Three7Point Estimating is a techni'ue for estimating and planning large pro6ects& -ne of its

"pecifically% to calculate the the probability distribution for the completion dates of the pro6ect% oneneeds to calculate the e&ected va#ue "ean and standard deviationfor the entire pro6ect&

The e&ected va#ue "eanof the pro6ect is simply the su" of the indi#idual e>pected #alues for

Task B (E9) 7 I1&3 days

Task C (E9) 7 1&1O days

ota# 3&ected Proect Duration = 1!1 days

The standard deviationfor the pro6ect can be calculated by calculating the standard de#iation of

each acti#ity% adding up the s)uaresof each acti#ity8s standard de#iation% and then taking thes)uare rootof this sum&
