Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

According to the common planning Practice, Earned Manhours = Actual Progress % " Monthly or Weekly " X Planned Manhours for the same scale and same period. 

 

It is an indication, how much you must spend from your budgeted Mhrs at that achived Actual progress.

Bo,

In simple terms;

The earned manhour is the project original estimate. The actual manhour is the final cost of the project. Again, refer to the "tea cup" example: if the two men expend 350 to wash the tea cup and report 100%, then, the total project cost is 350 hours, while the original estimate for the project is 100 hours. I hope this makes sense.

Cheers

Thanks for your excellent example, which make the difference very clearly.Also Could I consider that the actual manhour is to the project duration while the earned manhour is to Project cost,is this right?

Good and simple way to differentiate between actual estimated man-hours

Hi Bo,

Consider this scenario:

You have estimated that washing a tea cup will take 10 hours. You have two men to wash the tea cup. They finish their shift and report 10% progress after booking 2 hours for the job.

2 hours is the actual hours, 1 hour (10% of 10 hours) is the earned manhour. I hope this helps.
