Unit 3: Group Dynamics and Team Development

I. Orientation: The Group as a Social Unit

Organisational work is rarely solitary; people combine into groups whose behaviour differs from the sum of individual behaviours. This unit studies how such collectives form, mature, perform and evolve into teams. The foundational figure is Kurt Lewin, who coined "group dynamics" (c. 1944) and framed group behaviour as a field of interacting forces.

• Group (defining features): Two or more people who interact, are interdependent and share a common goal or identity, e.g. a five-member audit team reviewing one client.
• Interdependence: Members' outcomes depend on one another, so behaviour is shaped by the presence of others (social facilitation, conformity).
• Norms: Shared, often unwritten standards governing conduct, such as an accepted response time to a colleague's email.
• Roles: Expected behaviour patterns tied to a position, e.g. task-leader versus record-keeper.
• Cohesion: The degree of mutual attraction binding members and their willingness to stay.
• Structure: Status hierarchy, size and communication channels that stabilise interaction.

These properties recur in every section below.

II. Group Dynamics and Its Significance

A. Meaning

Group dynamics denotes the forces and processes operating within a group that influence its members and its outputs.

• Lewin's field view: Behaviour is a function of the person and environment, B = f(P, E), so the group climate itself changes what members do.
• Two senses: (1) the study of group processes as a discipline; (2) the actual internal forces (attraction, pressure, influence) at play.

B. Significance

Group dynamics matters because most organisational value is produced collectively, and the group either amplifies or drains individual effort.

• Productivity leverage: A cohesive group aligned with organisational goals raises output; the Hawthorne studies (1924–32) showed informal group norms controlled worker output more than pay.
• Behaviour regulation: Norms enforce discipline and quality without formal supervision, e.g. peer pressure curbing absenteeism.
• Support and satisfaction: Belonging meets social needs, reducing stress and turnover.
• Decision quality: Pooled information improves choices, though risks like groupthink can distort them.
• Change management: Lewin found it easier to change people in groups than individually, because the group re-sets the norm.

III. Types of Groups

A. Definition and Basis

Groups are classified chiefly by whether the organisation creates them formally or they arise spontaneously.

1. Formal groups: Created by the organisation's structure to accomplish specified tasks.
   • Command group: Defined by the reporting hierarchy, e.g. a manager and direct reports.
   • Task group: Members drawn across lines to complete a specific job, e.g. a product-launch group; may dissolve on completion.
2. Informal groups: Arise from social needs, not managerial design.
   • Interest group: Members unite around a shared objective, e.g. staff lobbying for flexible hours.
   • Friendship group: Bonds from common attributes such as age, hobby or region.

B. Other Distinctions

• Primary vs secondary: Primary groups involve close, personal, enduring ties (family, tight work crew); secondary groups are larger and impersonal (a department).
• Membership vs reference: A membership group is one you belong to; a reference group is one whose standards you adopt as a benchmark, even without belonging.
• In-group vs out-group: The "us" a member identifies with versus the "them" seen as outsiders, shaping loyalty and bias.

IV. Formation and Stages of Group Development

A. Why Groups Form

People join groups to satisfy needs that individual effort cannot.

• Security: Strength in numbers reduces felt vulnerability.
• Status and esteem: Membership confers recognition.
• Affiliation: Meets the human need for social contact.
• Power and goal achievement: Collective action accomplishes what one person cannot, e.g. a union.

B. Formation and Stages of Group Development

Tuckman's model (1965) describes five sequential stages through which most groups mature.

1. Forming: Members meet, test boundaries and depend on the leader for direction; behaviour is polite and uncertain.
2. Storming: Conflict emerges over roles, control and approach, e.g. two members contesting who leads; the highest-tension stage.
3. Norming: Cohesion develops, norms and roles settle, and members accept shared expectations.
4. Performing: Energy focuses on the task; the group functions autonomously and productively.
5. Adjourning (added 1977): A temporary group disbands after completing its task, often with a sense of loss.

