The budy system is a procedure in which two people, the buddies, operate together as a single unit so that they are able to monitor and help each other. In adventurous or dangerous activities, where the buddies are often equals, the main benefit of the system is improved safety: each may be able to prevent the other becoming a casualty or rescue the other in a crisis. When this system is used as part of training or the induction of newcomers to an organisation, the less experienced buddy learns more quickly from close and frequent contact with the experienced buddy than when operating alone. This concept is also applicable to minimise tool setup time.
