Guidelines for using points to estimate tasks
Estimates don’t need to be accurate, they need to be consistent. Our velocity corrects for the inaccuracy of our estimates. Estimates on tasks are meant to be relative to other estimates on tasks. When we think of an estimate, we need to compare the tasks to other tasks in the past in order to evaluate consistently.
The smallest unit of work. A task that has been done many times and is not dependent on any other people. No review required.
A task that is fully known and has been done before. May require a review before being complete.
A large task which you feel comfortable completing. This maybe something you have not done before but is not very complex.
A task that has external dependencies or multiple people. May require you to research an aspect of this task.
A complex task which you have not done before and has external dependencies. This task may require pairing with another person.
You’re doing this wrong. You should consider splitting this task into smaller tasks. If you cannot split this then this task should be completely unknown.
