TOGAF vs. BIAN? The question makes little sense. TOGAF is a modular framework for enterprise architecture. BIAN is an industry reference model that replaces most of the TOGAF Content Framework for high performing financial organizations.

How would they conflict?

TOGAF vs BIAN - Content Framework

The TOGAF Standard is modular, scalable, and configurable. By design, the TOGAF framework is not prescriptive. The TOGAF framework provides the universal essential scaffolding for the three central problems facing enterprise architects:

  1. How to describe an enterprise architecture
  2. What is needed to have an enterprise architecture capability
  3. How to develop an enterprise architecture

The BIAN Service Landscape is a blueprint for the logical components of a bank’s IT environment. A logical blueprint for a bank's IT environment. Sounds like an industry specific reference architecture.

Integrating the TOGAF Standard with the BIAN Service Landscape is available from The Open Group publications library and BIAN.

TOGAF Architecture Continuum TOGAF's architecture continuum explains how to integrate the BIAN Service Landscape into your architecture.

BIAN provides an industry specific IT architecture. If you work in financial services and you are not using BIAN, you are choosing to slowdown your delivery of useful enterprise architecture.

TOGAF vs BIAN play to the strengths

BIAN Banking Industry Architecture Reference Model Both the TOGAF standard and BIAN are exhaustive in their domains.

The joint Open Group / BIAN paper, Integrating the TOGAF Standard with the BIAN Service Landscape, brings these two frameworks together and shows banking industry architects the opportunity they have to reap the synergies of both frameworks and speed up their work.

The key constituents of the BIAN Service Landscape are:

  • Business Area: A Business Area groups together a broad set of business capabilities. They define them to be aspects of business activity that have similar supporting application and information-specific needs (e.g., “Operations & Execution”, “Reference Data”, “Sales & Service”).
  • Business Domain: Defines a coherent collection of capabilities within a Business Area. They associate Business Domains with skills and knowledge recognizable in the banking business (e.g., “Payments” as a Business Domain within the Business Area “Operations & Execution”).
  • BIAN Service Domain: The finest level of partitioning. Defining unique and discrete business capabilities. The BIAN Service Domains are the “elemental building blocks” of a service landscape (e.g., “Payments Execution” is a BIAN Service Domain within the “Payments” Business Domain).
  • Service Group: A set of Service Operations, is owned by a BIAN Service Domain. It is an interface to the BIAN Service Domain. We define it in terms of business semantics rather than in technical IT terms (e.g., “manage payment order”).
  • Service Operation: Represents a service defined at the level of business semantics, specifying the access to one or more capabilities of a BIAN Service Domain (e.g., “execute payment order” or “update payment order” are Service Operations of the Service Group “manage payment order”).


BIAN is the Banking Industry Architecture Network. The BIAN Service Landscape is a blueprint for the logical components of a bank’s IT environment. Leveraging this blueprint and the Service Domain Specifications will significantly speed up architecture initiatives—be it in the planning of change initiatives, in the procurement of components, or the benchmarking of an existing landscape against best practices.

TOGAF vs BIAN & Navigate

We have not aligned BIAN to Conexiam Navigate.

When we integrate it, we will following the guidance in the Leader's Guide, replace rather than re-imagine. If you are in Financial Services, adopt the BIAN Service Landscape concepts and abandon generic concepts like the TOGAF Content Metamodel.

The Leader's Guide speaks to integrating an industry specific reference architecture into your EA Repository.
