They're just not hour estimates, they're ballpark. We use hour, hours, day, days, week, iteration, iterations. Is it gonna take less than a unit of time or multiple? The harder effort is narrowing down the hourly estimate before beginning work, for scrum. Most of the time you dont know what you dont know, especially when working on large code based with team turnover. Additional complexly comes from attempting to estimate for multiple people at once, like designers, architects, UX, devs, QA, business proxy and interactions with other groups or even 3rd parties.Karlhttps://www.blogger.com/profile/08857379062217922195noreply@blogger.comtag:blogger.com,1999:blog-5028009537158799436.post-47049857591008289232011-06-21T17:51:36.515-07:002011-06-21T17:51:36.515-07:00Cool, thanks Jonathan.

I'll look into it some more.Jim Birdhttps://www.blogger.com/profile/17371102366836131341noreply@blogger.comtag:blogger.com,1999:blog-5028009537158799436.post-85208746163538684472011-06-21T09:19:28.310-07:002011-06-21T09:19:28.310-07:00Good post.
