Several (as a rule three-four) optimal test plans can be calculated from the initial data and restrictions given by the customer. The results are presented to the customer (by mail or fax) as a standard print.
The customer should provide the following information:
- the values of acceptance and rejection levels for the controlled reliability characteristic;
- values (wanted range) of producer's and consumer's risks;
- restrictions concerning the maximum allowable calendar test time (the maximum accumulated relevant test time) and the number of products under test.
