Map who this decision lands on

A change that will affect people who are not in the room when it is made.

Map the people affected by this decision.

For each stakeholder or group:
- What they want, in their own terms rather than as I would characterise it
- What they lose, including things they value that I might not think of as losses
- How much power they have to block, slow, or quietly ignore this
- What they need to hear, and from whom, for this to go well

Then:
1. Who has been left out of my list? Look for people downstream of the change who never get consulted.
2. Where is the genuine conflict of interest, as opposed to a misunderstanding that better communication would fix?
3. Who should I talk to first, and what should I ask them rather than tell them?

The decision and who I think is affected:

Stress-testing a plan. Pre-mortems, arguing the other side, and following the consequences past the first order.
