As self-described, these frameworks are derived from the common EA effort, in turn referred to as domain specific. By design, they are derived with a predefined set of business conditions and concerns because they may have originated from an Enterprise Architecture team or process improvement effort. On rolling out to the industry, these frameworks are mostly driven by government agencies or other geographies.

Based on the types of industry of the EA Frameworks, the type charter is depicted as follows:

By design, the EA Framework provides a conceptual framework to explain the following:

• How the key terms are related to each other conceptually for architectural description
• The following are the number of scenarios for the enterprise architectural activities during the software life cycle:
  • Evolutionary system
  • Existing architecture
  • Architectural evaluation
• The role of the stakeholders in the creation and use of an architecture description

In this book, we will cover the foundations of two commonly known, general purpose EA Frameworks, which are as follows:

• TOGAF
• Zachman Framework

We will look into their details after the layers of Enterprise Architecture section as follows:
