The basics

The Banking Industry Architecture Network (BIAN) is an association of banks, solution providers and educational institutions with the shared aim of defining a semantic service operation standard for the banking industry.


BIAN’s expectation is that a standard definition of the business functions and service interactions that describe the general internal workings of any bank or organization in the banking ecosystem, will be a significant benefit to the industry. When compared to a proliferation of proprietary designs, such an industry standard provides the following main benefits:

•   it enables the more efficient and effective development and integration of software solutions for the Banking Industry

•   it improves the operational efficiency within the Industry and provides the opportunity for greater solution and capability re-use within and among organizations in the Banking Industry

•   it supports the current need for more industry integration and collaboration by the usage of (open) APIs

•   it supports the adoption of more flexible business service sourcing models and enhances the evolution and adoption of shared third party business services.

Relating BIAN to the phases of the TOGAF ADM For each TOGAF ADM phase, only those BIAN deliverables are included that are a direct input for that ADM phase. Since the impact of those BIAN deliverables is fully integrated in the output of that ADM phase, the influence on later ADM phases is fully covered, see figure. Applying the TOGAF ADM produces and enriches the BIAN Service Landscape and BIAN Business Scenarios specific to the organization. Furthermore, the results

can be fed back to the BIAN community to extend and enrich the BIAN deliverables.


Target audience

Enterprise Architects, business architects, IT architects, application architects, data architects,  system  architects, solutions architects, process architects, domain architects, senior managers, project leaders and anyone committed to work within the reference framework designed by an Enterprise Architecture.

Scope and constraints

The role of the BIAN Service Landscape is to provide a common language for the definition of a banking ecosystem. This language is canonical and implementation- and technology agnostic, so it could be applied in a wide range of organizations and technology environments.

By combining the different layers of the overall BIAN Architecture, it provides financial institutions all around the globe a unique starting point for business and IT renewal in a highly controlled and consistent manner.

Today BIAN is primarily focusing on the Banking industry. But other financial services, like Insurance and Pensions can already benefit from it. It is expected that BIAN will deliver models for these industries in the upcoming years.
