Investigating Enterprise Architecture implementation in public sector organisation: A case study of Ministry of Health Malaysia

Enterprise Architecture (EA) is gaining its importance and has become significant agenda in any Information Technology (IT) transformation in most organisation. Despite of many EA frameworks and methodologies available, the implementation of EA is a challenging process. Therefore, this paper aims to explore the process of EA implementation in an organisation and to identify its critical success factors (CSFs). An integrated framework comprising of Configurable Process Model (CPM) and Balanced Scorecard (BSC) are used in this study. The findings are categorised into six perspectives which are authority support, internal process, learning and growth, cost, technology and talent management. Based on Ministry of Health Malaysia (MOHM) as a case study, it reveals that every organisation should define and design their own EA solution based on their core business and need. The existence of framework and documentation does not represent the successful EA if it is not being practiced in the organisation. The EA implementation experience and the CSFs discussed in this paper will be valuable guidelines for other EA implementer in other public sector organisation.

Enterprise architecture implementation model: Measurement from experts and practitioner perspectives

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.

A systematic review of enterprise architecture assessment models

This article provides a systematic review of Enterprise Architecture (EA) assessment model. The review main goal is to identify the existing EA assessment models and to categorise the models according to EA phases as well as to analyse the models limitation. The review result shows that there are 16 EA assessment models proposed across both industry and academic areas that fit in three EA phases mentioned.
