Scenarios

Three organisations, set up from end to end.

A walkthrough teaches one task. A scenario shows a whole organisation: the parties, the places, the activities, the assessments, the transfers and the risks, built in the order they are built, with the reasoning behind each decision.

Where a decision could reasonably go another way, the alternative is stated together with what changes if you take it. These are deliberately difficult organisations, because the easy ones do not teach anything.
