Presenting a Theory-Based Model for IT Management Responsibilities

Enterprise architecture is all about the IT systems, the IT organization, and how they provide value to the business. Nonetheless, the complex relations within this trinity have previously been overlooked in literature. The herein proposed reference model for IT management responsibilities therefore aims at explaining how IT organizations and IT systems serve as value enablers to the business, thus clarifying the boundaries of IT management’s responsibilities. The model is based on extensive literature studies and has been tested in a series of empirical studies.

Enterprise Architecture and Change Management

This article provides an analysis of how enterprise architecture (EA) promotes change and provides a framework for change management. he article first explores the reasons for organizations to change and points out elements such as technological trends and market pressures as determinant forces that foster these changes. As a preamble to the analysis of EA as a framework for change management, an introduction to the concept of change management is made by presenting several perspectives. The article concludes by recognizing EA as a force that encourages change, and the contributions that EA makes to reducing stakeholders resistance to change.

The Future of Information Technology – Part 4: Self-Adapting System Architecture 2018-2026

Though it is largely an abstract concept, enterprise architecture (EA) has shaped, is shaping, and will continue to shape information technology. This four-part article traces the author’s observations and predictions about the current and future state of information technology, and the role that EA will play in that evolution. Part 4 looks ver far forward to the next architectural step beyond MEDA that may be called the Self Adapting System Architecture (SASA). Given that SASA is 15 to 20 years out, it is more of an IT architectural vision than a true architecture like SOA or MEDA. Yet, the technology on which it is based has been in university computer science laboratories for 10 to 20 years. This technology has been used in many visionary IT experiments, but has not moved from basic research to research and development yet, in part because it is multifaceted intricate, convoluted, and complex. More importantly, the migration to SASA will require significant changes in business processes and organizational culture.

The Methodology for Business Transformation v1.5: A Practical Approach to Segment Architecture

This article describes the Methodology for Business Transformation v1.5 and how it can be used as a step-by-step approach for developing architecture. The recent publication of OMB’s Federal Enterprise Architecture (FEA) Practice Guidance clearly articulates the inter-relationships between the three architecture levels: enterprise, segment, and solution. This article introduces the MBT v1.5 as a practical approach to developing these architecture levels with executive and mission area leadership, participation, and buy-in. This article is written to encourage federal and private sector architecture practitioners to use the MBT in their own organizations. The MBT is feely available as an open-source methodology . It is available at www.doi.gov/ocio/architecture/mbt.

Trends in Governmental Enterprise Architecture: Reviewing National EA Programs – Part 1

This article is the first in a series of three, where we will analyze and evaluate governmental enterprise architecture policies and practices from an international perspective. This first article presents the overall findings from an international study, we have made about governmental EA, and introduces an evaluation and assessment methodology. In the forthcoming articles, we will present an evaluation of selected government’s EA maturity in a comparative perspective, and discuss the usage of maturity models in policy assessment. The third article will present the findings from a 2007 international benchmarking study of more than 20 governments around the world.
