Evidence-Based Problem Trees is a practical, facilitator-ready training toolkit that teaches professionals to structure complex business problems, develop testable hypotheses, evaluate evidence, and make defensible decisions.
Teams often create problem trees with overlapping branches, unsupported assumptions, or solutions chosen before the diagnosis is complete. This toolkit provides a disciplined approach to prevent these errors and improve analytical quality.
Who It Is For
Designed for management consultants, Lean Six Sigma practitioners, continuous improvement leaders, project managers, engineers, business analysts, and process owners. No prerequisites are required beyond basic familiarity with percentages and sampling.
What You Will Learn
Define bounded, neutral, measurable problem statements.
Build logical problem trees using part-of, AND, and OR structures.
Identify overlapping branches, gaps, and unsupported assumptions.
Formulate falsifiable hypotheses and establish evaluation criteria before reviewing data.
Classify hypotheses as Supported, Rejected, or Open based on evidence.
Translate findings into proportionate decisions while acknowledging evidence limitations.
How It Works
The seven-stage workflow covers Define, Structure, Hypothesize, Test, Prioritize, Decide, and Verify. A continuing fictional distribution-center case, involving a 14.0% rate of late or incorrect orders, demonstrates the method from baseline through evidence evaluation. Five practice exercises reinforce application and analytical judgment.
What Is Included
The primary document is a 47-slide editable PowerPoint with instructional visuals, worked examples, and participant exercises.
A Participant Workbook with eight reusable worksheets, worked examples, and exercises, an Answer Key with expected responses and a four-level quality rubric.
Important Notes
All case data are fictional and illustrative. The material is industry-neutral and contains no organization-specific proprietary framework.
