# 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 formula Estimated hours 16 12 30 (N + O + P)/3 (16 + 12 + 30)/3 = 19 hours.

## PERT estimation

 Normal(N) Optimistic (O) Pessimistic (P) Estimation formula Estimated hours 16 12 30 (4N + O + P)/6 (64 + 12 + 30)/3 = 18 hours.

## Standard deviation

 Normal(N) Optimistic (O) Pessimistic (P) Standard Deviation (Formula) Standard Deviation 16 12 30 (P - O)/3 (30-12)/3 = 6 hours 16 12 30 (P - O)/6 (30-12)/6 = 3 hours
