- ZeitschriftenartikelBusiness Process Decomposition - An Approach Based on the Principle of Separation of Concerns(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 5, Nr. 1, 2010) Caetano, Artur; Silva, António Rito; Tribolet, JoséThe functional decomposition of a business process breaks it down into progressively less granular activities. Decomposition contributes to the modular design of a system, the reuse of its parts and to its overall comprehensibility. But achieving these qualities requires a business process to be decomposed consistently, which implies it is always split into an identical set of activities according to a specific purpose, regardless of the modeller’s and modelling context. This paper describes an application of the principle of role-based separation of concerns to consistently decompose a business process into its constituent atomic activities, thus separating its distinct features and minimising behaviour overlap. An activity is abstracted as a collaboration between role types that are played by entities. The decomposition method successively separates the overlapping roles until an activity is specified as a collaboration of an orthogonal set of role types. The method facilitates the consistent decomposition of a business process and the identification of its atomic activities. The relevance of the method is assessed through a number of scenarios according to the guidelines of design science research.
- ZeitschriftenartikelThe Role of Enterprise Governance and Cartography in Enterprise Engineering(Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 9, Nr. 1, 2014) Tribolet, José; Sousa, Pedro; Caetano, ArturEnterprise artography is fundamental to govern the transformation processes of an organisation. The artefacts of enterprise cartography represent the structure and dynamics of an organisation from three temporal views: as-was (past), as- is (present), and to-be (future). These views are dynamically generated from a continuous process that collects operational data from an organisation. This paper defines a set of enterprise cartography principles and provides an account of its role in understanding the dynamics of an organisation. The principles are grounded on control theory and are defined as a realisation of the observer and modeller components of the feedback control loop found on dynamic systems. As a result, an organisation can be abstracted as a dynamic system where a network of actors collaborate and produce results that can be depicted using cartographic maps.
