An effectiveness model for enterprise architecture methodologies

Abstract

Enterprise Architecture (EA) is employed by enterprises for providing integrated environment to support thealignment of enterprise’s business and Information Technology (IT). EA Implementation Methodology (EAIM)provides methods for managing, developing, and maintaining EA implementation. Several EAIMs have beenproposed in literature; however effectiveness of EAIM has mostly been anecdotal, and research on this subjectis still scant in the academic circles. This research is a survey study on the factors that affect the effectivenessof EAIM using quantitative approach. This study aims to explore the factors that affect the effectiveness ofEAIM and proposed the effectiveness model for EAIMs. The exploratory factor analysis highlights a specificset of five factors: alignment, adaptiveness, support, binding, and innovation. The regression analysis showsthat there is a statistically significant and positive relationship between each of the five factors and the ef-fectiveness of EAIM. The findings contribute to the measurement of the EA implementation’s effectiveness byproviding an indication of the measurement implementation approaches which is used by the EA practitioners.Moreover, the proposed model can be used on developing an effective EAIM.
