 A Frameworks-Free Look at Enterprise Architecture
by Svyatoslav Kotusev, Mohini Singh and Ian Storey

The concept of Enterprise Architecture (EA) is typically associated with popular EA frameworks.  However, EA frameworks are far from the practical realities and typically adapted or simplified to fit the needs of specific organizations.  Even if used as information sources, they hardly explain the real essence of an EA practice.  The frameworks-free conceptualization of EA as a set of Principles, Visions, Standards, and Models presented in this article provides a clearer, more meaningful, realistic, and actionable explanation of the notion of EA.  Additionally, this article provides actionable “one minute” guidelines for mastering these four essential components of EA.

Why is Family Medicine Different?
by Matthew Mihelic, MD and Gregory H. Blake, MD

An understanding of the role and function of Family Medicine in the healthcare system can provide important insights for Enterprise Architecture.  It is often stated that the thought process utilized by Family Medicine physicians is different from that of specialty physicians, but heretofore there has been little or no analysis of what that difference is.  This article examines that difference from the perspective of the complex adaptive system that is healthcare today, and shows how it is that Family Medicine physicians perform the vital function of decreasing the entropy or disorder in the patient care system via decision loops, as opposed to the decision trees of linear or classical logic.  The generalist function of Family Medicine physicians results in the integration and coordination of the various specialty functions in healthcare.

How Easy is it to Standardize a Practice?
by Harry Hendrickx

This article discusses the process to get from insights to a standardized practice. It is a personal view and professional perspective on how that process has evolved. It is personal in the sense that the author describes his own view on the evolution of a practice over more than 25 years, and professional because the author has been involved in initiatives to enhance and develop the profession. He has followed in parallel a practitioner’s as well as academic path. It is argued that development of an open standard is non-linear but that it can also be governed when the critical aspects of the process are well understood. The author has summarized the lessons learned and concluded with the following critical aspects: a common problem statement; trust and open mindedness to overcome differing personal, communal, or organizational interests; power as well as a social process to handle political situations; authority and credibility on the content – from academia as well as thought leaders – to set the process in motion; and a formalized process to reinforce progress and openness. The article describes when and how these aspects have made a difference during the process. He also concludes that the social process as well as academic peer reviews are equally important.

Case Study: How to use Enterprise Architecture to Secure a Coherent Architecture for Clinical Logistics, Service Logistics, and Scheduling in a New Hospital Construction Project
by Jonas Hedegaard Knudsen

The Danish government decided in 2008 to spend 10 billion Euros on 16 new hospital construction projects. In Odense, the budget is 1.3 billion Euros in total and will be approximately 220.000 m
2. The hospital will be ready in 2022. The TOGAF® framework has been used in order to secure a coherent and semi-automated logistics system, where clinical logistics, service logistics, and planning/scheduling (the Logistics Complex) are the central elements. The project has identified those three areas as interdependent and most important, leaving out systems like Electronic Health Records (EHR). It has been crucial for the project that clinicians do not interact with the service logistics system, but instead focus on their clinical workflow through interaction only with the clinical systems at the hospital. A Real-Time Location System (RTLS) has been acquired, so it is possible to track mobile equipment, beds, trolleys, patients, and personnel. Based on the exact position of equipment or personnel/patients, tasks can be created or registration made automatically in the surrounding application. The new logistics solution will help the hospital cope with fewer beds, be more efficient, and increase quality overall. The TOGAF framework has proven itself as a reliable framework in order to map the business architecture of the future and select and design appropriate information system architecture and technology architecture. The purpose of this article is propose a reference architecture for the technology and tools portion of our profession.

Wanted – A Reference Architecture for Enterprise Architecture Repositories
by Joe Maissel

The discipline of Enterprise Architecture (EA) has a number of well established frameworks that help define the work we do. As such, they are largely focused on the people, process, and outputs of EA. But what about the technology that enables our work? What about “IT4EA”? It is my contention that this work has largely been neglected by the EA community and left to vendors to solve. As a result, the market for EA tools is fragmented and difficult to understand or evaluate. The purpose of this article is propose a reference architecture for the technology and tools portion of our profession. 

About the Journal of Enterprise Architecture:  The Journal of Enterprise Architecture (JEA) is an Association of Enterprise Architects® (AEA) member benefit.  It is published four times per year by the AEA.

The JEA provides the AEA global community with professional development material that can both improve members’ understanding of the discipline of enterprise architecture (EA) and their ability to successfully practice EA.  The JEA publishes material concerning the application of architectural thinking to the design, implementation and operation of any form of human enterprise, with special attention to the use of information systems in the context of commercial business, non-profit, governmental and similar enterprises.
