Business Building Blocks as Coordination Mechanism for Enterprise Transformations
Enterprise architecture management (EAM) aims at aligning business and IT. Therefore, EAM analyzes the current and defines the target state. In order to reach the target state, EAM plans and monitors transformations affecting business processes, information systems and the underlying IT infrastructure. Thereby, domains are a widely used tool in order to reduce the complexity. The domains structure the enterprise architecture, e.g. according to the business fields a company is working in. Resources and responsibilities are assigned to these domains and transformations are then coordinated within domains. This approach, however, poses the risk that business requirements are solved redundantly although an existing IT system from another domain could have been reused. It even hinders an integration of the IT systems used in the different business fields. This paper describes an approach for coordinating transformations based on so-called business building blocks (BBBs). BBBs define the essential business elements independent from their implementation, with a granularity suitable for reuse within and across domains. Our approach determines who is responsible for providing a solution to a certain business requirement by assigning clear responsibilities to the corresponding BBB. This business outcome-driven approach helps focusing on business requirement solutions instead of managing system solutions. Ideally, there is exactly one responsible authority per BBB. In the paper, we provide a description of our BBB identification method and relate the suggested approach into one of the currently most widely adopted EA frameworks, i.e. The Open Group Architecture Framework (TOGAF). We report about the experiences we made when using this method in various EAM projects and recommend best practices.
