Ensure everyone speaks the same language 2. The scope of a solution architecture is typically limited to a single project, documenting how a system or business solution will be implemented and used by the personnel deploying the system to inform the development, implementation, and operations and maintenance phases of the SDLC [38]. Security is considered in the Information System Architecture phase (phase C) in TOGAF (TOGAF, 2009). During the late 1980s, John Zachman (1987) applied the notion of architecture to represent the functioning of an enterprise, specifically within the context of the enterprise IT landscape and the business environment.

Understanding scope and governance is important, because clearly, if parts of the organization can do what they like, then there is little value in an Enterprise Architecture. The implementation of the third guideline, fostering participation, is provided by three further building blocks, as shown in Table 1-3. Guidance surrounding this implementation are often known as enterprise architecture frameworks (EAFs), which we are exploring from a high level in this article.
