This section provides the core analytical frameworks used by top-tier management consulting firms, adapted for strategic commercial execution. Each framework includes step-by-step methodology, application guidance, and cross-references to the corresponding SOPs in Section 13 and templates in Volume II.
15.1 The Consulting Problem-Solving Framework
Core Principles:
- Define the problem before solving it — Half the solution is proper framing
- Decompose to actionable components — Break complex problems into manageable pieces
- Apply the right tool to the right question — Match analytical method to problem type
- Validate with data — Every hypothesis must be testable
- Iterate rapidly — Perfect is the enemy of good; refine through feedback
15.2 Ikigai — Niche Selection Framework
Ikigai (Japanese: "reason for being") identifies the optimal consulting niche at the intersection of four questions:
| Question | Dimension | Strategic Value |
|---|---|---|
| What do you love? | Passion | Sustains motivation through challenges |
| What are you good at? | Profession/Vocation | Defensible expertise and credibility |
| What does the world need? | Mission | Market demand and relevance |
| What can you get paid for? | Profession | Revenue viability and sustainability |

15.3 Issue Trees — Structured Problem Decomposition
Issue trees break complex problems into mutually exclusive, collectively exhaustive (MECE) components. Used for market sizing, cost reduction, revenue growth, operational troubleshooting, and strategic decisions.
Example — Profitability Issue Tree: Declining Profitability → Revenue Decline (Volume / Price) + Cost Increase (Fixed / Variable)
See: SOP-CON-001 for full procedure.
15.4 MVO — Minimal Viable Offer
MVO is the smallest deliverable package that solves a client's core problem. Start small, validate, then expand.
Process: (1) Define MVO → (2) Create offering → (3) Test market message resonance → (4) Sharpen based on feedback → (5) Scale.

15.5 Backward Logic & First Principles
Backward logic starts with the desired end state and works backward to determine necessary conditions and actions.
Process: (1) Define end goal → (2) Ask "What must be true?" → (3) Identify prerequisites → (4) Repeat until current state → (5) The chain becomes the execution pathway.
10X First Principles Framework: (1) Choose dimension (speed/performance/cost) → (2) Identify business drivers → (3) Estimate driver impacts via bottom-up model → (4) Select specific changes → (5) Implement and monitor.
See: SOP-CON-006 for full 10X Framework.
15.4 The 80/20 Principle (Pareto Analysis)
80% of effects come from 20% of causes. Applied to strategy: focus resources on the few activities that drive the majority of results.
Method: (1) List elements with value metric → (2) Sort descending → (3) Calculate cumulative % → (4) Identify 80% threshold → (5) Focus resources on that segment.
15.5 Rankings — Multi-Criteria Scoring
When options cannot be compared directly, use weighted multi-criteria scoring via VLOOKUP/SUMPRODUCT.
Method: (1) Define criteria with weights → (2) Score options (1-10) → (3) SUMPRODUCT(weights, scores) → (4) Rank → (5) Sensitivity analysis.
15.6 Scenario Analysis
Scenario analysis evaluates outcomes across different possible futures rather than predicting a single outcome.
Process: (1) Identify uncertainty drivers → (2) Define 3-4 scenarios → (3) Assign probability ranges → (4) Model outcomes → (5) Identify no-regret moves → (6) Develop contingency triggers.
See: SOP-CON-002 for full procedure.
15.7 Decision Tree Analysis
Decision trees map sequential decisions with probabilistic outcomes to calculate expected value.
Expected Value: EV = Σ(Probability of Outcome × Value of Outcome) for all branches.
Cost of Waiting Analysis: Compare EV of acting now vs. delaying for more information.
See: SOP-CON-003 for full procedure.
15.8 Critical Chain Project Management
Traditional project management adds safety to each task, causing Parkinson's Law. Critical chain pools safety at the project level.
Method: (1) Build network → (2) Estimate tasks at 50% confidence → (3) Identify critical chain → (4) Pool safety into central project buffer (50%) → (5) Add feeding buffers → (6) Monitor buffer consumption.
Buffer Status: Green (<33%) = On track | Yellow (33-66%) = Watch | Red (>66%) = Corrective action.
15.9 Theory of Constraints
Every system has at least one constraint limiting throughput. Focus improvement on the constraint.
5-Step Process: (1) Identify bottleneck → (2) Exploit (maximize output) → (3) Subordinate (align to bottleneck) → (4) Elevate (invest) → (5) Repeat.
See: SOP-CON-005 for full procedure.
15.10 OEE & OLE Efficiency Metrics
OEE = Availability × Performance × Quality
World-Class OEE = 85%. Most operations run 40-60%.
Overall Labour Efficiency (OLE): Same framework for human labor. Most organizations operate at 30-60% true labor efficiency.
See: SOP-CON-004 for calculation procedure.
15.11 Decomposition of Effects / LFL Analysis
Break aggregated metrics into component drivers to identify root causes and quantify improvement levers.
Revenue Decomposition: Growth → Same-Store (Volume + Price/Mix) + New Customer (Count + Avg Value) + New Product (Offerings × Revenue).
Applications: Forecasting, one-off detection, driver-based modeling, acquisition vs. organic growth analysis.
15.12 Simulation Analysis
When analytical solutions are insufficient (complex systems, high uncertainty), use simulation to explore the decision space.
Method: (1) Define inputs → (2) Model relationships → (3) Run iterations → (4) Analyze output distribution → (5) Identify sensitivity → (6) Boundary test.
