What is Estimation by Relative Sizing?
Estimation by Relative Sizing considers the complexity of other tasks is considered while estimating the project. It involves a comparison of the parameters from the current tasks with similar types of tasks to identify and calculate the project efforts. This estimation method does not make it compulsory to find the exact numerical estimate. It estimates the project efforts just by comparing them with tasks of similar categories.
- Estimation by relative sizing includes the comparison of ongoing activities to similar types of activities using the user scenarios and Story Points. It means that the complexity of the user story is compared with the user story of other tasks.
- The user story with the highest complexity is assigned a higher number of story points. Thus, we can compare the project tasks in terms of story points.
Estimation by Analogy and Relative Sizing
Project Managers put a lot of time and effort to successfully deliver the project. What they need is a robust technique to estimate their project. In Project Management, Analogous and Relative-Size Estimation are popular techniques that allow us to predict the efforts required for the project tasks. Also, we can compare the efforts for new tasks with those of completed ones so that we can analyze our workflow efficiency and resource availability.
