Running a two-day pilot

Preparation the week before, including a solo rehearsal — a pilot that breaks on screen loses more credibility than not running one. Who attends and why the controller especially. Day one walks the master data asking "is this how you actually make it?"; day two executes through to the journal entries. Facilitation rules, the output that protects you for the rest of the project, and the failure mode of using your own demo data instead of theirs.
