September 2002 Presentation
Rick Kazman

The CBAM (Cost Benefit Analysis Method) extends the ATAM framework to elicit and model costs, benefits, and uncertainty.

In any investment you should consider the

  • cost
  • potential benefit
  • risk/uncertainty

How do we quantify these when the investment is software?

The Cost Benefit Analysis Method (CBAM) extends the Architecture Tradeoff Analysis Method (ATAM) framework. The aim of the CBAM is to explicitly associate costs, benefits, and uncertainty with architectural decisions, as a means of optimizing the choice of such decisions.

This 39-slide presentation describes the reasons for using CBAM, the steps involves in conducting this analysis, and the type of expected results.
