Agile has a concept called the cone of uncertainty.
The way we use this concept in practice is by doing small chunks and delivering fast, and the more chunks we have done with a project/feature/whatever the more likely our estimates get better over time because there is less work left and we are more familiar with the work now.

- AstralStorm 8y agoSometimes there are no "small chunks" and this is where all agile approaches fail. If a thing does not work it is not a deliverable. Bonus points if the thing is not really testable because it is tied to platform/OS. (And you'd either have to implement it in full our spend weeks implementing a test harness.)
