The United States Department of Defense (DoD) engages in complex decision making on a daily basis, in terms of mission support and workforce management. Decision analysis tools are employed to evaluate and support the best course of action. In particular, multi-objective decision making (MODA) is a robust decision technique that evaluates objectives and measures in terms of value to select from a set of alternatives. This paper examines workforce planning at a DoD Agency through the use of MODA and examines the ratio of government employees (GOV) and contractors (CON) for an engineering related work role. MODA is used to identify influences to the assignment of a GOV or CON to an open position and to determine the appropriate ratio of GOV and CON employees for the work role. Results will be used to provide critical decision support to effectively manage budget and resources while meeting work requirements and agency mission with the best possible skill set
