Hmm, your solution is to create a kind of resilient workflow...

Just as an engineer would do when programming a procedure\script

So, not much difference between this an actually creating a procedure\script.

Th advantage of the latter is that predictability staggers: less room for the procedure to go the wrong path, better checks and escapes when things go wrong.

And: the 'drawing board' should always include more than just the happy flow!
