Model Consistency as a Tool for Digital Business Architecture Verification

Digitalization of enterprises and introduction of digital products has become in recent years inevitable. In the global competition enterprises have to use all means available in order to be able to respond to competitors' innovations or even to be able to implement innovations which would take them ahead of the competition. With the rising complexity of the business and the information technologies used, there is inevitable that there have to be methods applied, which make possible for the digitalization projects to formulate the consistent and complete business requirements in form of business model (architecture) increasing so the chance that the following implementation will be successful. In this paper we describe the consistency rules and the necessary minimum of business architecture which should be modeled so that the business requirements can be clearly defined, and their completeness and correctness verified. The method is illustrated on the generally accepted EA standards TOGAF/ArchiMate, UML and BPMN and its benefits are discussed. We also provide the reader with a metamodel which specifies how these standards in the discussed topics match together. (C) 2019 The Authors. Published by Elsevier B.V.
