This document discusses groups and team building. It defines a group as a collection of individuals that come together to achieve a common objective. There are two main types of groups: formal groups, which are deliberately created by management and have defined roles and tasks, and informal groups, which form naturally due to common interests. Examples of formal groups include command groups, task forces, and committees. Informal groups include friendship groups and interest groups. Team building refers to activities that motivate team members and improve a team's overall performance by increasing cooperation. The goals of team building include developing clear objectives, improving processes, identifying strengths and weaknesses, and enhancing communication and problem solving skills.
