Overview
ISO/IEC 16680:2012 - The Open Group Service Integration Maturity Model (OSIMM) defines a standardized model and assessment process for measuring an organization’s service integration and SOA (Service-Oriented Architecture) maturity. Published as an international standard from The Open Group, OSIMM v2 provides a quantitative framework to assess current and desired maturity, identify gaps, and create a prioritized roadmap for incremental adoption of service-based approaches.
Key Topics and Technical Scope
- Seven maturity levels that characterize progressive capabilities:
- Level 1: Silo
- Level 2: Integrated
- Level 3: Componentized
- Level 4: Service
- Level 5: Composite Services
- Level 6: Virtualized Services
- Level 7: Dynamically Re-Configurable Services
- Seven dimensions used for assessment:
- Business; Organization & Governance; Method; Application; Architecture; Information; Infrastructure & Management.
- Assessment mechanics:
- Maturity indicators, assessment questions and mappings per dimension
- Service foundation levels and extensibility mechanisms to tailor the base OSIMM model
- A defined OSIMM assessment method with steps (identify pain-points and scope, extend model as needed, assess current state, define future state, identify gaps, and determine roadmap)
- Conformance and relationships:
- Guidance on extending the base model and references to relationships with other SOA standards and international technical committees (e.g., SC38, SC7).
Practical Applications and Users
- Who uses ISO/IEC 16680 / OSIMM
- Enterprise architects, SOA architects, CIOs, IT strategy consultants, program managers, and vendor-neutral governance teams.
- Practical uses
- Baseline current SOA/service integration maturity and benchmark progress
- Create business-aligned roadmaps for incremental service adoption that maximize benefits at each stage
- Prioritize investments in architecture, governance, information management and infrastructure
- Align organizational processes and governance to support service-based models and dynamic reconfiguration
- Benefits
- Objective, repeatable assessments that support decision-making, risk reduction, and phased modernization strategies.
Related Standards
- OSIMM aligns with The Open Group SOA work and references other SOA-related standards. The standard also documents its relationship to other international standards and technical committees (see sections on relationships to other SOA standards and ISO/IEC groups such as SC38 and SC7).
