The management of customers' QoS requirements has its own unique set of issues to be addressed. These are best identified and focused by decoupling management issues from other viewpoints of QoS. The chapter offers guidelines to address these issues. The approach may appear rigorous but there is no substitute for the 'fire-brigade' approach of remedying faults as and when they occur. Such an approach should be resorted to only for dealing with unanticipated problems and emergencies and should not be used as a substitute for professional management of determining and studying customer's QoS requirements.
