Gartner has created an excellent view of Enterprise Architecture. This view (shown above) describes how the Architecture can fall into four main quadrants (Gartner is famous for its “Magic Quadrants” !). These quadrants are described by their relationship to being Tactical vs Strategic, and Local vs Enterprise., which are represented along the X and Y axes:
- Enterprise - this is an architecture that spans the entire organization, regardless of department. It should envelop the Strategies and Capabilities that the Enterprise wishes to achieve.
- Local - describes an architecture that is more subjective, perhaps being an architecture for defining the individual systems that the IT Department uses.
- Strategic - these architectures are designed to line up with the Enterprise’s Strategies and Capabilities.
- Tactical - these are architectures which align to objectives.
The Navigate method of applying the TOGAF architectural framework follows this model fairly well. And one of its principles is to understand who the members of the Enterprise Architecture team are, and how they participate. This should include stakeholders from the Enterprise, as they typically provide the Strategies which Enterprise Architecture should be delivering upon. In the Navigate method, there is an exercise which helps understand where on this canvas the individual members lie - which helps understand their role and what they deliver.
Of course, everybody wants to be the Enterprise Architect. But if we examine what the members do, we can derive how they fit. In terms of the Canvas, the four quadrants are first bisected by a line which defines Vanguard Architecture vs Foundational Architecture.
- Vanguard Architecture - this is the innovative, forward-looking architecture. It commonly looks for new ways to achieve the Strategy of the Enterprise. It will examine new technologies and methodologies. In Gartner’s view, this is the Architecture that considers the Capabilities of not only the Enterprise, but those of its Customers, Suppliers and Competitors. This is referred to as “Outside-In Architecture”.
- Foundational Architecture - this tends to be thought of as more of a Traditional way of looking at ONLY the Enterprise and its capabilities, often re-defining Services to be more efficient. This is referred to as “Inside-Out Architecture”.
The two dashed red lines describe the traditional Roles within the Architecture realm. Many Enterprises are moving away from a model where there is a discrete group of Architects that participate in the Architecture field, and move towards a more Federated or Social model. This implies that the Architecture group is such more broadly defined, just as their roles need to be.
- Enterprise Architects - look at the Enterprise holistically, helping the Enterprise understand how to change to suit an ever-changing landscape. They build out the Conceptual Architecture required for transformative change.
- Principal Architects - typically are Solution Architects, but tend to look less at the entire Enterprise, and more at individual Lines of Business. They look after an individual set of Capabilities.
- Solution Architects - tend to be Project-focused, with a solid understanding of the systems which provide the Services of the Enterprise. They build out the Logical Architecture, defining how systems will deliver the Services, and their requisite Functional Requirements.
- Technical Architects - also Project-focused, they develop the Physical Architecture by interpreting the Logical Architecture and applying the Non-Functional Requirements required to satisfy the Solution.
A solid Federated Architecture will have members that fall across all of the quadrants, delivering highly valuable architecture that delivers the Business Outcomes that are defined in the Strategies. This will in turn provide a high degree of traceability from the Stories and Activities defined in the CLIP Framework all the way back to the Business Outcomes.
