Enterprise architecture implementation model: Measurement from experts and practitioner perspectives

Abstract

Enterprise Architecture (EA) is vital element for organisation to ensure the viability of the organisation functionality. However, many organisations facing problem in EA implementation due to complexity of the EA frameworks, rigidity of business function and the chaotic IT structure. Various suggestions for better EA implementation in previous studies are yet to be verified by the EA practitioners in real case scenario. Therefore, this paper aims to measure the influential factors in EA implementation process from both experts and practitioners perspectives. This EA implementation model was formulated based on 27 factors from six categories, (IP-Internal Process, LG-Learning and Growth, AS-Authority Support, CS-Cost, TC-Technology and TM-Talent Management) which are gathered from previous studies and case studies of Malaysian Public Sector organisations. To measure this model, survey questionnaire was conducted to both selected EA experts and practitioners with intention to identify any differences between the theoretical and practical aspects in EA implementation. Findings reveal that, there is no significance difference on the level of agreement between the EA experts and practitioners except for three factors which are IP6-Rules and Process, AS5-Political Influence and CS1-Financial Resources. Hence, it can be concluded that both experts and practitioner share the same opinion on the factors that influence the EA implementation process.
