41. Integrated Architecture Framework
Methods and Tools
IAF is open framework for methods and tools, but they must support the architectural description of:
The four architecture areas
The relations between the areas
Enterprise-level and project-level designs
External, Internal and Life-Cycle Viewpoints
Common Quality Viewpoints such as Cost and Performance
Tools must meet the requirements in the White Paper General Architectural Principles and Concepts
Methods and Tools must be related to the rules and guidelines for architectural design in the reference architectures
