People are biased toward underestimating the time it takes to accomplish something. The planning fallacy is a term psychologists use to describe this tendency. It 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.
