Estimation Techniques

When estimating for a testing project to find out the number of resources needed the below techniques will be used by us:

1. Analogous method – Following the previous history of the estimation

2. Parametric model – Expert judgment

3. 3 point estimate – Optimist, Pessimist and Most likely

4. WBS – Work breakdown structure – Simple, Medium and Complex

I would like to thank Mr.Somasundaram at this time for sharing the estimation techniques knowledge with us.Thanks so much Somas.
