Tip 16Use the Divide-by-Two Approach to Reduce Iteration Size

If your iterations aren’t succeeding, try the divide-by-two approach. Divide your iterations by two. If they’re six-week iterations, make them three weeks. If they are four-week iterations, make them two weeks. If they’re two-week iterations, make them one week. Smaller iterations help you gather feedback faster about what people actually do in that timebox.

Once you know what people are doing in the timebox, you’ll know whether it’s an estimation problem, a multitasking problem, or some other problem. You can then remove that obstacle. But longer iterations mask the problems.
