All notes
Everything here, set out by subject. Most people arrive with a specific situation, so the reading paths at the end may be a faster route in.
All 50 notes
Set out as an account: the subject on the left, the notes on the right. The layout is a layout, not a chart — it says nothing about which column is larger. Working that out is what several of these notes are for.
The basics
3 notes
The term covers six things that need different responses. Separating them is most of the work.
The categories
8 notes
Each taken separately, because a policy that treats them as one fails at all of them.
Both directions
6 notes
The same records answer both questions. In most measured comparisons the unpaid column is larger, and it is the one with a statutory basis behind it.
Investigation
6 notes
Four system checks before anyone is spoken to, and the four tests that distinguish a real case from an anomaly.
What works
10 notes
The technical controls come fourth, behind three things that cost nothing: slack in the rules, fixing the structural causes, and supervision.
Controls
5 notes
Each method addresses one failure and leaves the others open. Matching the method to the measured problem is the whole decision.
Legal
2 notes
Most of what decides these matters cannot be produced after the fact, and all of it is cheap to capture as habit.
Measuring
2 notes
Six measurements, each an afternoon, that between them replace every industry statistic in this subject.
What not to do
3 notes
The asks that arrive once someone has decided there is a problem, and what to offer instead of each.
Reference
5 notes
The end state as a checklist, the questions the data cannot answer, and where to start depending on your situation.
