Principles of cognitive work analysis were directly applied to the conceptualization and design of a web-based software tool for investment analysis. The investment philosophy known as fundamental analysis is concerned with the intrinsic value of a company compared with its stock price. The means-end abstraction hierarchy was critical in characterizing the work domain of the fundamental analyst and allowed an ecological interface on the domain to be constructed. This resulted in a patentable software product which is now on the market.
