Step 1: Recall the concept.
Co-ordination is often called the essence of management because it binds all managerial functions together into a unified whole.
Step 2: Identify Feature 1 - Integration of Group Efforts.
Co-ordination integrates the efforts of individuals and different departments. It channels diverse and unrelated activities into a purposeful, goal-directed effort, ensuring that performance matches the planned schedule.
Step 3: Identify Feature 2 - Ensures Unity of Action.
The core aim of co-ordination is to secure unity of action among all groups within the organization. It acts as a binding force, aligning every team toward a single common purpose so that no effort is wasted or duplicated.
Step 4: Identify Feature 3 - Continuous Process.
Co-ordination is not a one-time activity that a manager performs and then forgets. It is a continuous, ongoing process that begins at the planning stage itself and continues through organizing, directing, and all the way to controlling.
Step 5: Connect features to the broader role of management.
These three features together show that co-ordination is not a separate function but an inherent quality woven into every managerial act, keeping the organizational machinery running smoothly.
Step 6: Conclude.
The three features of co-ordination are: (1) Integration of group efforts, (2) Ensures unity of action, and (3) Continuous process.
\[ \boxed{ \text{Features of Co-ordination: Integrates group efforts, Ensures unity of action, Continuous process} } \]
