The Owner Scope Management model.
One canonical model for the owner-accountable readiness work between capital delivery and safe, compliant operations — governed, evidenced, accepted, and improved. Industries speak it in their own language; the model underneath stays coherent.
What Owner Scope Management governs.
OSM is the discipline of governing, planning, coordinating, evidencing, accepting, and improving the owner-accountable work that brings a facility, system, or service into operation — work the owner cannot delegate to delivery teams.
Delivery completes the asset. The owner proves it can operate.
The boundary is the heart of the model. Confusing the two is how opening dates slip and readiness risk hides.
What the contractor completes
- —Substantial completion & punch list
- —Commissioning & functional testing
- —Closeout documents & as-builts
- —Beneficial / mechanical completion
What the owner must prove
- ✓Criteria met with accepted evidence
- ✓Gate authority & go/no-go decisions
- ✓Stakeholder, trial & training readiness
- ✓Handover, acceptance & stabilization
Nine phases, from criteria to realized value.
Each phase produces accepted proof that feeds the next. The lifecycle is the same in every market — only the vocabulary changes.

Define the readiness program, workstreams, and criteria the owner is accountable for.
Coordinate
Assign accountability across stakeholders, trials, risks, and issues.
Evidence
Collect and accept current proof tied to each criterion.
Gate
Classify gate authority — owner soft, regulatory hard, contractual acceptance.
Decide
Make a defensible go/no-go from accepted evidence.
Activate
Open, energize, go-live, or enter revenue service.
Transition
Transfer responsibility from delivery to operations.
Accept
Establish operational control through handover and acceptance.
Improve
Govern outcomes through stabilization and benefits realization.
The objects the model is built from.
Every CitiriOS workflow, metric, and AI answer traces back to these ontology-backed concepts.
Readiness Program
The owner-accountable scope of a launch event.
Readiness Criterion
What must be true to operate safely.
Evidence Pack
Accepted, current proof tied to criteria.
Governance Gate
Authority to approve, block, or condition.
Readiness Index
Ready Score — evidence-backed, by domain.
Activation Event
Opening, go-live, energization, RFS.
Transition Event
Cutover, move wave, handover to ops.
Operational Acceptance
Owner acceptance of operating capability.
Five levels of owner readiness maturity.
Where an owner sits today determines how much readiness risk is visible — and how defensible the next go/no-go will be.
Reactive
Spreadsheets and status meetings. Readiness is opinion, not evidence.
Repeatable
Documented checklists, but evidence and gates live in silos.
Governed
Gate authority and criteria are explicit and owned.
Evidence-driven
Decisions rest on accepted, current, traceable evidence.
Outcome-governed
Readiness drivers connect to stabilization and realized value.
