STAREAST 2009: Test Estimation: Painful or Painless?
As an experienced test manager, Lloyd Roden believes that test estimation is one of the most difficult aspects of test management. You must deal with many unknowns, including dependencies on development activities and the variable quality of the software you test. Lloyd presents seven proven methods he has used to estimate test effort. Some are easy and quick but prone to abuse; others are more detailed and complex but may be more accurate. Lloyd discusses FIA (finger in the air), formula/percentage, historical reference, Parkinson's Law vs. pricing, work breakdown structures, estimation models, and assessment estimation. He shares spreadsheet templates and utilities that you can use and take back to help you improve your estimations. By the end of this session, you might just be thinking that the once painful experience of test estimation can, in fact, be painless. Useful utilities will be given out during the session to help with estimation.
