Answer first

What do I do with a stuck major business decision?

A stuck major decision has an unnamed controlling element from capital, control, ownership, authority, or consequence. Name it; the decision moves. More information rarely closes a stuck decision. The work is structural, not informational.

Step one: stop adding information. If the decision has been open for four weeks and more data is not closing it, the missing piece is not data. It is the controlling element.

Step two: write down the visible decision and the unspoken decision underneath it. They are often different. The visible decision is a symptom; the unspoken one is what must close.

Step three: test which of the five elements is the lock. Capital (does the call hinge on money). Control (does it hinge on who decides next). Ownership (does it hinge on who has the stake). Authority (does it hinge on rights). Consequence (does it hinge on a downstream cost that has not been named).
