A Starter Tool of the Summit Operating System™ (Summit OS®) — to Clarify Roles, Build Accountability, and Accelerate Growth
If your business has grown beyond the point where everyone does everything, you need a structure that empowers leaders, not entangles them.
The Function Ownership Chart™ is a proprietary Summit OS® tool that helps leadership teams define who owns what — creating clear accountability, role focus, and scalable growth.
What Is the Function Ownership Chart™?
The Function Ownership Chart™ is a forward-looking organizational design framework that maps the critical leadership-level functions your business needs to reach its next stage of growth.
Unlike traditional org charts that describe reporting relationships, this chart defines accountability for outcomes.
Each function has:
- A clearly named owner (never more than one),
- 4–6 measurable outcomes they’re responsible for,
- And, any independently owned subfunctions, or subfunctions the function owner is planning to delegate in the next 6–12 months
How It Works
The Function Ownership Chart™ helps business owners and leadership teams:
- Identify all key functions in Get Work, Do Work, and Get Paid categories.
- Assign ownership for each — no shared accountability, no overlaps.
- Prepare for the next level of growth by anticipating future subfunctions.
- Clarify roles between Visionary and Operator (2IC) — the two halves of leadership that drive both strategic direction and daily execution
Used by certified Summit OS Guides™, the Function Ownership Chart™ becomes a living blueprint for building autonomy, accountability, and execution rhythm within leadership teams.
Why It Matters
Most businesses plateau not because of poor strategy but because of unclear ownership.
The Function Ownership Chart™ eliminates ambiguity by turning every executive into a “Mini-CEO™” — responsible for a domain’s outcomes and empowered to build their team and improve their playbooks.
This tool is part of the broader Summit Operating System™, a structured methodology combining 50+ proprietary worksheets and tools for empowering leadership teams to align, execute, and grow profitably.
Who Uses the Function Ownership Chart™
Hundreds of mid-market and entrepreneurial companies coached under Summit OS® use the Function Ownership Chart™ to:
- Transition from founder-led to team-driven operations,

- Create functional scoreboards that track weekly wins (WTW Scoreboard™), and
