I am a software tester for the last 3 years and am being considered for a senior position.
I have been asked to prepare myself on estimation techniques.
I have not done any QA/QC estimation as of yet.
Would you be able to point me to some easy to understand documentation on estimation concepts and techniques?
Check out the essay on "The Test Estimation Process" at http://www.stickyminds.com/sitewide....;ObjectId=3510
This will introduce you to one test estimation methodolgoy.
Keep in mind there are several test estimation techniques e.g. TPA, FPA, WBS etc.
Find out the following:
1) Which are the preferred techniques in your organization?
2) What is the rationale for using a particular estimation technique?
3) What kind of assumptions/ narrative is recorded along with the estimates?
4) Are the estimates and actual data stored? If so, generally how accurate were the estimates?
You will also need a lot of practice in estimation. Always try to compare the actual values with the estimates created by you. Analyze out the reasons for differences. Use this information to further tune your estimation process. Soon, you will figure out an estimation technique that you understand and can trust upon and which works for you.
Hope this helps!

Thank you Inder!
I was wondering if you/others would be able to recommend some good books on the same?

There is so much to consider when trying to estimate for a project. I say ‘trying’ because in my experience, not every thing always goes as planned. [img]/images/graemlins/smile.gif[/img]
I would say that depending on which SDLC method you work in, this would greatly affect the qa estimation, plus skills and experience of team members for a given project.
