 Right the the session hasn't started, but I thought it would be an interesting exercise to do a bit of scoreboarding So I have a question for you, and I would like you to raise your hands if you believe That you must have estimates to correctly manage a project to meet a certain deadline Who believes that having estimates is a must To meet a certain deadline. Could you put your hands up? I'll just quickly try to count you don't put your hands down, please. All right, that's 25 and Related question how many of you believe that estimates can be made accurate up front, obviously not after the fact So if you could raise your hands Can estimates be made accurate? Is it even possible to do that? Can you please raise your hands? Okay, the number is zero Did I get the number right? Somebody object All right. All right final question one one. All right good Okay then the Final question how many of you wish Not that you know how but that you wish you could work and Deliver software and be successful business-wise without estimates I'll just quickly count. Please keep your hands up. Okay. It's about 50 So the challenge for me is to see how these numbers change and How they change so that this goes up this goes down and This goes down
