The centers on system team interactions designed to reduce the time required for team interpretation while maintaining the superiority of team procedures in the accuracy and completeness of the imagery information extracted. Three experiments were conducted, using the common procedure of having each team member in two-man teams check the interpretation of his teammate. Three specific primary objectives were established 1 To determine the amount and type of knowledge which the checker should have of the initial interpreters work 2 To determine whether the initial interpreter can accurately judge when his work needs to be checked by his teammate and 3 To determine how best to utilize a third man to resolve disagreements among teammates on interpreted items. Variations in procedures were achieved for analysis by setting up four phases or modules of interpreter team activity. Team results produced under each method were assessed in terms of completeness, amount of error, accuracy, and efficiency. Findings suggest that 1 more complete results are produced with higher efficiency in teams where the checker has full knowledge of the initial interpreters work 2 only limited judgment as to the adequacy of their interpretations can be made by initial interpreters 3 team performance increases in completeness but decreases in efficiency with the introduction of a third man 4 results with different team methods pose a tradeoff situation, since no one method appears to hold best for team performance under all requirements.
