Iterative approach for test estimation

In this approach for large test efforts, an initial rough testing estimate is made. Once testing begins, a more refined estimate is made after a small percentage (e.g., 1%) of the first estimate’s work is done. At this point testers have obtained additional test project knowledge and a better understanding of issues, general software quality, and risk. Test plans and schedules can be re-factored if necessary and a new estimate provided. Then a yet-more-refined estimate is made after a somewhat larger percentage (e.g., 2%) of the new work estimate is done. Repeat the cycle as necessary/appropriate
