Hypothesis Tree

A hypothesis tree is your Day-1 best guess, structured so you can disprove it fast. Issue trees decompose the question; hypothesis trees commit to an answer and tell you what to go test.

The McKinsey discipline: don't start work without a hypothesis. Otherwise you research forever, find nothing surprising, and produce a "comprehensive overview" no one acts on.


Issue tree vs. hypothesis tree

Issue Tree Hypothesis Tree
Top The question The answer (your guess)
Branches Sub-questions (MECE problem space) Sub-claims that, if true, prove the top claim
Bottom Areas to investigate Specific tests that would kill the claim
Use when You don't know what matters yet You have a strong prior and want to test it efficiently
Risk if skipped You miss a dimension You waste 6 weeks on analysis that doesn't move conviction

Both belong in the consultant toolkit. Issue tree first (frame the space), hypothesis tree second (commit and test). Skipping the hypothesis tree is the #1 reason strategy work takes 3x longer than it should.
