Architecture tradeoff analysis method

In software engineering, architecture tradeoff analysis method (ATAM) is a risk-mitigation process used early in the software development life cycle. In software engineering, architecture tradeoff analysis method (ATAM) is a risk-mitigation process used early in the software development life cycle. ATAM was developed by the Software Engineering Institute at the Carnegie Mellon University. Its purpose is to help choose a suitable architecture for a software system by discovering trade-offs and sensitivity points.
