Usability Cost Benefit Analysis Using a Mathematical Equation

The software development is a key area in Software Engineering. Several mathematical models have been emerged and implemented for the cost benefit analysis of the software development effort. The most dominant model is Bohem’s COCOMO. On the other hand, Usability is also an important characteristic of the software or system. But, there is no defined mathematical model to calculate the effort spent for the process of usability. However, several theoretical cost benefit analysis models are defined by various authors. The present study is conducted to analyze different usability cost benefit justification models. Further, on the basis of general cost benefit analysis framework by Mayhew, a mathematical model is defined. The purpose of present study is to provide a mathematical equation to usability cost benefit analysis process.
