What is Split Solve?

Split Solve is a structured problem-solving methodology designed for manufacturing environments. It guides teams from an unclear problem through systematic decomposition to confident root cause identification using MECE (Mutually Exclusive, Collectively Exhaustive) splits.

Use the interactive tool below to work through all three phases: Define your problem, Split it into MECE branches, and Understand the root causes. Your progress is saved automatically in your browser.

MECE Split Rules

The power of Split Solve comes from enforcing MECE discipline at every level:

RuleWhat it meansWhy it matters
Mutually Exclusive No overlap between branches Prevents double-counting effort on the same cause
Collectively Exhaustive All possibilities covered Ensures the true root cause cannot hide outside the tree
Measurable Each branch can be confirmed with data Keeps analysis objective, not opinion-based
Functional or Geographic Splits follow logical system boundaries Aligns investigation with how the system actually works

Apply Split Solve to your problems
