Why Johnny Can't Estimate? (Update)

Herding Cats

There is a discussion of the conjecture that estimates are a waste, estimates can't be done, estimates are evil, estimates must be stopped immediately. In our domain of engineered systems, there is a broad range of problems, complex issues, approaches to solving problems. illities are a waste.

Since all risk comes from uncertainty - reducible (Epistemic) and irreducible (Aleatory), estimating is a foundation of all we do. There is no discussion of the conjecture that estimates are a waste, estimates can't be done, estimates are evil, estimates must be stopped immediately. illities are a waste.

4 Fallacious Reasons to Estimate and Why Those Are Fallacious

Herding Cats

There's a recent post titled Four Fallacious Reasons to Estimate.

Thinking By Sprinting: What Cognitive Science Tells Us About Why Scrum Works

Scrum.org

Software development is (generally speaking) very complex. Using the aforementioned cognitive limitations, I will argue that approaches based on a fully rational analysis (e.g. Why our brain is not built for software engineering. This will affect all estimates and predictions. waterfalls) are very likely to fail.