• Non-linearity: Groups may regress, e.g. a new member pushing a performing group back to storming.
• Punctuated-equilibrium alternative: For deadline-driven task groups, Gersick found long inertia broken by a burst of change at the temporal midpoint rather than smooth stage progression.

V. Group Performance Factors

A. Determinants of How Well a Group Performs

Group output depends on structural, compositional and process variables that either add to or subtract from members' combined potential.

• Size: Smaller groups act faster; larger ones gather more input but invite social loafing, the tendency to exert less effort when effort is pooled (Ringelmann effect).
• Composition: Diversity of skills aids complex tasks but can slow cohesion; homogeneity speeds agreement.
• Roles: Clear role allocation prevents ambiguity and conflict; role overload lowers performance.
• Norms: Performance-supporting norms lift output; restrictive norms cap it.
• Status: Perceived rank affects who speaks; high-status members can dominate and suppress useful dissent.
• Cohesion: Boosts performance only when group goals align with organisational goals; high cohesion plus low alignment can institutionalise low output.
• Leadership: Direction, coordination and motivation quality set the ceiling on results.

B. Group Effectiveness Equation

Actual performance is potential productivity minus process losses.

Actual Productivity = Potential Productivity − Process Losses

• Potential productivity: Best possible output given member resources and task demands.

• Process losses: Coordination failures and motivation losses such as social loafing.

• Worked example: Three workers each move 100 boxes/hour alone (potential 300). Working jointly they move 240; the 60-box shortfall is the process loss from poor coordination and loafing.

VI. Team Development

A. Team: Purpose and Principle

A team is a special, high-performing group whose members share collective accountability and complementary skills for a common purpose. Team development is the deliberate process of turning a set of individuals into such a unit.

B. Team Formation

Team formation is the structured effort to assemble and align members so the whole exceeds the sum of parts.

• Goal clarity: A shared, measurable purpose, e.g. cut defect rate by 10% this quarter.
• Complementary skills: Deliberate mix of technical, problem-solving and interpersonal abilities.
• Mutual accountability: Members hold one another responsible, not just the leader.
• Small size: Typically under a dozen, to sustain interaction and shared responsibility.
• Team-building activities: Goal-setting, role clarification and trust exercises accelerate the norming-to-performing shift.

C. Its Types

Teams are classified by purpose, membership and mode of interaction.

1. Problem-solving team: Members from one area meet to suggest improvements, e.g. a quality circle; usually advisory only.
2. Self-managed team: Takes on supervisory duties like scheduling and task allocation, operating with little external control.
3. Cross-functional team: Members from different departments at a similar level combine to coordinate a complex project, e.g. engineering, marketing and finance on a new product.
4. Virtual team: Geographically dispersed members collaborate through technology; gains reach but loses non-verbal cues and immediacy.

VII. Difference Between Group and Team

A. The Core Distinction

Every team is a group, but not every group is a team; the difference lies in accountability, synergy and purpose.

• Goal: A group shares information to help each member perform within their own responsibility; a team pursues a single collective goal.
• Accountability: A group is individually accountable; a team adds mutual, joint accountability.
• Synergy: Group performance is roughly the sum of individual contributions (neutral or negative synergy); a team generates positive synergy where the whole exceeds the parts.
• Skills: Group skills are random or varied; team skills are chosen to be complementary.
• Leadership: A group often has one clear leader; a team frequently shares leadership roles.
• Work product: A group produces individual outputs; a team produces a collective work product.

B. Illustration

• Group case: Ten sales representatives reporting to one manager, each hitting personal targets and sharing tips at meetings, yet judged individually.

• Team case: A five-person cross-functional unit jointly owning a product launch, where failure by one is failure by all and success is shared.

• Managerial implication: Converting a working group into a team requires investing in shared goals, mutual accountability and complementary staffing; without positive synergy the extra coordination cost is not justified, and a well-run group may be the better structure.
