Q.Define Group and its characteristics.

Team Cohesion: The Glue That Holds a Team Together

Imagine a sports team where every player is individually brilliant — the fastest runner, the sharpest shooter, the most strategic captain. Yet they lose every match because they never pass the ball, never trust each other, and argue after every play. Now imagine a team of average players who move as one, cover for each other's weaknesses, and celebrate every small win together. They win. That invisible force that makes the second team greater than the sum of its parts is team cohesion.

At its simplest, team cohesion is the bond that pulls members toward the group and keeps them working together. It's the sense of "we" instead of "me." When cohesion is high, members feel a sense of belonging, are committed to the group's goals, and want to stay in the team. When it's low, people feel like isolated individuals who happen to share a workspace or a jersey.

The Precise Definition

In psychology and organisational behaviour, team cohesion is formally defined as:

The degree to which group members are attracted to the group and motivated to remain part of it.

This definition has two critical dimensions, first identified by researchers Festinger, Schachter, and Back (1950):

1. Task Cohesion — the shared commitment to the group's goals and objectives. It answers: Do we all want to achieve the same thing? A cricket team that all want to win the tournament has high task cohesion, even if they don't all like each other personally.

2. Social Cohesion — the interpersonal attraction among members. It answers: Do we like each other and enjoy being together? A group of friends who start a study group because they genuinely enjoy each other's company has high social cohesion.

What Makes Cohesion Happen?

Cohesion doesn't appear by magic. It grows from several factors:

• Shared goals — When everyone knows exactly what they're working toward, the group pulls together.
• Frequent interaction — Teams that meet, talk, and collaborate regularly build bonds.
• Group size — Smaller groups (5–12 members) tend to be more cohesive than large ones.
• External threats or competition — A common enemy or deadline can unite a team fast.
• Past success — Winning together creates a positive feedback loop: success builds cohesion, and cohesion builds more success.
• Homogeneity — Similar backgrounds, values, or interests make bonding easier (though diversity brings other strengths).

The Cohesion–Performance Loop

Here's the most important thing to remember: cohesion and performance feed each other. It's not a one-way street.

• High cohesion → better coordination, communication, and motivation → higher performance.
• High performance → pride, satisfaction, and shared celebration → even higher cohesion.

But there's a dark side. Too much cohesion can lead to groupthink — where members suppress disagreement to maintain harmony, leading to bad decisions. A cohesive team can also become hostile to outsiders or resistant to change.

How to Spot Cohesion in Real Life

You can observe cohesion through these signs:

• Members use "we" language ("We need to finish this," not "I need to finish this").
• They defend the group when outsiders criticise it.
• They show up on time and participate actively.
• They resolve conflicts constructively, not by avoiding them.
• New members are welcomed and integrated quickly.

One Exam-Ready Takeaway

If you're asked to define team cohesion in an exam, give the two-part definition: task cohesion (commitment to shared goals) and social cohesion (interpersonal attraction). Then mention that task cohesion is the stronger driver of performance. That's the core.
