Viable
The part can perform its minimum function under current conditions. Diagnostic question: can it operate now without immediate failure or external rescue?
From viable to regenerative.
A four-tier maturity model for ocean organisations.
Maturity is assessed per operating-system part, not assigned as one flattering label to an entire organisation. Progress requires evidence, and regeneration is treated as a destination rather than an unsupported claim.

Named mechanism
Measure maturity without hiding weak interfaces.
The Ocean Organisation Maturity Model helps institutions assess how each part of their operating system currently performs and what a credible next level requires.
An organisation can be resilient in finance but only viable in governance, or sustainable in operations while its partnership model remains fragile. The model preserves that variation rather than averaging it away.
Each tier is tested through evidence and a diagnostic question. Regeneration is the destination and highest tier; it is never claimed without measurable improvement in the systems on which the organisation depends.
Canonical definition
Maturity is assessed separately across the eight parts of the Ocean Operating-System so that strengths, dependencies and delivery risks remain visible.
The four maturity tiers
4 evidence-led tiersSustainable
The part can continue without consuming the capital, capability, trust or ecology it depends on. Diagnostic question: can it maintain performance without degrading its foundations?
Resilient
The part can absorb shocks, adapt and retain its purpose and accountability. Diagnostic question: can it change under pressure without transferring the cost elsewhere?
Regenerative
The part measurably improves the ecological and institutional systems it relies on. Diagnostic question: what evidence shows that the system is stronger because this organisation operates within it?
The model is a decision aid, not a badge. Its value lies in making the next constraint visible and connecting improvement priorities to the wider operating system.
