A role-based enterprise architecture framework

Abstract: Organizations deal with contrasting domains such as people, strategy, business processes, and information systems as well as with their representation, alignment and governance In this setting, different approaches to enterprise architecture have been introduced to address these concerns This paper focuses on describing an enterprise architecture framework centered in three core concepts (role, entity and activity) from which domain-specific concepts are derived from The framework abstracts the organization's domains as five architectural views (organization, business, information, application and technology) and captures the concept dependencies and relationships across the different domains

Enhancing Organizational Self Awareness - The As-is Enterprise Model Dynamic Updating Process.

Abstract: The aim of the work described in this paper is to set up the as-is enterprise model continuous updating process and to develop a supporting tool. The as-is enterprise model continuous updating process uses the annotations as a mechanism to put the business actors “talking” with the representation of their activities, either in action and interaction contexts, extracting knowledge and turning it explicit in the as-is enterprise model . The business actors can act as active updaters of the as-is model through the comparison between the modelled activities and the ongoing real executed activities. In this way, the enterprise model, which represents several aspects and perspectives of organizations, can help building and maintaining organizational self-awareness by adding knowledge to several organizational levels (individual, group, process/functions). The process and the supporting tool are running in a governmental organization and the results revealed that they could have an important role, not only in gathering the information needed to update the model, but also allowing the opening communications channels to share and acquire additional organizational knowledge.

A bottom-up approach for the representation and continuous update of technology architectures

Abstract: In organizations where there are not any concerns about guiding Information Systems’ (IS) development using Information Systems Architecture (ISA) models updated in a strict and automatic fashion, business requirements and external pressures frequently lead to an increasing gap between current Information Systems and the latest version of their ISA and, in particular, their Technology Architecture (TA) models, when they exist. One of the causes for the lack of "investment" in TA models is the considerable effort required to "discover" infrastructural features that serve as input to the development of such Architectures. Such a task can only be achieved using automatic approaches. This work is focused on devising a bottom-up approach for the representation and continuous update of TAs in organizations using a tool that automates the discovery of architectural evidences (through network events) and mappings between those architectural evidences to a modeling language, using logical deduction rules. This approach also features a process based on the annotation mechanism to enable interaction contexts that allow actors in an organization to make explicit their knowledge about their perception of the TA reality. This approach was applied in a concrete case study, but it can be applied to any organization in any context.
