Enterprise Architecture Operating Model

RGP supported the Client in enhancing its Enterprise Architecture (EA) capability to better plan, govern, and execute large-scale transformations. The initiative began with an in-depth analysis of the Bank’s IT organization, including stakeholders, responsibilities, and culture, to develop a TOGAF-inspired taxonomy tailored to the Client’s needs. RGP used this framework to design a Target EA Operating Model, driving cultural shifts toward accountability and adherence to architectural principles. Additionally, RGP facilitated communication, collaboration, and alignment across historically siloed groups.​

RGP deployed a team of Enterprise Architecture experts to assess the Client’s EA function and recommend improvements. Through stakeholder interviews and documentation reviews, RGP identified gaps, pain points, and opportunities within the EA capability. Leveraging industry best practices and frameworks, RGP developed a TOGAF-based EA taxonomy tailored to the Client’s structure, defining IT domains with clear scope and focus areas. This taxonomy served as the foundation for a Target EA Operating Model, establishing domain-specific roles, responsibilities, and governance to enhance architecture oversight and solution implementation across the enterprise.

RGP strengthened the client’s EA function through a multi-prong approach, enhancing governance, promoting collaboration, and defining roles and responsibilities for sustainable change.​​
