It involves the whole team, which initially reviews and discusses the entire backlog. Then, team members sort user stories into groups or columns based on their relative sizing without assigning specific numbers yet. Each column represents a size such as small, medium, or large. Team members can move stories between columns until a consensus is reached. At the end, numeric point values are assigned to each level. Affinity Estimation enables the entire team to estimate work effort collectively, provides high-level sizing for long-term planning, and promotes shared understanding of the backlog contents and priorities.
Guide on Affinity Estimation
What is Affinity Estimation? Affinity estimation refers to a technique used in agile project management. It's particularly beneficial in the early stages of project scope planning, by helping quickly assess the scale and complexity of various tasks.
Why is it important? Affinity estimation is crucial because it allows for swift, group-based estimates, providing broad ballpark numbers of effort for large number of stories, which can be better defined in a rapid manner. It promotes collaborative estimation and discussion which leads to a more accurate scope.
How does it work? In an affinity estimation exercise, tasks are grouped into categories based on relative size. T-Shirt sizes or Fibonacci sequence (1,2,3,5,8,…) can be used as a metric. Team members discuss, sort and assign tasks into these categories, ensuring everyone has a shared understanding of what each task entails.
Exam tips: Answering Questions on Affinity Estimation 1. Remember the purpose: The main goal of affinity estimation is to get a quick, high-level estimate of a large number of user stories or tasks. 2. Know the process: Be sure to understand the different steps involved in affinity estimation: preparation, discussion, sorting (Bucket System or Silent Sorting), and review. 3. Remember its value: Keep in mind that affinity estimation's strengths come in early project planning, and in fostering a collaborative environment. 4. Practical application: You may get scenario-based questions. Practice using affinity estimation in various contexts to be better prepared for these.
