Case Study: Archi Banking Group

The Archi Banking Group Case Study is a fictitious example developed to illustrate the use of the BIAN Reference Model, ArchiMate modeling notation, and the TOGAF^® framework.

The BIAN Reference Model is meant to be used as a reference to develop a bank-specific Enterprise Architecture.

An example use of the BIAN Reference Model, expressed in the ArchiMate language while applying the TOGAF framework, is described in the Case Study: Archi Banking Group (see Referenced Documents). This is a fictitious example inspired by a real-life use-case; i.e., the governance of a corporate program portfolio for payment change initiatives.

The Case Study describes a banking group composed of banks and legal entities in different countries. Each of the legal entity banks are working according to a group strategy, although each of the banks has their own identity and, as such, their own strategy. The dynamics of portfolio management are described using the federated architecture approach. The Case Study covers all the architecture layers from strategic goals and strategy, the architecture landscape definition, opportunities and solution, migration planning, and implementation governance, and the need to adapt the banking architecture via architecture change management, in a segmented architecture Enterprise Architecture organization. It demonstrates how the ArchiMate Specification, the TOGAF framework, and BIAN can be used to create high-quality architectures. It can also be used as an inspiration to apply the combination of the three standards in real-life banking.
