Enterprise Architecture Modeling with the Unified Modeling Language

Abstract: This chapter describes the key concepts for modeling the organization’s enterprise architecture using the Unified Modeling Language (UML). Enterprise architecture consists on defining and understanding the different elements that shape the organization and how these elements are inter-related with the purpose of understand and facilitate organizational evolution and change. It separates core organizational concerns as different architectural views; the authors argue that modeling the multidimensional aspects of the enterprise should be organized into five architectural components: Organization, Business, Information, Application and Technological architectures. These five components are supported in a small set of fundamental concepts described using UML 2.0. Furthermore the authors argue that any organization model may be abstracted to three elements: Activity, Role and Entity. The authors also propose a set of rules for assessing the alignment between the enterprise architectural elements.

Adding a Human Perspective to Enterprise Architectures

Abstract: Enterprise modeling, commonly supported by enterprise architecture frameworks, has proved to be an effective communication tool that facilitates the development of applications aligned with the business. These modeling frameworks are concerned with organization's design rather than its actual implementation. We argue that modeling the actual implementation of organizations can be a valuable communication tool not only for systems development but also for organizational analysts, managers and workers. However, this kind of usage requires the inclusion of a human perspective in current enterprise architectures. In this paper, we propose to extend the CEO enterprise architecture with a human view based on a conceptual model consistent with contemporary paradigms of organizational science. The proposal is illustrated with examples drawn from a case study.

Representing organizational competencies

Abstract: Business activities within the organization are performed by a number of human or automated actors. For the organization to adapt to internal or external changes it must be able to understand how and why actors are related to and assigned to processes. This requires a consistent representation of the services required by the organization's processes and those provided by its actors. This paper focuses on defining the concepts that allow structurally aligning human actors and business processes through the description of the organizational competencies required to perform processes' activities. These structures can then be used dynamically within a marketplace-based model, supporting the management of actors and activities according to the supply and demand of competencies.

Integrating engineering, cognitive and social approaches for a comprehensive modeling of organizational agents and their contexts

Abstract: Organizational models produced within computer science fields have proved to be effective communication tools in developing shared understandings of the design of organizations and systems. We argue that these models can also be valuable in capturing the actual implementation of organizations. However, this kind of usage requires the development of enterprise representations that (1) acknowledge the complexity of organizations and its agents and (2) are able of capturing the situated and dynamic behavior of organizational agents. This paper describes how engineering, cognitive and social approaches to context are integrated in a conceptual framework to model organizational agents and their contexts of interaction to address these issues. This integration is illustrated with examples from a case study.

Organizational Functions And Enterprise Self-Maintenance: A Framework For Integrating Modelling, Monitoring and Learning

Abstract: Process orientation is a major concern nowadays. For this reason there have been great advances in business process modelling as a means to better understand and facilitate organizational operation and evolution. However, organizational functions like logistics, quality, finance, etc. still exist and strongly influence aspects like change processes, or the structuring of organizational units even if a “process culture” is established. This paper proposes a framework for integrating modelling, monitoring and learning aspects associated with the functional dimension of the enterprise. This framework is based on: (1) an ontology proposed (in another forthcoming paper) for the functional dimension of an organization; (2) the fundamental concepts: entity, role and activity, that are the base for current research work by other authors, on modelling other dimensions or concerns of an enterprise architecture. Also an example of application of the framework is presented as a proof of concept.
