The point where two or more separate areas of responsibility (or scopes of work) meet;
Where information regarding work processes, work scopes, technical requirements or personnel responsibilities etc, is exchanged to ensure compatibility and consistency;
The connection between two teams, contracts, functions, or pieces of equipment.
