Reliability/Availability of Electrical & Mechanical Systems for C4ISR Facilities — TM 5-698-1

The purpose of this technical manual is to provide facility managers with the information and procedures necessary to baseline the reliability and availability of their facilities, identify "weak links, and to provide guidance toward cost-effective strategies of improving reliability and availability. The information in this manual reflects both the move to incorporate commercial practices and the lessons learned over many years of acquiring weapon systems. It specifically addresses electrical and mechanical systems for command, control, communications, computer, intelligence, surveillance and reconnaissance (C4ISR) facilities, focusing on the role reliability, availability, and maintainability (RAM) criteria play in supporting the mission. The manual, in the spirit of the new policies regarding acquisition and
evaluation, describes the objectives of a sound strategy and the tools available to meet these objectives.
