The major hypotheses of this research were partially supported with data collected from a large, technically oriented governmental agency (n = 380).

1977; Dow, 1988).
LITERATURE REVIEW
Very few research studies have attempted tocompare these approaches directly, to assess how they may differ along critical dimensions. A recent attempt to systematically compare formal and informal groupings and their impact on the levels of role ambiguity found more similarities than differences and suggested a complex set of contingencies in which one or the other would have the most impact on organizational variables
