Last updated March 23, 2019

Danny Greefhorst (born 31 December 1972) is a Dutch enterprise architect and consultant at ArchiXL, known for his work in the field of enterprise architecture.^[1]^[2]

Enterprise architecture (EA) is "a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes."

Biography

Greefhorst obtained his master in computer science at Utrecht University in 1995 with the master thesis ""A Simulation Environment for Ariadne."^[3] Furthermore, he became IBM Certified Senior IT Architect in 2004. He is TOGAF 9 level 2 and ArchiMate 2.0 certified.^[4]

Utrecht University is a university in Utrecht, the Netherlands. Established 26 March 1636, it is one of the oldest universities in the Netherlands. In 2016, it had an enrolment of 29,425 students, and employed 5,568 faculty and staff. In 2011, 485 PhD degrees were awarded and 7,773 scientific articles were published. The 2013 budget of the university was €765 million.

After graduation Greefhorst started his career at the Software Engineering Research Centre in Utrecht in 1995. He worked in various roles from software researcher, designer, architect, developer, tester and webmaster to class instructor, coach, seminar organiser, and IT consultant, and published his first papers. In 2001 he moved to IBM, where he became Senior IT Architect for five years. After another year as Principal Consultant at the management consultancy firm Yellowtail, he started his own enterprise architecture consultancy firm named ArchiXL.^[4]

International Business Machines Corporation (IBM) is an American multinational information technology company headquartered in Armonk, New York, with operations in over 170 countries. The company began in 1911, founded in Endicott, New York, as the Computing-Tabulating-Recording Company (CTR) and was renamed "International Business Machines" in 1924.

Since 2010 Greefhorst chairs the governing board of Via Nova Architectura, and since 2014 also chairs the governing board of the Special Interest Group on architecture of the Dutch Computer Society Ngi-NGN.^[4] In 2011 he received a medal of honor from the Dutch Architecture Forum for his contributions to the Dutch enterprise architecture community.^[5]

Work

Architecture Principles, 2011

In "Architecture Principles – The Cornerstones of Enterprise Architecture," (2011) Greefhorst and Proper present an extensive study of architecture principles.^[6] They presume that "enterprises, from small to large, evolve continuously. As a result, their structures are transformed and extended continuously. Without some means of control, such changes are bound to lead to an overly complex, uncoordinated and heterogeneous environment that is hard to manage and hard to adapt to future changes. Enterprise architecture principles provide a means to direct transformations of enterprises. As a consequence, architecture principles should be seen as the cornerstones of any architecture."^[7]

Henderik Alex (Erik) Proper is a Dutch computer scientist, Professor of Information Systems at the Radboud University Nijmegen, and IT consultant, known for work on conceptual modelling of information systems and enterprise engineering.

Furthermore, they argue, that this work "provide[s] both a theoretical and a practical perspective on architecture principles. The theoretical perspective involves a brief survey of the general concept of principle as well as an analysis of different flavors of principles. Architecture principles are regarded as a specific class of normative principles that direct the design of an enterprise, from the definition of its business to its supporting IT. The practical perspective on architecture principles is concerned with an approach to the formulation of architecture principles, as well as their actual use in organizations."^[7]
