Organizational behaviour is a critical domain for Human Resource professionals in Kenya, as it directly influences how employees interact, collaborate, and achieve organizational goals. Managing groups and teams effectively is essential for fostering productivity, innovation, and employee satisfaction. This chapter focuses on understanding group dynamics within Kenyan workplaces, equipping HR practitioners with the knowledge to facilitate cohesive and high-performing teams across diverse sectors such as county governments, hospitals, universities, and financial institutions.

6.1 Group dynamics

Group dynamics are the forces that shape how people behave, interact and influence one another when they work together. These forces include shared rules, roles, relationships, communication habits and the use of power, and they decide whether a group produces good results or wastes its members' effort. Understanding them lets a supervisor or trainer predict problems early and guide the group towards its goal. Example: on a surgical ward at a county referral hospital, the nurses, clinical officers and ward attendants must hand over patients at shift change. The accuracy and speed of that handover depend less on individual skill than on how the group communicates, who is trusted and what the ward treats as normal behaviour.

6.1.1 Group norms

Group norms are the unwritten rules that tell members what behaviour is acceptable and what is not. They develop gradually through repeated interaction and are enforced by approval, teasing, silence or exclusion rather than by formal penalties. Norms can raise performance or lower it, depending on what the group has agreed to value. Example: a SACCO's loans committee may have an unspoken norm that every member reads the loan files before the meeting. A member who arrives unprepared quickly feels the group's disapproval and corrects the habit.

Common types of group norms

• Performance norms: these set how hard members work and how much output is expected. A group that expects completed tasks before leaving for the day will pull a slow member up to the same pace.
• Attendance and punctuality norms: these set whether meetings start on time and whether absence needs an explanation. Once lateness is tolerated, it spreads quickly.
• Communication norms: these decide who may speak, whether members interrupt, and whether disagreement is voiced openly or kept private.
• Dress and appearance norms: these set what members wear and how they present themselves. They often signal belonging to the group.
• Social norms: these cover shared tea breaks, greetings, celebrations and how members treat each other outside tasks. They strengthen relationships when they are positive.
• Confidentiality norms: these decide what stays within the group and what may be shared outside. They build the trust that open discussion needs.

6.1.2 Group roles

A role is the set of behaviours expected of a person because of their position or contribution in the group. Some roles are formal, such as chairperson or secretary, while others emerge naturally as members find what they do best. A group works well when the roles it needs are filled and members understand them. Example: in a hotel kitchen preparing for a wedding banquet, the head chef coordinates, the sous chef checks quality, and an experienced cook often becomes the person who calms others when orders pile up, even though that is not on any job description.

Task roles

Task roles move the group towards completing its work. They include the initiator who proposes ideas, the information seeker who asks for facts, the coordinator who links the contributions of different members, the evaluator who tests ideas against the goal, and the recorder who keeps notes of what was agreed.

Relationship roles

Relationship roles keep the group working together as people. They include the encourager who praises good work, the harmoniser who eases tension, the gatekeeper who invites quiet members to speak, and the compromiser who finds a middle position when views differ.

Self-centred roles

Self-centred roles serve the individual at the expense of the group. They include the dominator who controls discussion, the blocker who resists every proposal, the attention seeker who steers the conversation to personal achievements, and the withdrawer who contributes nothing. A group that does not manage these behaviours loses time and morale.

6.1.3 Group cohesion

Cohesion is the strength of the bond that keeps members attached to the group and willing to work for it. A cohesive group has members who value belonging, support one another and share its goals. Cohesion helps performance only when the group's goals match the organisation's goals. Example: a team of site workers at a building contractor who trust one another and aim to finish a school classroom block on schedule will cover for each other. If the same close group decides to slow down because it feels underpaid, its cohesion works against the project.

Factors that increase cohesion

• Shared goals: members who want the same outcome cooperate more readily and resolve disagreements faster.
• Small group size: in small groups every member knows the others well and feels responsible, so bonds form faster than in large groups.
• Frequent interaction: members who work and talk together regularly develop familiarity and trust.
• Success: a group that achieves results feels pride and wants to stay together to repeat the achievement.
• Common threat or competition: pressure from outside, such as a rival team or an approaching deadline, draws members closer.
• Similar background and interests: members who share values or experience find it easier to understand one another, although too much similarity can limit fresh ideas.

Factors that reduce cohesion

• Unequal participation: when a few members carry the work, resentment grows among those who contribute most.
• Disagreement on goals: members who pursue different aims pull the group apart.
• Large size: as numbers grow, members form sub-groups and individuals feel less connected.
• Poor experience in the group: repeated failure or unfair treatment makes members want to leave.
• Domination by a few: when one or two members control decisions, others stop engaging.

6.1.4 Communication patterns in groups

Communication patterns describe how information flows between members. The pattern a group uses affects speed, accuracy and member satisfaction, so a group should choose it to suit its task. Example: at a secondary school, the principal passing an instruction through the deputy to heads of department follows a chain, while a staff meeting to plan the term's calendar needs everyone to speak freely.

6.1.5 Status and power in groups

Status is the rank or prestige a group gives a member, while power is the ability to influence others' behaviour. Status can come from position, expertise, age, experience or personal qualities. Members with high status tend to speak more, are listened to more, and shape the group's norms. If status is not respected or is abused, resentment builds and communication suffers. Example: in a bank's credit department, a senior analyst with fifteen years of experience may carry more influence in a loan decision than a newly hired manager, because colleagues trust the analyst's judgement.

Sources of power in a group

• Legitimate power: this comes from a formal position, such as a chairperson or supervisor, and is accepted because of the role.
• Reward power: this comes from the ability to give benefits such as recognition, bonuses or favourable assignments.
• Coercive power: this comes from the ability to punish or withhold benefits, and it can create fear rather than commitment.
• Expert power: this comes from specialised knowledge or skill that the group needs.
• Referent power: this comes from being admired or liked, so that others follow the person's example willingly.

6.1.6 Negative group processes

Groups do not always perform better than individuals. Certain processes reduce the quality of decisions and the effort members give, and a trainer or supervisor should recognise them early. Example: a county office planning budget priorities may spend hours in agreement on a familiar road project and never examine cheaper alternatives, because no one wants to disturb the group.

Common negative processes

• Groupthink: members suppress doubts to keep agreement, so poor decisions pass unchallenged. It is most likely in cohesive groups with a strong leader.
• Social loafing: some members put in less effort because they believe others will cover for them and their own contribution will not be noticed. It increases as group size grows.
• Conformity pressure: members adopt the majority view even when they privately disagree, because they fear rejection.
• Group polarisation: after discussion, the group's decision becomes more extreme than the average of its members' views, either more cautious or more daring.
• Free riding: members enjoy the group's rewards without contributing, which discourages hardworking members.
• Sub-grouping and cliques: small circles form within the group and compete or exclude others, reducing cooperation across the whole group.
