What is an estimate?
• An approximate calculation or judgement of the value, number, quantity, or extent of something

That’s why they suck!
• Managers love them… and Developers hate them

Why (supposedly) you need them?
• Roadmap purposes?
• “Go / No Go” to create something?
• To have deadlines?

Stop focusing on the wrong thing!
• Estimates don’t mean a lot• Estimates don’t bring value• Don’t decide based on hunches• Decide on ROI and Profit• When was the last time
something was aborted because the team told that it was going to take too long?

Do we really need estimates?
