As a client, when you pay someone to develop a project for you, you probably don’t care how they do it, as long as it gets done. But what we’ve come to learn over the years is that “done” is a term people interpret quite differently. For example, many clients consider a web project to be finished when the front-end looks as they expect and the functionality is right but a good developer should consider a project complete only after climbing at least two more steps on the Design Hierarchy of Needs: reliability and usability.
