Why a New View?
• Current architecture products are fragmented into different views making an understanding of the enterprise difficult to grasp, especially for executives
• Typically overview OV-1 and SV-1 are overly simplistic, while other views too microscopic; hence: ”can’t see the forest for the trees”
• Desire to show key components of the enterprise and relate to functionality and performance
• View facilitates an understanding how subsequent enhancements impact functionality and performance

Summary
• New high-level enterprise view consisting of summarized performance, functionality, and services/systems related by traceability indicators with change/enhancement markers
• Can be harmoniously integrated into existing MODAF/DODAF frameworks & toolsets.
• Sequence diagrams enhance “the view”
• Additional tailored architecture views may be added to further improve understanding and achieve tighter integration with requirements
• Purpose: Reusable products; facilitate communications across the team; improved executive-level understanding of the enterprise
• Goal: Higher customer acceptance and usability of architecture products
