Supervisors play a crucial role in executing tasks according to a manager's plan, ensuring processes and procedures are followed, and workers deliver results. In modern organizations, supervisors often act as team leaders, guiding empowered employees who have the freedom to adjust methods and technology. The TIPSI model, which stands for Trust, Instructions, Psychology, Support, and Improvement, is a new approach to supervision. It emphasizes building trust, following instructions, understanding the psychology of team members, providing support, and promoting continuous improvement.
