Why Software Estimations Are Always Wrong

Video Description

Software estimation is always wrong, so how can we do it better? Estimating software, or anything else, is always an exercise in guesswork and predicting the future, but for software, it is often even more difficult than for some other things because the very nature of software means that we are always working on something new, that we have done exactly the same before. The very common mistake then when the estimates are wrong is to aim to increase the precision of the estimate this is completely the wrong thing to do. So what should we do instead? In this episode software engineer and author of best-selling books “Continuous Delivery” and “Modern Software Engineering", Dave Farley, explores the vexing problem of estimation, why it is so problematic, and what we can do to increase the usefulness of our estimates. Dave also presents a simple model that can help you to estimate your ideas more accurately, by avoiding the trap of attempting to be too precise. - ⭐ PATREON: Join the Continuous Delivery community and access extra perks & content!
