How do project managers estimate task duration?
Work within a range (three point estimate) Then, add the times for the best and worst cases plus four times the most likely. Divide by six. This gives you an estimated duration which takes into account the uncertainties of the estimate but weighs the result more strongly towards the most probable result.

- Get the full scope. Before you start doing any calculations in your head to estimate time, get the full details of what’s involved.
- Map it out.
- Figure out your error ratio.
- Add more estimate time for new tasks.
- Track your monkey wrenches.
How does the estimating task durations process work?
The main output of the Estimate Activity Durations process is a duration for each task. When manually developing a project schedule, each activity requires a duration, like this: This is called Bottom Up Estimating, whereby each task is given an estimate and the total is rolled up into the overall project estimate.
How long should a project be tracked in hours?
For small projects less than about 2 weeks in duration, tracking in hours works pretty good. Larger projects will not want to be bogged down by such small units and will need to be tracked in days.
