The what, why and how of #NoEstimates
I have recently spent some time looking more closely into the #NoEstimates movement. There is a substantial amount of information to be found on the internet, just look it up with your favorite search engine. Ron Jeffries, Woody Zuill, Neil Killick, Steve Fenton, Vasco Duarte, Angel Medinilla and many more share their experience in working with estimates. In this post I would like to share some thoughts with you and try to present the basic ideas conveyed in the “No Estimates” book by Vasco Duarte which I have just finished reading.
#NoEstimates is a catchy, rather provoking, term that questions the practice of estimating software development work. After all, if like Steve McConnell in his “Software Estimation: Demystifying the Black Art” book, you accept that good estimating means being within 25% of the actual duration of a project 75% of the time, would you bet your money on it? I know the #NoEstimates movement people wouldn’t! Instead, they suggest we should stop trying to get better in estimating and start forecasting instead.
