I've been a software tester for a little more than a couple of years now and I'm looking to upgrade my skills for the role of Team Lead.
Team leaders and managers usually have to do the planning and estimation for projects. I'm trying to learn these skills.
I feel I'm not able to reliably assess the testing effort in terms of time, resources and cost. I'd be really thankful if I could get some good pointers to help me understand and do the estimations in a better way.
