There are few development organizations that have fully integrated usability activities as an integral part of their product development projects. One reason for this is that the benefits of better usability are not visible for the management. In this paper, the characteristics of selected published usability cost-benefit models are analyzed. These models have different approaches for identifying, approaching and categorizing the costs and benefits of usability. The analyzed models provide general guidelines for estimating the costs and benefits of usability but in most cases provide only little details. It is proposed that the business type of development organization and the type of the developed product as variables could be taken into account when analyzing the benefits of better usability.
