All notes
Everything here, grouped by subject.
Foundations
6 notesAssessment narrows uncertainty about capability. It does not remove it, and processes designed as though it does fail predictably.
Methods
8 notesThe ordering between methods is more reliable than the numbers attached to them, and it is stable across analyses.
Designing a process
7 notesEach requirement assigned to exactly one method that can assess it. Anything unassigned comes out.
Fairness
7 notesEvery additional hurdle selects on slack as well as on capability, and the people it removes have less of the first rather than less of the second.
Running it
6 notesCalibration is the highest-return hour available to most organisations, and almost nobody spends it.
Obligations
5 notesMost exposure sits in indirect discrimination: neutral requirements that disadvantage a group and cannot be justified.
Beyond hiring
6 notesInternal candidates frequently receive less assessment than external ones, which is the wrong way round.
Reference
5 notesThe end state as a checklist, twelve common failures, and where to start.
