Sample Maintenance Planning SummaryEngineering and logistics functional elements must coordinate and interfaceto maximize the usage of the data developed by each program element.Effective coordination can eliminate costly duplications of effort. Theprecursor to maintenance planning information is RAM data. The followingexcerpt from DoD 5000.2-R, paragraph 4.3.6, reveals this link, “Reliabilityrequirements shall address both mission reliability and logistic reliability.Maintainability requirements shall address servicing, preventive, andcorrective maintenance.”A maintenance planning summary may include supporting information fromthe RAM community that justifies the need for each maintenance action(e.g., failure modes, etc.). Other reliability and maintainability data thatcould also be incorporated includes, but is not limited to: task frequency,failure rate of an item or mean time between failure, mean time to repair anitem, mean time between maintenance actions, mean time betweenremovals, and operational availability (A o ).7.3.3 Repair AnalysisPurpose and ContentThese reports summarize the conclusions and recommendations of therepair level analysis.
