PERSONALITY AND ITS EFFECT ON GROUP PERFORMANCE
In every organisation, people are the primary drivers of productivity, innovation, and competitive advantage, and how these people think, feel, and behave largely determines whether organisational goals are achieved. Beyond technical skills and formal qualifications, one of the most powerful forces shaping employee behaviour is personality. Personality influences how individuals approach work, interact with colleagues, respond to challenges, handle stress, and commit to organisational objectives (Woods & Anderson, 2024). As organisations operate in increasingly complex, competitive, and team-based environments, understanding personality has become essential for managing performance, fostering collaboration, and sustaining organisational effectiveness (McCrae & Costa, 2023).
PERSONALITY
Personality is commonly defined as the enduring pattern of thoughts, emotions, and behaviours that distinguishes one individual from another and shapes how people respond to their environment (Robbins & Judge, 2022). In a similar vein, McCrae and Costa (2023) describe personality as a stable system of psychological traits that influences how individuals perceive situations, regulate emotions, and behave across different life and work contexts. According to Goldberg and Saucier (2022), personality represents a structured configuration of dispositional characteristics that account for consistent patterns of behaviour, motivation, and interpersonal interaction over time. Likewise, Judge, Bono, and Locke (2023) conceptualise personality as the set of relatively permanent individual differences that determine how employees approach work tasks, relate with others, and react to organisational demands. In summary, although scholars differ in emphasis, they consistently agree that personality influences motivation, interpersonal relations, and work behaviour. This makes personality a fundamental factor in explaining variations in how employees contribute to organisational and group outcomes.
GROUP PERFORMANCE
Group performance on the other hand refers to the extent to which a team or work group successfully achieves its assigned goals through coordinated effort, effective communication, and efficient use of collective skills (Robbins & Judge, 2022). In a similar way, Salas, Reyes, and McDaniel (2022) define group performance as the quality and quantity of outputs produced by a group as a result of members’ ability to collaborate, share information, and integrate their individual contributions. According to Mathieu, Hollenbeck, van Knippenberg, and Ilgen (2023), group performance represents how well a team transforms the knowledge, skills, and abilities of its members into task accomplishment and goal attainment. From these definitions, group performance can be understood as more than the simple sum of individual efforts; it reflects how well members integrate their skills, communicate, and cooperate to achieve collective goals.
Personality plays a central role in shaping how individuals behave within groups and how effectively teams function. In the work context, groups are expected to coordinate diverse skills and personalities in order to meet organisational objectives. When personality traits within a team complement one another, groups are more likely to experience smoother interaction, stronger commitment, and higher levels of productivity (Woods & Anderson, 2024). For example, individuals high in openness to experience are more likely to contribute creative ideas and adapt to change, thereby enhancing group innovation, while conscientious individuals promote reliability, goal focus, and task discipline within teams (Barrick, Mount & Li, 2022). Extraverted members often facilitate communication and participation, agreeableness promotes harmony and trust, and emotional stability supports resilience and effective coping under pressure, all of which are essential for sustained group effectiveness (Salgado & Moscoso, 2024; McCrae & Costa, 2023). Conversely, poor personality fit can lead to conflict, miscommunication, and reduced performance. Thus, personality is not only an individual attribute but a powerful determinant of how well groups function and perform in organisational settings.
