Three Point Estimation?
Submitted by: AdministratorThree point estimation is the estimation method is based on statistical data. It is very much similar to WBS technique, task are broken down into subtasks & three types of estimation are done on this sub pieces.
Optimistic Estimate (Best case scenario in which nothing goes wrong and all conditions are optimal.) = A
Most Likely Estimate (most likely duration and there may be some problem but most of the things will go right.) = M
Pessimistic Estimate (worst case scenario which everything goes wrong.) = B
Formula to find Value for Estimate (E) = A + (4*M) + B / 6
Standard Deviation (SD) = = (B – A)/6
Now a days, planning poker and Delphi estimates are most popular testing test estimation techniques.
