The first step in cost-justifying usability engineering on a particular software development project is to lay out a usability engineering plan for that project.

However, it seems that these commonly adopted models do not explicitly cover usability engineering (UE) processes.
Interactive system developers are increasingly including usability engineering as an integral part of interactive system development.
One approach to addressing these difficulties is through appropriate usability engineering tool support.
But whatever those practices, confidence levels, and profiles are, this breadth makes it all the more important to know the costs and benefits of employing usability engineering for the site or application, and the costs of not employing usability engineering.
This chapter presents a framework for cost-justifying usability engineering efforts on software development projects, by describing how to calculate the costs and estimate the benefits of each of the usability engineering lifecycle tasks that can potentially be applied.
The usability engineering lifecycle documents a structured and systematic approach to address usability within the product development process.
This article describes an approach for applying usability engineering methods to the field of industrial system design.
