Abstract
What leaders currently know about the topic of group cohesion and performance is a reflection of the literature as studied from a group-level basis. The literature has clearly asserted that group cohesion positively impacts group performance when the group is collectively studied. Greer (2012) noted individual-level analysis was needed to extend the literature on this topic. The current study serves two purposes. First, this study’s design supports research to examine the correlation between group cohesion and group performance in all stages of Tuckman’s (1965) group development model from an individual-level perspective. This view of group development, as seen from the individual’s perspective, provides leaders with valuable insight about the group life cycle at the point at which cohesion occurs. Providing leaders with the perspective of when and to what degree cohesion occurs within group development contributes to a leader’s ability to influence, motivate, and enable organizational success. Second, the study’s research design uses the Group Life Cycle Cohesion and Performance Questionnaire (GLCCPQ) created from the works of Carmeli and Waldman (2010), Dobbins and Zaccaro (1986), and D. Miller (2003). Employees of businesses associated with a southeastern U.S. metro Chamber of Commerce accessed the online GLCCPQ and provided data reflecting an individual-level perception used to examine the four study hypotheses. Using correlation analysis for each hypothesis, the expected results confirmed a positive correlation existed between the two variables (cohesion and performance) in the forming, storming, and performing stages of a group’s life cycle. The strongest correlation occurred in the forming stage, contradicting Tuckman’s findings. The lack of correlation within the norming stage data set was unexpected. The study’s conclusions contribute to leadership effectiveness in the areas of influence, motivation, and organizational success. The findings extend the literature, offering an individual-level perspective examining the correlation between group cohesion and group performance at each stage of the group life cycle and not of the group as a whole. Finally, this research design and the GLCCPQ survey offer a strong foundation to spur future research and discovery on this topic.
