A tester is designing 3 complex test cases, 5 medium complex test cases and 10 simple test cases each day. The PL has arrived at an estimation where the test cases are normalized to a common value. Each complex test case is normalized to 20 test cases, each medium test case to 10 test cases and each simple test case to 1 test case. What is the productivity test design for the month assuming 4 testers are working in the project and all the testers produce the same no of test cases each day? Assume that the month contains 20 working days.
