"I'd go so far as to say that I've never heard of a company who got this working before, so if that is the case then Pivotal are clearly doing something right."

I hadn't really seen it before either, TBH. It is not perfect - sometimes we ship late. But that's part of the culture - Pivotal Tracker (www.pivotaltracker.com) tells you the date you're expected to ship given the work you have left, you don't tell it when to ship ;)

Management won't break people over a deadline, they'll generally slip the date. Sustainability is more important.

We do have a small/growing office in Sydney with a few openings: http://pivotal.io/locations/sydney
