Accessible diagram transcript
Objects
- 1 · Fragmented: Unclear ownership (Providers)
- 2 · Defined: Named functions (Governance)
- 3 · Governed: Decision rights and controls (Authorities)
- 4 · Product-led: Reusable platforms and SLOs (Engineering)
- 5 · Adaptive: Measured outcomes and learning (Operations)
Directed relationships
- level-1 → level-2: clarify (handoff)
- level-2 → level-3: govern (handoff)
- level-3 → level-4: productize (handoff)
- level-4 → level-5: optimize (handoff)
When to use it
Use to structure an evidence-based maturity discussion and define a realistic next operating-model horizon.
What to challenge
- Separate accountable authority from delivery execution.
- Make every important handoff directional and reviewable.
- Treat this reference pattern as a starting point, not a prescription.
Adapt it responsibly
- Rename functions to match the organization vocabulary.
- Remove elements that are genuinely out of scope.
- Validate decision rights and handoffs with accountable stakeholders.
