What Are the Characteristics of a Good Estimate?
Estimates need to reflect reality. Some basic characteristics of what we need from estimates include:
- The estimates consistently reflect the capacity of the Team to deliver.
- The estimates consistently reflect the size of the work no matter what kind of work it is. For example, it should not matter that we are estimating a new feature or defects.
- They are truly relative in that, on a Team by Team basis, an 8 is an 8, and an 8 is about 4 times a 2 no matter the source.
- Estimation data allows the use of ranges of estimates to help understand the risk profile of the work. A simple example of this is when the Product Owner uses best, average and worst velocities to understand what is likely to happen with their plan.
It is worth saying again:
The estimates consistently reflect the capacity of the Team to deliver.
They must be based on reality.
