Such groups may be either permanent in the form of top management team such as board of directors or management committees, work units in the various departments of the organisation, staff groups providing specialised services to the organisation, and so on; or the formal groups may be constituted on temporary basis for fulfilling certain specified objectives. When such objectives are fulfilled they disappear. These may be in the form of temporary committee, task force, etc. The working of formal groups is regulated by organisational rules and regulations.

Purpose—Since formal groups are deliberate creation, they are created for achieving the legitimate objectives of the organisation.
