BITA*: Business-IT alignment framework of multiple collaborating organisations

Abstract

Context Businesses today must collaborate in a coordinated fashion. To collaborate, they must align their business processes and IT by complying to a common reference architecture. The common reference architecture that addresses their specific collaboration requirements is generally an adaptation of an existing generic reference architecture. However, a design framework for adapting reference architectures is lacking. Objective In this paper we propose a design framework for aligning business processes and IT across diverse collaborating organisations in order to derive a more specific reference architecture from a generic one. Method We developed the design framework using the guidelines of ISO/IEC/IEEE standard for modelling design viewpoints and validated it in a real-life business case study. Results We developed an architectural design framework which we call BITA* that is composed of three coherent architectural design viewpoints. The BP2BP alignment viewpoint provides alignment modelling abstractions for business analysts to be used to align business collaboration processes. The IT2IT alignment viewpoint provides alignment modelling abstractions for software architects to be used to align distributed IT systems. The BP2IT alignment viewpoint provides alignment modelling abstractions for interdisciplinary teams of business and IT specialists for aligning the mapping of business collaboration processes and the underlying distributed IT. The modelling abstractions are applied in a case study to derive a reference architecture for meat supply chain transparency systems. Conclusion A key challenge in developing the design framework is the difficulty of comparing models of business processes and IT that come from diverse organisations. Our main contribution is the set of modelling abstractions, which enabled us to represent business processes and IT in a uniform and comparable manner, and the systematic approach for applying the modelling abstractions. The framework is applied in the agri-food sector and needs to be evaluated further in multiple case studies from various application domains.
