Evaluating the Realization of Benefits from Enterprise Architecture Management - Construction and Validation of a Theoretical Model

Zusammenfassung / Abstract

Enterprise Architecture Management (EAM) is an intensively discussed approach in industry and academia, which aims to facilitate the management of business transformations. The core of EAM is thereby to holistically understand, engineer, and manage an organization’s business transformations according to its business strategy. Despite the popularity and potential of EAM, both researchers and practitioners lament a lack of knowledge about the realization of benefits from EAM. To determine these benefits available through EAM, we explore various success dimensions of the EAM benefit realization in this doctoral thesis. To this end, we develop and test a model that explains the role of the success dimensions in the realization of benefits from EAM.

The proposed EAM Benefit Realization Model is based on the DeLone & McLean IS success model, the findings of an extensive literature review, and eleven exploratory interviews. To further test this model, we operationalize it as a measurement instrument based on a Web-based survey. We demonstrate the strong reliability and validity of this measurement instrument in pre-tests and a pilot, and use it subsequently to collect data in a global survey. Based on the collected data from 133 EAM stakeholders, we conduct a confirmatory factor analysis that confirms the existence of an impact of five distinct dimensions on the benefits derived from EAM: ‘EAM product quality’, ‘EAM infrastructure quality’, ‘EAM service delivery quality’, ‘EAM cultural aspects’, and ‘EAM use’.

The findings presented in this thesis demonstrate that direct EAM benefits are realized from the two success factors of ‘EAM product quality’ and ‘EAM use’. Furthermore, the ‘EAM cultural aspects’ are a central enabler in realizing EAM benefits from the dimensions of ‘EAM infrastructure quality’ and ‘EAM service delivery quality’.
