Estimations and Results

Are we doing the estimations properly? if yes why most of our guys are extending themselves or working late nights to achieve the targets? And It has other side also like team members have more time than actual time. Is this due to our failure in Estimations or due to customers ;-)

Few days back Mubeen asked me about our Estimations. Honestly I don't have any answer for few questions as we too failed many times due to many reasons which resulted/effected to my team to extend their work hours to complete their tasks. Here we cannot blame anyone as everyone is correct on their perception,

Few methods here

Wide Band Delphi - my favorite Estimation method. In this we can involve everyone, taking their opinions. Check the below link for details

Test Estimation Approaches

Test Effort Estimation

Finally on Estimations: There are many techniques, methods defined by our Guru's. But the problem is we do not follow properly.

Testing Effort Estimation

How many of us are not asking the team members to stretch or extend to complete the Task?

I am sure everyone will ask..(:-)

As you all know there is no tool or approach available to give 100% correct estimation for Testing Effort. In My knowledge (my opinion) this will depend on Situation, Project, Resources, Technology. If I am having everything (clear specifications, good resources and required technology) in my hand i will choose WBS for Effort Estimation. If I don't have clear requirements I will say 40% of development Team. I feel I should have thorough knowledge on all approaches and should able to choose the right approach based on the situation.

There are some good links available in net on Software Testing Effort Estimation. Please verify the below links.
