Team building is the process of turning a group of individuals into a cohesive team, a group of people organized to work together interdependently and cooperatively to meet the needs of their customers by accomplishing a purpose and goals.
Team building can include the daily interaction that employees engage in when working together to carry out the requirements of their jobs. It can also involve structured activities and exercises that either employees lead or they contract out for facilitation with an external resource.
When using an external facilitator for team building, groups can participate in structured activities that are designed to help the employees coalesce into an effective team. Generally, the facilitator works with a group of employees to design the team building activities or sessions. These can include ice breakers, discussion topics, games, cooperative assignments, and group brainstorming.
