, and why the team figure is the only usable one.
Training, Statutory Time and the Centrally Booked
The deductions booked by somebody other than the planner, why they are invisible until they happen, and the calendar that makes them visible a quarter early.
Support, Interrupts and the Hours Nobody Books
The largest deduction nobody measures, how to measure it in a fortnight, and why the answer should change the plan rather than the people.
The Ramp: Joiners, Leavers and the Months Between
Why a new person is not capacity on their start date, how to put the ramp in the account, and the leaver effect that is larger than the joiner one.
What Net Capacity Actually Means in a Plan
The single number the supply side produces, what it does and does not entitle anybody to assume, and the three tests it should pass before it is published.
