When we first started out building Intervals, we were responding to the lack of applications available that were more than ‘simple.’ We tried running several of these ‘simple’ web-based project management applications, but none of them fit our needs. We need task tracking, time tracking, reporting, and invoicing; the main components of our web development business. What we needed was something in between ‘simple’ and ‘complex’.
Now that Intervals is out there, we are seeing others respond to this need as well. Baekdal.com does a great job at explaining why the ‘simple’ is no longer enough, and why people are gravitating to applications and products that do more, in his post The Secret to Understanding Design.
