Last month we began our “fight” by exploring two estimating techniques that are often used on both Scrum and Waterfall projects. The first was relative sizing (one kind of analogous estimating) and the second Delphi (called Planning Poker in Scrum). Scrum won both rounds (barely) because although both techniques can be used on both types of projects, their usage in Scrum seems easier to understand, learn, and apply. I don’t know about you, but when I hear the terms Analogous and Delphi I think academics and hard work. When I hear about tee-shirt sizes and planning poker, I think fun.
