Introduction

In Information Technology (IT), architects play a crucial role in shaping and guiding an organisation’s technology infrastructure, ensuring alignment with business goals. There are several types of IT architects, each specialising in a specific domain. The Open Group Architecture Framework (TOGAF) is a widely used methodology that outlines the roles of these architects and the processes they follow. This article seeks to illuminate the various types of IT architects and their roles within the TOGAF framework.

Enterprise Architect

Enterprise Architects (EA) are responsible for creating an overarching vision that unifies organisational IT and project strategies. They design a holistic view of an organisation’s strategy, processes, information, and IT assets, ensuring they align with business objectives.

In the TOGAF framework, the EA is often considered the conductor who orchestrates other architects. They are primarily involved in the Architecture Vision and Opportunities and Solutions phases, establishing the direction and identifying opportunities to achieve the enterprise-wide strategy.

Solution Architect

Solution Architects (SA) operate tactically, designing IT systems to meet specific business requirements. They bridge the gap between business problems and technology solutions, ensuring scalable, reliable, and secure systems.

Within the TOGAF framework, SAs play a critical role in the Architecture Definition and Transition Planning phases. They define the solutions to be implemented and create a detailed plan for transitioning from the current to the future state.

Data Architect

Data Architects focus on an organisation’s data infrastructure. They design how data is collected, processed, stored, and utilised, ensuring it is secure, accessible, and reliable. They create data models, set data standards, and govern data assets.

In TOGAF, Data Architects are heavily involved in the Information Systems Architectures phase, where they design the data and application architecture to ensure it supports the business strategy. They also play a part in setting data governance policies in the Governance and Management Framework phase.

Technical Architect

Technical Architects, or Infrastructure Architects, specialise in an organisation’s technology infrastructure. They oversee hardware, software, networks, and other technical aspects, supporting the organisation’s IT strategy and business goals.

In the TOGAF framework, Technical Architects contribute significantly to the Technology Architecture phase, outlining the hardware, software, and network solutions to meet the organisation’s objectives. They also play a role in the Implementation Governance phase, ensuring the technology implementation aligns with the architectural vision.

Conclusion

While each IT architect has a different focus and set of responsibilities, they all work together to achieve a common goal – to align technology strategy with business strategy. The TOGAF framework provides a clear roadmap for these architects, outlining the phases and processes they need to follow. Whether it’s the strategic insight of an Enterprise Architect, the tactical planning of a Solution Architect, the data management skills of a Data Architect, or the technical expertise of a Technical Architect, each plays a vital role in shaping and guiding an organisation’s technology infrastructure.
