Dynamic Metamodel Approach for Government Enterprise Architecture Model Management

Abstract

Enterprise Architecture (EA) is widely adopted by many organisations to align their business and IT together to ensure the resources optimization is achieved. This recent EA development not only brings positive impacts to the business organisation but the government organisation as well. Nevertheless, during the implementation of EA, one of the challenges is to create a standardised and dynamic metamodel that able to integrate the government agencies business models. To date, it is still yet to find any dynamic metamodel that designed for this purpose. Therefore, this paper aims to propose an EA dynamic metamodel design based on complex cognitive activities (CCA) concept. This study starts with an investigation of EA metamodel concept and current practice through literature review and preliminary interviews, followed by the design on EA dynamic metamodel for government agencies with a selection of Malaysian education EA Reference as a pilot case study. As a result, a Dynamic EA Metamodel by using CCA concept is proposed by utilizing the four layers of dynamic design using cognitive action (physical, perceptual, functional, conceptual) and Archimate generic metamodel schema. This is a new contribution to EA Body of Knowledge (EABoK) and EA practice as it helps for better management of EA models especially for a large and complex organisation of the government sector. This model will allow the EA team in multiple organisations to design and develop their EA models according to their own business process but yet still following the EA metamodel set by the top EA office.
