Estimating User Stories
Estimating stories is an important activity that allows us to forecast the work to be completed. The goal of estimating User Stories is to understand the complexity and size of each story while also accounting for the knowledge and uncertainty the team may have.
It is important to point out that estimation should be done by the team who is doing the work, not a Manager, an architect, or even an individual as it negates the benefits of the team having a shared understanding of the work and improved accuracy of the estimate by inclusion of all perspectives.
There are different techniques and approaches to estimating User Stories. The most common are as follows:
- Story Points: This technique is based on the relative scale of complexity and effort required to complete a User Story compared to other User Stories. The team assigns a numerical value (e.g., 1, 2, 3, 5, 8, or 13) to each story based on its complexity, effort, and risk.
