Guide for Affinity Estimating
Affinity Estimating is an important topic for PSM I, not only in the working world but also in exam scenarios.
What is Affinity Estimating?
Affinity Estimating is a technique used in agile project management to create estimates of the time and effort a project will need. It involves breaking down a project into user stories or tasks and grouping these into categories based on their size or difficulty.
Why is it Important?
It is essential because it allows for a more precise approximation of the time and resources that a project will demand. This aids in planning and resource allocation, helping to mitigate risks related to project overruns.
How does Affinity Estimating Work?
In Affinity Estimating, project tasks are written on cards. Team members collectively decide where the card belongs in predefined size categories usually labelled with t-shirt sizes (XS, S, M, L, XL). The discussion that takes place promotes a shared understanding.
