Planning game: agile estimationΒΆ

Tags: zestsoftware, plone

We just finished estimating a new project at Zest software. With a new method that we all liked quite a lot. It was fun :-)

Agile estimation

The basis is of course that you chop up the project in smaller parts. We're using extreme programming, so we call them stories. A story shouldn't be too big, definitively not more than 8 days. We all got a stack of post-its with 1, 2, 3, 5 and 8+ written on them. A story is read and we all put our estimate face-down on the table.

Show the estimate. If there's a big difference, discuss the story a bit more, telling why you think it takes just a day when the rest estimates 5. Or the other way around. Then put in your face-down estimates again, uncover them and take the average.

Agile estimation

A fun way of doing estimations. And I think you get real good estimates this way. And yes, 1, 2, 3, 5 and 8+ mean you miss the 4 and so. It forces you to make choices. Which helps (according to my feeling).

We've tried this at teamrubber, it does work well, especially as it minimises developers infecting eachother with good/bad feelings about components.
