Manoj - I'm not sure if I understand your question. Are you looking for sample metrics related to how much time is spent at each phase?
Life should NOT be a trip to the grave with the intention of arriving safely in an cool and well preserved body, but rather to skid in, chocolate in one hand, beer in the other, body wrecked, totally worn out and screaming WOO HOO what a ride!
I usually guestimate the testing breakdown to be 30% during the SDLC design phase to work out the test design, 30% during the SDLC coding phase to build the test scripts and the data, and 40% for the execution of tests (some of which can happen during the SDLC coding phases if you help with unit testing and code integration).
For regression testing that changes to 15% impact analysis, 15%-25% test script updates and added new scripts as required, while 60% - 70% of the effort deals with script execution. These may be reasonable estimates to use for exploratory tests as well, although I personally do not have a lot of statistics on that kind of testing.
