Jeff Atwood: “It’s a tremendous credit to Joel Spolsky that he made this crucial feature the centerpiece of the new FogBugz. I’m not aware of any other software lifecycle tools that go to such great lengths to help you produce good estimates.”

Rafe Colburn: “We’re rolling out FogBugz 6.0 at work, and I’m finding that I actually like the time tracking. For one thing, it’s a tool for focus. When you kick off the timer on a task, you don’t want to jump around and multitask because it will just throw off the timer. The timer feature itself is pretty easy to use.”

Scott Rosenberg: “What’s most interesting about the new FogBugz is what Spolsky and his team are calling ‘Evidence Based Scheduling…’”

Reg Braithwaite: “I built a prototype that did the exact thing that FogBugz is doing quite some time ago. However, prototypes are not shipping products. FogBugz is a shipping product. My prototype was not. And that makes all the difference.”

Also: I wrote an earlier article describing Evidence-Based Scheduling, which was in Better Software Magazine last March.
