This project was the first in System Architecture Virtual Integration (SAVI) program.
The goal of the project was to shift architecting, design, and production activities to explicitly address integration issues early, reducing program execution risks, cycle time and cost. Activity focused on adopting and developing integration-based software and system development processes with emphasis on integrating Component-Based, Model-Based and Proof-Based Development. Design & production was based on early and continuous integration as virtual models move toward physical systems.
Using these system development processes, developers should be able to
- Specify a system’s architecture and verify its behavior with only partial knowledge of components allowing virtual integration before any components have been built.
- Specify the requirements that a system must impose on a component if it is to meet the overall system requirements.
- Determine if a component meets those requirements.
With these aims in mind, project participants defined the content and schedule for 8 work packages to be accomplished over an extended period of time.
Rapid technological advancement and obsolescence combined with increasingly complex hardware and software evolution presented integration problems affecting all aerospace organizations. The problem was rapidly getting worse. Those affected realized
- They could not afford to solve the problem alone.
- The industry could not afford to solve the problem multiple times.
- No organization could afford not to solve it.
These realizations led to the establishment of the SAVI program and its concept of Integrate then Build.
