How often do we hear “We don’t have time for analysis—let’s just get the project done!” Or “Modeling?! That’s so 1990s.” Or “Modeling is the developer’s job. Yours is to get the requirements.” Or “We’re doing Agile. Requirements evolve, so let’s not waste time with use cases or process models.” We have often heard every argument under the sun why spending time modeling requirements wastes time. However, we believe that modeling actually saves time.

Prior to the creation of something as potentially complex and ubiquitous of a website, an analyst must create a thorough, precise set of requirements in consultation with the right subject matter experts and business stakeholders.
