The objectives of this study were to survey state-of-the-art media selection methodologies, to evaluate the techniques currently being applied to naval air training programs, and to present three of the techniques to the Naval Air Systems Command NASC, who would select one for implementation and incorporation into a media costs handbook. Media selection methodologies were surveyed, and the following three were selected to represent the state-of-the-art 1 the Training Effectiveness and Cost Effectiveness Prediction TECEP technique, 2 a computerized technique using logic similar to TECEP, and 3 small-group process called the DELPHI method. The latter was included by direction from NASC because of specific interest in exploring its possibilities as a technique that is as efficient and as valid as the other techniques, and because of its perceived potential for minimizing subtle biases. After a review of the three methodologies, NASC selected the DELPHI method for test case evaluation. The results indicate that any future use of the small-group process as a media selection technique will require more specific rules than those used during the test case evaluation. Further, the more rules and assumptions stated, the closer the DELPHI method resembles the more algorithmic techniques surveyed. The conclusion reached was that the DELPHI method, in fact, suffers from the same deficiencies as any other media selection technique, even when the ground rules and assumptions have been specifically stated.
