Group Dynamics and Decision Making in the Workplace

Introduction

In the modern vocational environment, relatively few enterprises consist of sole individuals; even small businesses involve groups of people who must work together collaboratively. Group dynamics apply to all working groups and, depending on how well various elements of positive group dynamics manifest themselves operationally, they have the potential to greatly enhance or to substantially undermine the group's objectives. In general, a group provides a much wider range of specific talents, abilities, and capabilities toward the accomplishment of objectives. However, the relative effectiveness of groups depends largely on variables particular to group dynamics. Various theories of group dynamics, decision making, and motivational patterns outline the interrelationships of group members and describe methods of facilitating positive relations that are conducive to achieving group objectives. Competition in the workplace represents a potential source of positive motivation but also a potential obstacle to group performance, depending on the nature and source of that competition.

In many respects, the elements of group dynamics are functions of deeply ingrained features of individual psychology, such as the concepts of individual needs first described by Maslow and the susceptibility of individuals to groupthink. In other respects, the elements of group dynamics pertain more to leadership styles and strategies of conflict recognition, prevention, and resolution by management.

Specifically, Adair's Three Circles concept describes effective leadership from the perspective of the group; Blanchard and Hersey detailed the various management roles of directing, coaching, supporting, and delegating responsibilities; and Tuckman outlined the five stages of group evolution — forming, storming, norming, performing, and adjourning. In the field of human motivation, McGregor postulated the Theory X/Theory Y formulation, and Herzberg contributed the Hygiene Theory of human motivation to complement the basic individual psychological concepts detailed by Maslow.

Group Dynamics and Individual Decision Making

In the 1950s, Solomon Asch and others designed social psychology experiments that demonstrated the tremendous influence that groups have on individual decision making and judgment (Gerrig & Zimbardo, 2005; Locker, 2003). These experiments also illustrated the degree to which biological arousal attributable to the presence of others changes the way individuals perform — increasing performance in areas of high skill while decreasing performance in less skilled individuals in ways not normally perceived by the individual (Myers & Spencer, 2004).

Generally, Asch's experiments consisted of situations in which subjects were placed into groups of experimental cohorts for the purpose of examining the degree to which group opinions influenced individual perception and subjective judgment. Asch purposely used subject matter whose correct analysis was not particularly challenging, such as lines of different lengths depicted in a visual field in which their relative lengths were rather easily distinguishable under ordinary circumstances without external influences (Gerrig & Zimbardo, 2005). In approximately one-third of experimental cases, subjects ignored their own accurate perceptions and supported the group consensus even though they knew the group was wrong. That effect was most pronounced where no other group member expressed a differing opinion, but was also apparent anytime the perceptions of the minority conflicted with those of the majority (Aronson, Wilson, & Akert, 2003).

The implications of these observations in the business environment include the tendency of groups to make poor decisions by virtue of groupthink, even where individual group members disagree with those decisions. In such situations, individuals either suspend their objective judgment or refrain from voicing their concerns — even when they recognize that the group is wrong — because of perceived pressure to conform to the group consensus or reluctance to suffer the social consequences of contradicting the direction in which the group has already indicated its preference (Locker, 2003).

Maslow's hierarchy of human needs originally described the fundamental psychological needs of the individual, consisting of (1) basic physiological needs, (2) immediate physical security needs, (3) social needs, (4) self-respect, and (5) self-actualization (Blair, 2003; Gerrig & Zimbardo, 2005). In principle, Maslow's hierarchy of human needs is equally applicable to group behavior, except that the first two levels — basic survival and physical security — are normally not applicable to most vocational environments.

More particularly, business managers must understand the degree to which individual employee performance, and therefore group performance as well, depends on fulfillment of the same social needs, desire for self-respect and appreciation, and vocational achievement or advancement that correspond closely to the last three stages of Maslow's five hierarchical levels (Blair, 2003).

The implications of applying Maslow's hierarchy in the vocational setting include specific management efforts to motivate superior performance by refraining from policies, practices, and procedures that unnecessarily detract from individual employee self-respect. Likewise, good industrial psychology practices suggest that providing fair opportunities for recognition, increased responsibility, and career advancement based on performance are essential to maintaining optimal employee performance (Blair, 2003; Myers & Spencer, 2004).

Theories, Concepts, and Practical Applications of Group Dynamics

In the 1960s, Ken Blanchard and Paul Hersey introduced the concept of situational leadership, in which they broke down effective group leadership into four specific tasks: (1) directing, (2) coaching, (3) supporting, and (4) delegating (Blair, 2003; Myers & Spencer, 2004). According to Blanchard and Hersey, leaders vary in the relative proportion their styles emphasize among these four functions, but they tend to fall into one dominant style or another.

The directing function encompasses defining the respective roles of individual group members, supervising their performance, and communicating managerial decisions to the group. Coaching emphasizes communication with individual group members and often includes a two-way exchange to a greater degree than the directing style. The supporting function allocates operational decisions to group members, in which the leader plays only a contributing role. The delegating function provides the greatest degree of control and decision-making authority to group members, including determining the extent to which and manner in which the leader participates in operational decisions (Blair, 2003).

Subsequently, Blanchard and Hersey expanded their theory of situational leadership to make it more applicable to specific situations by incorporating the talents, abilities, and skill levels of individual group members (Blair, 2003). The variables they identified consist of four different levels of competence and commitment, ranging from high competence and high commitment — characterized by extreme technical competence, confidence, and very high motivation — at one extreme, to low competence and low commitment — characterized by an absence of technical competence and very low levels of confidence, motivation, and commitment — at the other (Blair, 2003).

The practical implication of Blanchard and Hersey's situational leadership concept is that effective group performance depends substantially on the degree to which group leaders tailor their leadership styles to the needs of the group. In particular, optimal group performance requires group leaders to understand the varying capabilities and attitudes of individual group members. This allows leaders to apply different communication, supervision, and motivation strategies that correspond to the varying needs of different groups and to the different needs of individuals within those groups.

Shortly after the prior work of Blanchard and Hersey, British psychologist John Adair introduced the concept of the three most basic needs of collaborative groups, which he represented in three partially overlapping Venn diagram circles labeled "task," "team," and "individual" (Blair, 2003). Adair described task needs as those related to the operational objectives of the group; team needs primarily in terms of interpersonal interaction and communication within the group; and individual needs as the varying personal needs of each group member. Adair emphasized the importance of managerial attention to all three types of needs for the purpose of maximizing group productivity. Adair's formulation is now considered extremely basic to industrial psychology; nevertheless, the concepts of task, team, and individual needs effectively describe the range of considerations fundamental to contemporary theories of group dynamics (Blair, 2003).

Roughly between the respective contributions of Blanchard and Hersey and Adair, Bruce Tuckman introduced the theory of four stages of group evolution, which he subsequently augmented in 1977 to include a fifth stage suggested by Mary Ann Jensen.

Conclusion

The theories examined in this paper collectively demonstrate that effective group performance depends on a nuanced understanding of both individual psychology and group-level dynamics. Asch's experiments reveal the powerful influence of social conformity; Maslow, McGregor, and Herzberg together illuminate how individual needs and motivational factors drive performance; and Blanchard and Hersey, Adair, and Tuckman provide actionable frameworks for understanding leadership roles and group development. Managers who apply these frameworks are better equipped to foster motivation, resolve conflict, and guide groups toward their objectives.
