The problem
Internal documentation fails in the same way every time. People write many pages and file them correctly. But no one knows which pages helped. No one knows which subjects stopped the readers.
The reasoning
We do not treat documentation as a store of pages. We treat it as a demand to measure. Each page asks two questions. Did this page help you? Do you want a live session on this subject? The answers decide the programme. The opinion of the writer does not.
The effect
The demand decides the programme of the live sessions. A page that no one reads becomes visible, and it can leave the maintenance list.
