Investing in Requirements Analysis In my experience as a usability engineering consultant, requirements analysis is still often a hard sell. While clients understand design, and seem to intuitively grasp the value of objective usability testing, they are often impatient to get to design, and reluctant to invest time and money in requirements analysis. Or, they believe they already understand requirements, through traditional systems analysis techniques. My goal in this article is to demonstrate the importance and payoff of investing in usability requirements analysis tasks by providing real world examples of the results of investing - or not investing - in this part of the Usability Engineering Lifecycle.
