Over the last two decades competition amongst organisations including financial institutions has increased tremendously. The value of information is critical to competition in different organisations. In addition, the management of cost of delivery and cohesiveness of information flow and use in the organisations continue a challenge to information technology (IT). In an attempt to address these challenges, many organisations sought various solutions, including enterprise information architecture (EIA). The EIA is intended to address the needs of the organisation for competitive advantage. This research article focused on the role of principles in the development and implementation of EIA. The article aimed to investigate how EIA could be best leveraged, exploited, or otherwise used to provide business value. The research brings about a fresh perspective and new methodological principles required in architecting the enterprise information.
