In "Architecture Principles – The Cornerstones of Enterprise Architecture," (2011) Greefhorst and Proper present an extensive study of architecture principles. 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."

In 2012 Proper was awarded the IFIP Outstanding Service Award from the International Federation for Information Processing (IFIP).

In the 2009 "Enterprise Architecture: Creating Value by Informed Governance," Op 't Land and Proper traced the notion of architecture in the field of information systems development. They summarized:

After graduation Proper started his academic as Computer Science researcher at the University of Queensland in Australia, and lecturer at the Queensland University of Technology. Back in The Netherlands in 1997 Proper started working in the software industry as consultant at Atos Origin in Amsterdam, and later for Ordina in Gouda. Back at the Radboud University Nijmegen he was appointed Associate Professor in 2001, and since 2002 Professor of Information Systems. From 2008 to 2010 he has been part-time consultant for Capgemini. Since 2010 he is also Professor and researcher at the Public Research Centre Henri Tudor in Luxembourg.

In his 1994 PhD thesis "A Theory for Conceptual Modelling of Evolving Application Domains," Proper developed a formal specification of information system development. This specification was based Object-role modeling, and was one of the many extensions to its basic framework. These extensions are basically abstract mechanisms, that "allow users to control the amount of detail seen at any given time."

Born in Rheden, Proper studied Computer Science at the Radboud University Nijmegen. In 1990 he received his MA, and in 1994 his PhD with distinction with a thesis entitled "A Theory for Conceptual Modelling of Evolving Application Domains" under supervision of Eckhard D. Falkenberg.

While Proper focussed on schema evolution with Object-role modeling, other researchers in the 1990s had focussed on a range of related topics. Halpin (2006) summarized that that research ranged from "reverse engineering, support for complex objects, process-event modeling, external schema generation... schema optimization, meta-modeling, subtype extensions, null handling, object-oriented mapping, unary nesting, [to] empirical research."

When software applications became larger and larger, people such as Shaw and Garlan coined the term software architecture. This notion of architecture deals with the key design principles underlying software artefacts. In the 1980s and 1990s, people became aware that the development of information technology (IT) should be done in conjunction with the development of the context in which it was used. This led to the identification of the so-called business/IT alignment problem. Solving the business/IT alignment problem requires enterprises to align human, organizational, informational, and technological aspects of systems..."
