What a logic tree is.
A logic tree organizes the possible explanations for a problem into a set of hypotheses and tests. It helps a team move from a broad symptom to evidence-based next actions.
Unlike a simple checklist, the branches show why each test matters and what it rules in or out. Use clear, observable questions and let data determine which branch to investigate further.

Common questions
What is a logic tree?
A branching structure that breaks a problem into hypotheses, checks, and possible next actions.
What is the difference between a logic tree and an issue tree?
An issue tree structures a problem into analytical components. A logic tree emphasizes the reasoning and tests used to diagnose it.
Should every logic-tree branch be exclusive?
Not necessarily. Several causes can coexist, but each branch should still be distinct enough to test.
How do I use a logic tree?
Start with the symptom, add the main plausible causes, and attach evidence or a check to each branch.
