This report provides initial analyses on seven core themes of interest to the Personnel Studies and Oversight Office (PSO) from the Marine Corps Organizational Culture Research (MCOCR) Project. This exploratory research was requested by Manpower and Reserve Affairs and conducted by the Translational Research Group (TRG) at Marine Corps University's Center for Advanced Operational Culture Learning. Based on initial questions from Marine Corps leaders, this report is problem-focused. The focus should not be taken as an indication that Marines spoke exclusively about the negative aspects of their time in the Marine Corps. In fact, it would have been just as feasible to produce a report focused on positive experiences and perspectives. The project yielded several thousand pages of transcripts that can be mined for insights on a broad range of topics over time. This report is the primary deliverable for the first phase of the MCOCR Project and was produced quickly to support PSO. Analyses on additional topics will be conducted during the second phase of the project. Prioritization of topics and work schedule are being developed to balance additional MCOCR work with TRGs other responsibilities.
