5.7.2 Training Test Users

Should test users hit your system cold or should you teach them about it first? The answer to this depends on what you are trying to find out, and the way your system will be used in real life. If real users will hit your system cold, as is often the case, you should have them do this in the test. If you really believe users will be pre-trained, then train them before your test. If possible, use the real training materials to do this: you may as well learn something about how well or poorly it works as part of your study.
