Decision Mastery Decide With Others

Who else does this touch — and have I asked them?

Before finalising any significant decision, make three lists: who is affected, who has power to block or shape the outcome, and who has not been consulted. Anyone appearing on two or more lists needs a conversation before you commit.

Use when

A decision will change how other people work, spend, or experience something.

Avoid when

The decision is purely personal with no downstream impact on others.


Why it works

Decisions fail when affected people are surprised. Mapping power, impact, and consultation gaps surfaces resistance before it hardens.

A decision can be analytically sound and still fail because someone affected by it was surprised. The three-list exercise treats the decision as a social system, not only a logic problem. Who is affected? Who has power? Who has not been consulted? The overlap is where resistance is most likely to form. Mapping this early surfaces constraints before they turn into objections. It also gives people a chance to be heard while the decision can still absorb what they know. That is cheaper than trying to repair trust after the announcement.

Implementation Neglect: Why Analytically Perfect Decisions Fail in the Hallway
Decisions don't fail in spreadsheets. They fail in hallways, in meetings where someone says 'nobody asked me about this,' and in the quiet resistance of people who feel overlooked.
