Hackman’s model identifies a causal link between group effectiveness and factors related to the task, group composition, managerial support and processes of the group. The implication is that when these factors are favourable, the result will be a greater level of group effectiveness, determined by such outcomes as the acceptability of the output, meeting of team members’ needs and the continuity of the group. The model asserts that challenge, complexity and interdependence are requisite task characteristics for maximum group effectiveness (for the sake of efficiency and succinctness, it will be assumed henceforth that this is the ultimate objective and justification for recommendations proposed). The rationale is that these characteristics necessarily promote a sense of cohesion and trust within the group due to the fact that tasks of this nature are more effectively accomplished as a group than as individuals
