One-way and two-way doors, blast radius, and where a person belongs

How cheap is it to undo decides where the human goes: put the person where the output cannot be undone and the blast radius is large; give them the why; let the record move the line over time. People approve 93% of permission prompts.

Decided by. Nobody yet: a candidate for Dinis to read, comment on and decide (keep, rewrite, merge, cut, article first, later, not doing it).

Note. Build or buy becomes how much it costs to undo and how mature the controls are: a narrow internal tool that a few people use and that can be switched off is a two-way door, so build it, explore, learn; a tool that touches regulated data every day is a one-way door until the controls are mature, which is where the villagers have to be in place first, yours or a partner's.

Where it goes

Chapter Direction is the scarce skill, part Direction and judgement (drafting); topic Where a person belongs: one-way doors, two-way doors and blast radius.

Other ideas proposed for the same chapter: Direction is the scarce skill: the place of highest leverage, Knowing when to stop is most of seniority, Agents decide, people answer, A budget per step, declared before anything runs, is the objective way to say good enough; the five whys move it.
