Enterprise architectonics as a conceptual device to support a fundamental understanding of enterprise architecture

Evidence of the interest in enterprise architecture (EA) is seen in the number of enterprise architecture frameworks (EAF) in existence. An EAF is responsible for the realisation of an EA, and therefore acts as a container for the terminology of EA. The lack of acceptance of terms and definitions, coupled with the phenomenon of the large number of EAFs, indicate a silo type understanding of what EA is, which leads to a lack of clarity in the conceptual foundations of EA. By following a design science research (DSR) approach, a conceptual artefact (an enterprise architectonic (EAt)) is created to address the lack of clarity in the conceptual foundations of EA thinking and practice. The EAt serves as a conceptual device to represent the fundamental understanding of EA in terms of concepts and their relationships. The content of the EAt is derived from applying a structured interpretation method (SIM) to three prominent EAFs (The Open Group Architecture Framework, the Department of Defense Architecture Framework and the Zachman Framework for Enterprise Architecture). The SIM’s results are an EA understanding that consists of an EA claim:
EA is similar in intent to the enterprise as a worldview is to the world.
It is supported by six EA propositions:
 Proposition 1: EA’s underlying theoretical knowledge is in a pre-suppositional state.
 Proposition 2: EA is a description of the structure of the systems of an enterprise.
 Proposition 3: EA represents the enterprise in time-oriented architectures such as an as-is, to-be and has-been architecture.
 Proposition 4: EA translates the values/strategy of the enterprise into operational systems appropriate to the information society.
 Proposition 5: EA provides a means to manage decisions about the IT/IS management and implementation in the enterprise.
 Proposition 6: EA captures a representation of the enterprise in the form of a model or set of models.
The six EA propositions are analysed through the lens of Heidegger's equipment analysis, to produce a set of architectonic elements. These elements are arranged in the EAt to create a conceptual device to support the fundamental understanding of EA. / Centre for Applied Information and Communication / Ph. D. (Information Systems)
