Summary comparison – Orthogramic Metamodel and BIZBOK

The Orthogramic Metamodel and BIZBOK both aim to provide structured, repeatable approaches to business architecture. However, they differ significantly in scope, usability, and implementation philosophy.

Scope and domain coverage

BIZBOK focuses on a core set of business architecture domains including capabilities, value streams, strategies, stakeholders, and information. The Orthogramic Metamodel retains these but significantly extends the model to include a wider set of domains such as:

• Policy, Initiatives, Performance, Technology, Channel, People, Customer, Market, Finance, Risk Management, Supply Chain, Innovation, and Sustainability

This broader coverage reflects the interconnected realities of large organisations and enables modelling of operational, strategic, regulatory, and environmental dimensions within a single framework.

Cross-domain referencing

Where BIZBOK suggests relationships between domains at a conceptual level, the Orthogramic Metamodel defines these explicitly through schema-based cross-domain relationship mappings. For example, customer segments can be directly linked to capabilities, value streams, and products, with structured metadata capturing the nature and strength of those relationships. This makes traceability, impact analysis, and strategic alignment programmatically actionable rather than interpretive.

Schema-first and automation-ready

The Orthogramic Metamodel is schema-first by design. Each domain is defined using public JSON Schemas, enabling validation, automation, and integration with digital platforms. This allows business architecture to move beyond visual mapping and into dynamic, governed, and interactive environments—supporting real-time data, structured recommendations, and stakeholder-specific insights.

Strategic responsiveness

The Orthogramic Metamodel includes a dedicated Strategic Response Model, which links triggers and rationales to formal organisational responses, initiatives, and performance indicators. This is not a feature in BIZBOK and reflects Orthogramic’s emphasis on continuous alignment and responsiveness to internal and external change.

In summary, while BIZBOK provides a foundational business architecture framework, the Orthogramic Metamodel extends and operationalises it to meet the demands of modern strategy execution. The additional domains and schema-based cross-domain relationships allow it to support real-time insight, system integration, and federated participation across the enterprise.
