Abstract: | Data collected from field research using structured observations indicate for task communications significant relationships between organization technology certainty (using Perrow's typology) and use of verbal and sign media and no significant relationship with use of object and written media. These data also indicate relationships between technology certainty and stimulus and problem solving communications purposes. Directionality of communications moderates these technology-purpose relationships, even exposing some additional relationships. The last section of this article proposes a reconceptualized model of organization communications, considering technology certainty, member mobility, and leadership style as independent variables and directionality as a moderating variable. |
