Building Your Octagon: Strategic Domain Selection
Not all domain combinations create equal value. The octagon must be designed, not randomly assembled. These are your primary identity—the domains where you have deepest expertise, strongest credibility, and clearest track record. Typically developed over 10+ years of focused work. Core domains are where you can operate without AI support if needed. You have genuine intuition, can recognize quality instantly, and understand the domain's history, debates, and trajectories.
Key Components
The Intersection Math
Each intersection is a potential source of unique insight, solution, or
value-creation
opportunity. This is where differentiation lives—not in any single domain, but in the combinations that only you can make.

The Three Domain Layers
Layer 1: Core Domains (2-3)
These are your primary identity—the domains where you have deepest expertise, strongest credibility, and clearest track record. Typically developed over 10+ years of focused work.
Core domains are where you can operate without AI support if needed. You have genuine intuition, can recognize quality instantly, and understand the domain’s history, debates, and trajectories.
Questions to identify core domains:
- Where have you spent most of your working hours over the past decade?
- In which fields do people seek your advice?
- Where can you spot mistakes that others miss?
Layer 2: Adjacent Domains (2-3)
Natural extensions of your core—domains with clear connections, shared vocabulary, or complementary problems. Typically developed through 3-5 years of working knowledge.
AI bridges your knowledge gaps, helping you operate at a higher level than your raw expertise would allow.
Questions to identify adjacent domains:
- Which fields do your core domains naturally touch?
- Where have you collaborated successfully with specialists?
- What domains share frameworks or principles with your core?
Layer 3: Frontier Domains (2-3)
Strategic expansions—domains you’re actively learning, where emerging opportunities exist. Typically 1-3 years of active development.
Frontier domains are where AI is essential. You’re building competence, not exercising it.
Questions to identify frontier domains:
- Where are the most valuable unexplored intersections with your core?
- What domains are rising in importance for your work?
- Where do you need capability that you currently lack?
The Intersection Math
| Domains | Intersections |
|---|
| 2 domains | 1 intersection |
| 3 domains | 3 intersections |
| 4 domains | 6 intersections |
| 5 domains | 10 intersections |
| 6 domains | 15 intersections |
| 7 domains | 21 intersections |
| 8 domains | 28 intersections |
Each intersection is a potential source of unique insight, solution, or value-creation opportunity. This is where differentiation lives—not in any single domain, but in the combinations that only you can make.
Example: The Business Engineer Octagon
- Core: Strategy, Business Analysis, Writing
- Adjacent: AI/Technology, Data Analysis, Marketing
- Frontier: Design Thinking, Finance
This octagon creates unique value at intersections like strategy-AI, business-design, and data-writing.
