Estimate Goat will give you estimates with the same amount of thought that often goes into project / design / requirement conception (i.e. very little, and somewhat random).
Estimate Goat can be configured to use units you choose, e.g. story points, days, months or years.
** Note: Estimate Goat is not intended for real use, this is purely for entertainment purposes to keep you occupied during boring iteration kick-offs and project scoping meetings. Think of it as a magic 8-ball -- i.e. don't rely on it for real-life questions.
Whilst this was intended for agile / lean / scrum / xp software projects, similar concepts apply to other development methodologies.
