Product-IT Inclusive Enterprise Architecture Management: An Approach Based on Ecosystems, Customer Journey and Data-Driven Business Opportunities

. Products have evolved from being solely composed of mechanical and electrical parts to complex systems that are connected to the Internet and form the basis for new kinds of functionalities and services. Such smart connected products include a substantial amount of software and information technology which can be called the “product-IT”. Enterprise architecture (EA) management is an established function in enterprises providing methods and tools for a systematic alignment of business and IT in an organization. However, EA models capture the details of business, information and technology architecture of an enterprise (i.e., the enterprise-IT) but usually do not include the product-IT. When value creation and delivery in an enterprise’s business model also includes the product-IT, a product-IT inclusive view on EA urgently is required. The focus of this article is the methodical support for integration of product-IT and enterprise-IT using enterprise architectures. The main contributions in this article are the conceptual expansion of EA management to become product-IT inclusive that is manifested in a proposal for an extended EA meta-model, and an approach and method components to handle product-IT inclusive EAM.
