    The Selected Essential-item Stock to Availability Method (SESAME) is the approved Army tool for implementing the least cost mix of spare parts and repair parts in order to achieve Availability goals. The Level of Repair Analysis (LORA) is the approved Army tool used to determine where an item should be replaced, repaired, or discarded based on Cost and Operational Readiness requirements. Is there an equivalent approved Army tool for MAC development? Believe LSA formerly served that purpose but LSA is no more. If there is no tool, is there an approved Army specification or standard that defines MAC development?


    Yes. The US Army Materiel Command (AMC) Logistics Support Activity (LOGSA) developed and maintains the "PowerLOG-J" software tool to develop, evaluate, review and integrate product support data for materiel systems, to include the development of the Maintenance Allocation Chart (MAC).

    PowerLOG-J satisfies requirements for information and product support data transfer in accordance with Government Electronics and Information Technology Association (GEIA) Standard 0007, Logistics Product Data. PowerLOG-J directly supports the conduct of Task Analysis (Activity 12) as required by MIL-Handbook-502A Product Support Analysis paragraph 5.5.2 through its generation of over 50 product support summaries and reports, to include Task Analysis, Maintenance Allocation Chart, Provisioning Technical Documentation, Bill of Materials, Failure Modes Effects and Criticality Analysis, and the Repair Parts and Special Tools Lists (RPSTL).

    US Army LOGSA provides PowerLOG-J at no cost to all Government personnel and contractors, and hosts a PowerLOG-J Users Group. Users can download PowerLOG-J software and register in the Users Group thru the PowerLOG-J website
