Framework & Instructions

Step 1: Define the Problem

  • Problem Statement: What exactly are we trying to solve?
  • Constraints: What are the limitations or boundaries?
  • Dependencies: What must happen first or in parallel?
  • Decision Makers: Who needs to be aligned?
  • Success Criteria: How will we measure success?
  • Time Frame: What's the deadline or urgency?

    Step 2: Disaggregate Using Logic Trees

  • Create MECE Structure: Mutually Exclusive, Collectively Exhaustive breakdown
  • Identify Key Drivers: What are the main components of the problem?
  • Build Logic Tree: Visual breakdown of problem into manageable parts
  • Validate Completeness: Ensure nothing important is missed

    Step 3: Prioritize Using Impact-Effort Matrix

  • Assess Impact: How big is the lever's effect on the outcome?
  • Assess Effort: How easy is it to move that lever?
  • Focus on Quick Wins: High impact, low effort areas
  • Identify Critical Path: Must-do items regardless of difficulty

    Step 4: Create Work Plan

  • Define Analysis: What specific analyses need to be done?
  • Assign Owners: Who is responsible for each workstream?
  • Set Timelines: When will each deliverable be ready?
  • Determine Precision Level: How thorough does analysis need to be?
  • Plan Dependencies: What needs to happen in what order?

    Step 5: Conduct Analysis

  • Start with Heuristics: Simple rules of thumb and summary statistics
  • Use Right Tool: A/B testing, exploratory data analysis, or models
  • Validate Data Quality: Is the data accurate and complete?
  • Test Assumptions: Challenge your hypotheses rigorously
  • Avoid Over-Engineering: Don't build complex models unnecessarily

    Step 6: Synthesize into a Story

  • Build Pyramid Structure: Key insight supported by data points
  • Create Clear Narrative: What should we do and why?
  • Support with Evidence: Data-backed arguments for each point
  • Make Actionable: Clear recommendations with rationale
  • Consider Stakeholders: Address concerns and build buy-in

    Step 7: Monitor and Evaluate

  • Track Implementation: Is the solution being executed?
  • Measure Impact: Are we achieving the desired outcomes?
  • Adjust Course: Make changes based on results
  • Document Learnings: What worked, what didn't, and why?

    Prioritization Matrix

    High Impact, Easy to Change (Quick Wins)

  • Immediate actions with big results
  • Low-hanging fruit
  • Build momentum early

    High Impact, Hard to Change (Critical Path)

  • Must-do items requiring significant effort
  • May need more resources or time
  • Don't delay on these

    Low Impact, Easy to Change (Fill-ins)

  • Nice to have items
  • Do during slack time
  • Incremental improvements

    Low Impact, Hard to Change (Avoid)

  • Don't waste time here
  • Distractions from real priorities
  • Defer or eliminate

    Storytelling Structure (Pyramid Principle)

    Governing Thought: [One sentence summary of recommendation]

    Supporting Arguments:

  • [Major point 1 with evidence]
  • [Major point 2 with evidence]
  • [Major point 3 with evidence]

    Supporting Data:

  • For each major point, include:
  • - Specific numbers or facts

    - Examples or case studies

    - Qualitative insights

    Recommendation:

  • [Specific action to take]
  • [Why this action]
  • [Expected outcome]
