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.
Owner Scope Management is the model behind real openings — not a framework on a slide.

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
Eleven stages, from business case to realized benefit.
Each stage exits through a gate and produces accepted proof that feeds the next. The shape is shared across markets — the gates, evidence, and authority are each industry's own.
Download the full model briefStrategy & Business Case
Define operator intent, strategic objectives, and the business case, mandate, and budget for readiness.
Definition & Planning
Stand up the readiness program: ConOps, operating model, owner/delivery scope register, governance and RACI.
Design Integration
Inject operability and operator intent into design; capture requirements and the Checkpoint 0 data plan.
Delivery Coordination
Coordinate with delivery; manage interfaces, dependencies, and operational posture during construction.
Readiness Preparation
Build operating capability: procedures, staffing, training and familiarization, maintenance and supply-chain readiness.
Testing, Trials & Assurance
Integrate and test systems, run operational trials, resolve issues, and assemble assurance evidence.
Activation
Execute the activation event — opening, startup, energization, go-live, or RFS — under a go/no-go decision.
Transition
Transfer responsibility and operating state from the delivery or temporary org to the permanent operating organization.
Handover & Acceptance
Accept the handover package, load asset data into EAM/CMMS, and disposition open items.
Stabilization
Run hypercare and early-life operations (D+30 / D+60 / D+90), monitor performance, and close residual issues.
Operations & Benefits Realization
Sustain operations and track realized benefits against the business-case commitments.
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.
The same concept, in each industry's own words.
The shape of the lifecycle is shared across markets. The gates, evidence, and authority are each industry's own — so the model carries the concept, and each sector keeps its native vocabulary.
What Owner Scope Management is — and is not.
OSM is regularly mistaken for an adjacent discipline it actually sits above. Each of these is real and necessary; none of them governs the owner's readiness layer.
Bigger than one industry
ORAT is aviation's expression of owner readiness. OSM is the cross-industry model ORAT is one instance of — the same discipline in energy, transit, healthcare, and data centers.
Beyond "the system works"
Commissioning proves the system functions — a delivery outcome. OSM proves the owner can operate it: criteria met, evidence accepted, gates cleared, operations ready.
Above schedule & cost
A PMIS governs delivery — schedule, cost, and scope. OSM governs readiness, evidence, and acceptance, and references the PMIS rather than replacing it.
The owner's accountability
Project management delivers the scope. OSM governs the owner's go-live accountability — the work that can't be handed to a delivery contractor.
Governed, not stored
A repository stores files. OSM governs which evidence is accepted, current, and tied to a specific criterion and gate — the difference between having a document and proving readiness.
Decisions, not just views
BI reports status. OSM produces defensible go/no-go decisions from accepted evidence — and publishes to BI rather than being replaced by it.
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.
The Checkpoint 0 diagnostic places your program on this model and identifies the data prerequisites for AI-ready operations.
How to read this page. Owner Scope Management, Ready Score, Checkpoint 0, and Opti are Citiri terms and category framing — not established industry standards. The lifecycle shown is Citiri's canonical eleven-stage owner-scope model (L0–L10). In "one model, many languages," the Citiri concept is our canonical term and each industry-standard entry is that sector's own established vocabulary, aligned to — not equated with — the Citiri concept; authority and timing genuinely differ (for example, a regulatory hard gate such as a PSSR or an AHJ approval is not the same as an owner-led readiness review).
