3 point and PERT estimation technique in Agile





  1. 3 point estimation
  2. PERT estimation.

Scenario




  1. How much time will it take to complete the task in the normal scenario?
  2. How much time will it take to complete the task in the best case scenario?
  3. How much time will it take to complete the task in the worst case scenario?



3 -point estimation




Normal(N)Optimistic (O)Pessimistic (P)Estimation formulaEstimated hours
161230(N + O + P)/3(16 + 12 + 30)/3 = 19 hours.



PERT estimation




Normal(N)Optimistic (O)Pessimistic (P)Estimation formulaEstimated hours
161230(4N + O + P)/6(64 + 12 + 30)/3 = 18 hours.



Standard deviation




Normal(N)Optimistic (O)Pessimistic (P)Standard Deviation (Formula)Standard Deviation
161230(P - O)/3(30-12)/3 = 6 hours
161230(P - O)/6(30-12)/6 = 3 hours
