Time-boxes are not estimates

The time-box is an integral part of the idea of sprints, popularised in Scrum and (latterly) by the Google Ventures design process. In creating a time-box, though, we are saying, “We will only spend [some amount of time] on this” not “it will take us [some amount of time] to do this”.

This is a subtle difference: time-boxes are a budgeting tool not an estimating tool; the maximum amount of time we will allocate to achieve a particular outcome or objective.
