Estimate the effort needed to perform the task in hours or days (measured in ideal engineering hours, assuming concentrated, uninterrupted work on the task). Don't fall into the trap of estimating in duration—duration estimates will vary wildly depending on how much non-project work the person doing the estimate expects to be doing at the same time.

Tip

Use small tasks

If you find that a work package has an estimate of more than 80 hours, revisit the Work Breakdown Structure and split the task into smaller subtasks. An estimate of 80+ hours very often indicates an incomplete understanding of the task and carries ...
