Enterprise Architecture

Enterprise Architecture

It is more than 30 years ago since  John Zachman in 1982 first mentioned Enterprise Architecture in the public domain. Since then, various different enterprise architecture frameworks (EA frameworks) have been developed. At present, there is a tremendous proliferation of architecture frameworks; hundreds are in current or recent use, and new ones are being created. Architects, architecting organizations and enterprises need ways to understand, choose and adapt architecture frameworks for their use.

Together with the Global University Alliance (GUA) the standards organizations ISO, IEEE, CSIR and OMG intend to solicit information and research into basis for the comparison, assessment, and selection of architecture frameworks and their evolution as architecting as a practice matures.

Research Focus

Information and research is sought on topics related to the understanding and comparison of Enterprise Architecture Frameworks (EAFs), including, but not limited to:

    • Semantic foundations of EAFs
      • What common Ontology aspects do they have?
      • What common meta objects do they have?
    • Organization and modularization principles of EAFs
    • Extension and customization mechanisms for EAFs
    • Comparing EAFs, method and approaches for comparison
    • What Enterprise Architecture roles exist
    • Concern-oriented considerations:
      • What concerns are well-supported (typical concerns they work with)?
      • What concerns are not currently handled?
    • Model and viewpoint considerations:
      • Typical models they work with?
      • What challenges are not being addressed by current models?
    • What are their tasks? How are EAFs situated with respect to other life cycle processes and activities?
    • Which Enterprise Architecture measures (KPIs) exist
    • Tool support: what impediments, opportunities exist?
    • The most common Value of Enterprise Architecture

Findings

Already in 2004, our analysis identified a pattern. Our analysis and research across 56 different industries revealed that there is an arranged way of thinking, way of working and way of structuring concepts and the work done within Enterprise Architecture. Figure 1 is an overview of the most common identified way of thinking, ways of working and ways of structuring concepts. We also identified that there is a connection between the arranged way of thinking, way of working, way of structuring and how enterprise architecture would work better in enterprise layers and their sublayers (figure 2). Our research and analysis results has then lead to a development of whole new concepts that was based on a common way of thinking, working and structuring within the layers and their sublayers (see figure 3).

Baseline For Research

As a basis for the research we will base it on the international standard uniformity and interoperability, we adopt the conceptual model established in ISO/IEC/IEEE 42010:2011, Systems and software engineering — Architecture description, as a foundation for exploring architecture frameworks, defined as follows:

Architecture Framework: conventions, principles and practices for the description of architectures established within a specific domain of application and/or community of stakeholders.

Following the ISO/IEC/IEEE Standard, an architecture framework should be specified by:[1]

    • information identifying the framework;
    • one or more concerns;
    • one or more stakeholders having those concerns;
    • one or more architecture viewpoints (and their specifications);
    • correspondence rules, integrating the viewpoints;
    • conditions on applicability;
    • relationship with the provisions of the ISO/IEC/IEEE 42010 conceptual model (“meta model”).
