Before any change to how the sales process behaves, a rehearsal runs the whole twenty step chain against a test record and reports what broke. It had been stopping at the second step for three days, and nothing said so, because a rehearsal nobody runs looks exactly like one that passes.
- The rehearsal did not know about a question added to the process the day before, so it never cleared that answer between runs. The test record carried a stale answer from an earlier run, which made the first step pass for the wrong reason.
- It also never attached the document that the process has required since the end of August before it will close a review step. That is what stopped the run at step two, so steps three to twenty had not actually run in three days.
- Both were repaired. The full chain now passes twenty one of twenty one steps, the count of records created comes out exact, and the test record is left clean.
- It was found only because a separate change needed proving. Nothing reports a rehearsal that is not being run.
