The Defense Integrated Military Human Resources System was an enterprise program of the Business Transformation Agency's Defense Business Systems Acquisition Executive, within the United States Department of Defense (DoD). As the largest enterprise resource planning program ever implemented for human resources, DIMHRS (pronounced dime-ers) was to subsume or replace over 90 legacy systems. The first phase of DIMHRS was expected to roll out first to the U.S. Army in 2009 and bring all payroll and personnel functions for the Army into one integrated web-based system. The U.S. Air Force, United States Navy and the Marines were expected to roll out in that order after the Army had implemented it. On January 16, 2009, the Deputy Secretary of Defense issued a memorandum directing the Military Departments (MILDEPS) and the Defense Finance Accounting Service (DFAS), to confirm the "core" enterprise requirements of the capability at that time. Once, confirmed, the BTA was to transition the solution to the individual MILDEPS to build out and deploy their own required personnel and pay solutions using the "core" to the maximum extent possible..(Memorandum, Deputy Secretary of Defense, January 16, 2009, Subject: Acquisition Decision Memorandum for the Defense Integrated Military Human Resources System). The solution was transitioned to the MILDEPS on September 30, 2009. After numerous delays, technical problems, and other issues, in February 2010, the DoD completed the transition of the program, after 11 years and $850 million.
