... Third, we will study the technological level of current reliability, availability, and maintainability practices as a foundation for recommendations about the potential applicability of recently developed reliability, availability, and maintainability methodology, or the need for new statistical developments. The next section reviews reliability, availability, and maintainability testing and evaluation in the military services.
From page 29...
... In the Army, reliability, availability, and maintainability data for a system are scored by a joint committee involving personnel from the Operational Evaluation Command, the Army Materiel Systems Analysis Activity, the Training and Doctrine Command system manager, and the program manager. In the Air Force, reliability, availability, and maintainability evaluation is part of the mission of the Logistics Studies and Analysis Team within the Air Force Operational Test and Evaluation Center's Directorate of Systems Analysis.
From page 30...
... (The Training and Doctrine Analysis Command is another example of a group for whom an upgrading of capabilities in statistical modeling and analysis could pay some big dividends.) In its review of Air Force Operational Test and Evaluation Center procedures and practices, the panel was impressed by the care with which materials for training suitability analysts were assembled, and with the coordinated way in which reliability, availability, and maintainability procedures were carried out on specific testing projects.
From page 31...
... Such efforts complement attempts to standardize practices across the services and encourage the use of best current practices. The panel does believe that reliability, availability, and maintainability "certification" can better be accomplished through combined use of data collected during training exercises, developmental testing, component testing, bench testing, and operational testing, along with historical data on systems with similar suitability characteristics.
From page 32...
... The agenda for the next phase of the panel's reliability, availability, and maintainability-related work will include, as high priorities, increased contact with the Air Force and Marine Corps and assessment of the quality and appropriateness of current reliability, availability, and maintainability practices, together with the formulation of possible amendments aimed at greater precision, efficiency, and protection against risk. We will undertake two main activities: identifying relevant materials related to the identified case studies: interacting with Navv Onerational Test and Evaluation Force staff to increase our familiarity ~ -C7 , ~ ~ with their procedures and with the Army Materiel Systems Analysis Activity to better understand their role in Army reliability, availability, and maintainability methodology for developmental testing.
