I would highly recommend taking DAUs Life Cycle Sustainment Plan (LCSP) continuous learning class:  CLL005 Developing a LCSP.

While not technically a part of the LCSP  the Depot Maintenance Support Plan (DMSP) should be referenced (not duplicated) in the LCSP.  The DMSP should be a consideration that is documented in the LCSP and how it impacts the other logistics aspects detailed in the LSCP. Other Resources: DAU LOG Blog post at https://www.dau.mil/training/career-development/logistics/blog/Everything-You-Need-to-Know-About-the-Life-Cycle-Sustainment-Plan-(LCSP), which contains links to a half dozen related resources, references and training opportunities
