Introduction
The Organizational Architecture Standard (OAS) is an open international standard for designing, governing, and executing organizations as computational systems.
What is OAS?
OAS provides a common architectural language that can be understood by:
- Human architects — domain experts who design organizational structures
- AI agents — autonomous systems that operate within organizational boundaries
- Software platforms — runtime environments that execute organizational models
Why OAS?
Traditional approaches to organizational design suffer from several fundamental problems:
- Ambiguity — Organizational charts and process documents are interpreted differently by different stakeholders
- Stagnation — Static documents become outdated the moment they are published
- Opacity — It is impossible to automatically verify whether an organization is operating according to its design
- Fragmentation — Different tools, formats, and methodologies create silos
OAS solves these problems by treating organizations as executable systems with formally defined semantics.
Core Concepts
Organization as a System
In OAS, an organization is not a collection of people and roles. It is a system with:
- State — the current configuration of the organization
- Behavior — defined by state machines and event handlers
- Interfaces — contracts between organizational units
- Invariants — constraints that must always hold
The OAS Ontology
At the heart of OAS is a formal ontology that defines:
- Entities — the fundamental objects (organizations, agents, processes, policies)
- Relations — how entities connect (reports-to, depends-on, delegates-to)
- Types — classification hierarchies with inheritance
- Constraints — rules that must be satisfied

Architecture Overview
OAS is organized into seven specification layers:
| Layer | ID | Status | Description | |-------|-----|--------|-------------| | Foundation | OAS-FND | Stable | Core ontology and primitives | | Semantic | OAS-SEM | Stable | Type relations and constraints | | Governance | OAS-GOV | Draft | Policy framework and compliance | | Runtime | OAS-RUN | Draft | Execution semantics | | Platform | OAS-PLT | Experimental | API and SDK | | Reference | OAS-REF | Stable | Reference implementation | | Certification | OAS-CER | Draft | Conformance criteria |
