Estimate Story Size by Playing Agile Planning Poker

Over the years that I’ve been leading software development projects, I’ve used a number of methods including comparison of projects of similar size and complexity, Microsoft Project, Function Point Analysis or even simply guessing. There have been a few other trendy and perhaps oddball approaches thrown in for good measure. Curiously, regardless of method, the results have tended to be pretty much the same. There has, however, been one exception. I’ve gotten noticeably better results with Agile methods using Agile Planning Poker.
