How does it split the time from the risk? My main problem with points is the impossibility to represent: - A long task of 5 days that's very well known, it's 5 days of work - A short task that's very uncertain. It could be a one line change or many days of work With time range, you can represent that and it's very visible. With points, you can represent that as the same points, but that does not reflect reality, one…
My team uses story points to estimate large projects over long periods of time. Sometimes things are overestimated, and other times things are underestimated. However, when you sum them all together, the errors tend to cancel each other out. I've found that upper management doesn't care whether any given task actually takes 3 days when we estimate it at 3 days. They just want to see a schedule where each task is esti…
