How do you calculate the man hours after calculating function points in fpa / in wbs

P: 1
Hi,

I am a programmer new to project management arena.My question is, how do you estimate total man/hours required for completing a project using function point analysis? I have already calculated total number of function points. Is there any way other than depending upon historic data? How do you do this using wbs?

I have gone through many resources on this. None gives a clear answer to my question. Your help is highly appreciated.

Thanks in advance.

There is a PERT (Program Evaluation and Review Technique) formula to estimate and calculate duration D per function point is

D = ((1 * OD) + (4 * ED) + (1 * PD)) / 6 ; where

OD is Optimistic Duration - Estimate minimum amount of time it would take to perform the task
ED is Expected Duration - Estimate expected amount of time it would take to perform the task
PD is Pessimistic Duration - Estimate maximum amount of time it would take to perform the task

Also keep float (slack) which the amount of time work can be delayed for individual FPs as well as total float.
