Groups are an essential feature of organisational life. A group can be defined as two or more individuals who interact and work together to achieve a purpose. Groups may be formally created by management or may form informally through social interaction. There are several reasons why groups form in organisations.
The first reason istask and goal achievement. Formal groups are created to achieve organisational objectives that require collaboration. For example, in procurement, a cross-functional sourcing group may be formed to run a tender process involving operations, finance, and procurement staff. Individuals form these groups because working together helps them achieve outcomes that they could not accomplish alone.
The second reason issocial and psychological needs. According to Maslow’s hierarchy of needs, people seek belonging and relationships. Informal groups often form to meet these needs, providing friendship, support, and a sense of identity. In Star Fish Ltd, for instance, employees working remotely may form a social group using Teams or WhatsApp to stay connected and reduce feelings of isolation.
The third reason issafety and security. Groups can give members confidence and protection when facing uncertainty or change. For example, during organisational restructuring, employees may form informal groups to share information and support each other, making them feel less vulnerable. In procurement, staff may collaborate in groups to manage supplier risks or market volatility.
The fourth reason ispower and influence. Groups provide individuals with a stronger collective voice. Trade unions are a formal example, but informal groups can also lobby management or resist unpopular changes. In procurement, buyers might form a group to influence senior managers on issues such as introducing sustainable sourcing practices. By forming groups, individuals can increase their bargaining power and impact decisions.
In conclusion, groups form for task achievement, to satisfy social needs, to provide security, and to increase power and influence. Managers must understand these dynamics because groups can both support organisational objectives and create challenges if informal groups resist change. Effective leaders harness the benefits of group formation while addressing the risks to ensure both cohesion and productivity.
