How do you arrive at the estimaton of efforts for a
particular function, if you have not worked on that
function testing before and do not have any past experience?

Answer Posted / saket bharti

In this case we will use the data from previous project
whose nature and complexity of work are almost similar to
the new application.We shall give the estimates using those
data with a deviation margin of +-5%. This is the best
possible and accurate estimate which one can give in this
scenario.To be more accurate use the Work Breakdown
Structure to get the estimates on the lowest level of
activity and sum them all to give the final estimate.
