The TOTE model is the basic unit that NLP uses for strategies. TOTE stands for Test Operate Test Exit. It takes any procedure as a black box. The first test is to see whether it makes sense to start the procedure. The final test is to check whether the outcome is correct of faulty. In the latter case the TOTE model uses feedback to let the Operation know that something has gone wrong. For that reason is feedback always negative in NLP. If the outcome is correct control is passed on to a different Operation through the Exit. One can praise such an outcome and give a compliment, but that has nothing to do with feedback. As you can combine a single TOTE unit with another, one can see a person as a single TOTE black box.

What we do. — What we do is never understood, but only praised and blamed.
