People are biased to underestimate the time it takes to get something accomplished. The planning fallacy is a term used by psychologists to describe our tendency to underestimate the amount of time it will take to complete a task. The term was first coined in 1977 by psychologists Daniel Kahneman and Amos Tversky.
To combat this it is important to estimate against something. This is called relative estimation. When you estimate against a scale, you are almost certainly going to underestimate more than if you compare it against something you did before. This is one reason Planning Poker is ineffective – it measures against a scale, not past items that have been worked on.
Amplio team estimation takes about 25% of the time that Planning Poker does, is more flexible in situations where expertise on what’s being estimated varies and achieves better results. Amplio Team Estimation derives from Steve Bockman’s Team Estimation and was influenced by James Grenning’s Planning Poker Party (not to be confused with Mike Cohn’s Planning Poker). Amplio extends it to handle more situations.
