What is Enterprise

Enterprise architecture (EA) is employed primarily to resolve and address factors and challenges, such as complexities, inconsistencies, and disparities, in information systems (IS) and technologies. This includes collaborations, implementations, and integrations of systems and technologies, and the overall governance of the computing environment of an organization including governments' administrations. However, the challenges persist even with the emergence and deployment of EA in organizations. Some of the challenges have cost and affected many organizations in their zeal and goal to compete, realize their investment, and efforts to bridge the gap between the IT and business units. Thus, the deployment of EA to addressing the challenges as stated above needs to be strategically relooked or reengineered. The authors therefore employ the activity theory (AT) as a lens to assess the deployment of EA in an organization. Based on the analysis and assessment, a model that identifies the key influencing factors in the deployment of EA was developed.
