Abstract
The benefits of a software system are quantifiable relative to the business goals the system was developed to serve. These benefits result form interactions between the system functionality and its quality attributes such as performance, reliability etc. In turn, the system quality attributes are determined mostly by its architectural design decisions.
Hence, this paper seeks to argue that software architecture is the crucial component to study in making design tradeoffs and performing cost-benefit analysis. This paper also presents the Cost Benefit Analysis Method (CBAM), which is an architectural-centric approach to the economic modeling of software design decision-making where costs and benefits are traded off with system quality attributes.
