“As Rich Internet Applications become more advanced, the tasks, problems, and processes they address become increasingly complex, making it more important than ever to accurately model user workflows. Early Internet applications were often narrowly focused in scope, and the steps were relatively simple and sequential, for example, purchasing items through simple e-commerce, reserving hotel rooms, or renting cars. But as productivity applications move toward a web-based distribution model, the tasks become more complicated.” (David Hogue – Macromedia) – courtesy of jane wells
