Information Structure Viewpoint : Archimate

Concerns: Structure and dependencies of the used data and information, consistency and completeness
Purpose: Designing
Scope: Multiple layer/Single aspect

The information structure viewpoint is comparable to the traditional information models created in the development of almost any information system. It shows the structure of the information used in the enterprise or in a specific business process or application, in terms of data types or (object-oriented) class structures. Furthermore, it may show how the information at the business level is represented at the application level in the form of the data structures used there, and how these are then mapped onto the underlying technology infrastructure; e.g., by means of a database schema.

Service Realization Viewpoint : Archimate

Concerns: Added-value of business processes, consistency and completeness, responsibilities
Purpose: Designing, deciding
Scope: Multiple layer/Multiple aspect

The service realization viewpoint is used to show how one or more business services are realized by the underlying processes (and sometimes by application components). Thus, it forms the bridge between the business products viewpoint and the business process view. It provides a “view from the outside” on one or more business processes.

Physical Viewpoint : Archimate

Concerns: Relationships and dependencies of the physical environment and how this relates to IT infrastructure
Purpose: Designing
Scope: Multiple layer/Multiple aspect

The physical viewpoint contains equipment (one or more physical machines, tools, or instruments) that can create, use, store, move, or transform materials, how the equipment is connected via the distribution network, and what other active elements are assigned to the equipment.

Layered Viewpoint : Archimate

Concerns: Consistency, reduction of complexity, impact of change, flexibility
Purpose: Designing, deciding, informing
Scope: Multiple layer/Multiple aspect

The layered viewpoint pictures several layers and aspects of an Enterprise Architecture in one diagram. There are two categories of layers, namely dedicated layers and service layers. The layers are the result of the use of the “grouping” relationship for a natural partitioning of the entire set of objects and relationships that belong to a model. The technology, application, process, and actor/role layers belong to the first category. The structural principle behind a fully layered viewpoint is that each dedicated layer exposes, by means of the “realization” relationship, a layer of services, which are further on “serving” the next dedicated layer. Thus, we can easily separate the internal structure and organization of a dedicated layer from its externally observable behavior expressed as the service layer that the dedicated layer realizes. The order, number, or nature of these layers are not fixed, but in general a (more or less) complete and natural layering of an ArchiMate model should contain the succession of layers depicted in the example given below. However, this example is by no means intended to be prescriptive. The main goal of the layered viewpoint is to provide an overview in one diagram. Furthermore, this viewpoint can be used as support for impact of change analysis and performance analysis or for extending the service portfolio.

All core elements and all relationships are permitted in this viewpoint.

Stakeholder Viewpoint : Archimate

Concerns: Architecture mission and strategy, motivation
Purpose: Designing, deciding, informing
Scope: Motivation

The stakeholder viewpoint allows the analyst to model the stakeholders, the internal and external drivers for change, and the assessments (in terms of strengths, weaknesses, opportunities, and threats) of these drivers. Also, the links to the initial (high-level) goals that address these concerns and assessments may be described. These goals form the basis for the requirements engineering process, including goal refinement, contribution and conflict analysis, and the derivation of requirements that realize the goals.

Goal Realization Viewpoint: Archimate

Concerns: Architecture mission, strategy and tactics, motivation
Purpose: Designing, deciding
Scope: Motivation

The goal realization viewpoint allows a designer to model the refinement of (high-level) goals into more tangible goals, and the refinement of tangible goals into requirements or constraints that describe the properties that are needed to realize the goals. The refinement of goals into sub-goals is modeled using the aggregation relationship. The refinement of goals into requirements is modeled using the realization relationship.

In addition, the principles may be modeled that guide the refinement of goals into requirements.

Outcome Realization Viewpoint : Archimate

Concerns: Business-oriented results
Purpose: Designing, deciding
Scope: Strategy

The outcome realization viewpoint is used to show how the highest-level, business-oriented results are produced by the capabilities and underlying core elements.

Resource Map Viewpoint : Archimate

Concerns: Architecture strategy and tactics, motivation
Purpose: Designing, deciding
Scope: Strategy

The resource map viewpoint allows the business architect to create a structured overview of the resources of the enterprise. A resource map typically shows two or three levels of resources across the entire enterprise. It can, for example, be used as a heat map to identify areas of investment. In some cases, a resource map may also show relationships between resources and the capabilities they are assigned to.

Project Viewpoint : Archimate

Concerns: Architecture vision and policies, motivation
Purpose: Deciding, informing
Scope: Implementation and Migration

A project viewpoint is primarily used to model the management of architecture change. The “architecture” of the migration process from an old situation (current state Enterprise Architecture) to a new desired situation (target state Enterprise Architecture) has significant consequences on the medium and long-term growth strategy and the subsequent decision-making process. Some of the issues that should be taken into account by the models designed in this viewpoint are:

  • Developing a fully-fledged organization-wide Enterprise Architecture is a task that may require several years.
  • All systems and services must remain operational regardless of the presumed modifications and changes of the Enterprise Architecture during the change process.
  • The change process may have to deal with immature technology standards (e.g., messaging, security, data, etc.).
  • The change has serious consequences for the personnel, culture, way of working, and organization.

Furthermore, there are several other governance aspects that might constrain the transformation process, such as internal and external cooperation, project portfolio management, project management (deliverables, goals, etc.), plateau planning, financial and legal aspects, etc.

Migration Viewpoint : Archimate

Concerns: History of models
Purpose: Designing, deciding, informing
Scope: Implementation and Migration

The migration viewpoint entails models and concepts that can be used for specifying the transition from an existing architecture to a desired architecture.
