Issue Tree Generator

Overview

The Issue Tree Generator skill provides specialized capabilities for creating and validating issue trees used in structured problem solving. This skill enables hypothesis-driven analysis through proper decomposition of complex problems, MECE validation, hypothesis tracking, and synthesis of findings.

Capabilities

Issue Tree Creation

• Create issue trees from problem statements
• Decompose complex problems into sub-issues
• Generate multiple levels of decomposition
• Apply standard issue tree frameworks

MECE Structure Validation

• Validate MECE structure (Mutually Exclusive, Collectively Exhaustive)
• Identify overlapping branches
• Detect missing branches
• Score MECE compliance

Hypothesis Tree Generation

• Generate hypothesis trees from issue trees
• Convert issues into testable hypotheses
• Create null and alternative hypotheses
• Link hypotheses to data requirements

Hypothesis Testing Tracking

• Track hypothesis testing progress
• Record test results and evidence
• Update hypothesis status (proved/disproved/inconclusive)
• Calculate testing completion percentage

Evidence Linking

• Link evidence to hypotheses
• Document evidence sources
• Rate evidence strength
• Track evidence gaps

Synthesis Generation

• Generate synthesis from proved/disproved hypotheses
• Build argument chains from evidence
• Create recommendation frameworks
• Develop "so what" statements

Visual Tree Export

• Export to visual tree diagrams
• Generate Markdown tree structures
• Create hierarchical outlines
• Support multiple visualization formats

Usage

Create Issue Tree

Create an issue tree for this problem:
[Problem statement]

Decompose to at least 3 levels with MECE validation.

Validate MECE

Validate the MECE structure of this issue tree:
[Issue tree structure]

Identify overlaps and gaps.

Generate Hypotheses

Generate hypotheses from this issue tree:
[Issue tree structure]

Create testable hypotheses with data requirements.

Synthesize Findings

Synthesize findings from these hypothesis test results:
[Hypothesis results with evidence]

Build recommendations from proved hypotheses.

Hypothesis Status Tracking

Status	Definition
Untested	Hypothesis identified, not yet tested
In Progress	Data collection/analysis underway
Proved	Evidence supports hypothesis
Disproved	Evidence refutes hypothesis
Inconclusive	Insufficient evidence either way

Evidence Strength Ratings

Rating	Description
Strong	Multiple reliable sources, quantitative data
Moderate	Some reliable sources, mixed data
Weak	Limited sources, primarily qualitative
Anecdotal	Single source, opinion-based

MECE Validation Checklist

• Each branch addresses a distinct aspect
• No overlap in definitions between branches
• All possibilities are covered
• Branches are at consistent level of detail
• Same logic applies at each level

Synthesis Framework

1. What we found: Key findings from analysis
2. So what: Implications of findings
3. Now what: Recommended actions
