My name is Andrea Richeson. I have worked in web design and development for Texas state government for several years and am currently a graduate student at the University of Texas School of Information. I am working with Dr. Randolph Bias, Dr. Eugenie Bertus, and Jana Tate to co-author a book chapter on the use of return on investment (ROI) methods for justifying usability support for Web site and Web application design.
We'd like to enrich the chapter with your success stories, opinions, and experiences.
ROI Definition
Return on Investment is a percentage return based on capital invested. To establish return, one must measure costs and benefits. Costs might be estimated in a variety of ways. For example, by taking a loaded salary per hour and estimating effort needed per usability task. Benefits might also be measured in a variety of ways, for example, by estimating impact on sales or development cost reductions. ROI might then be calculated using measurements such as internal rate of return (IRR) or net present value (NPV).
