Last night I heard Mike Cohn speak about Agile Planning and Estimation. Mike’s a great speaker who I highly recommend to you seeing, but you may know him from his company, Mountain Goat software, or his book, User Stories Applied.

Though I’m lucky enough to practice many of the items he spoke about, my most favourite emphasised points of the night included:

• Focus on accuracy over precision;
• Avoid measuring items that are more than a magnitude apart; and
• Measure size over duration.
