IDI Leadership

Robert M. Liebe



Mr. Liebe has over twenty-two years of experience as a Marine officer, helicopter pilot, operations research analyst, and consultant. As a Marine helicopter pilot, Mr. Liebe achieved mission commander and instructor qualifications during a series of assignments as an operations officer, maintenance officer, and instructor pilot. As a Marine Corps analyst, Mr. Liebe has applied a wide array of analysis techniques to many different challenges. He developed a mixed integer optimization model to create 10-year aircrew training plans and facilitate resource investment decisions for the Marine Corps’ transition to tilt-rotor aircraft. Mr. Liebe applied Markov transition matrices to model military dental readiness and to help forecast wartime equipment attrition. Web-based survey, categorical data analysis, and structured interviewing techniques enabled Mr. Liebe’s analysis team to assess the comparative value of traditional and distance education programs for Marine officers. He deployed to Iraq with 3rd Marine Aircraft Wing in Spring 2003, where discrete event simulation and spreadsheet modeling assisted operational planning and subsequent operational assessment during Marine forces’ advance to Baghdad. Since joining IDI, Mr. Liebe has assisted in development of discrete event simulations supporting ship design decisions and case handling process improvement efforts at a large government organization.  He has also conducted research on risk analysis methods, techniques, and tools and their applicability to homeland security. He applied these analysis techniques and decision process design expertise in supporting Navy installation protection investment decisions, leading development of decision support models influencing $1B in annual resource allocation decisions.

Joseph A. Tatman

Vice President and Chief Technical Officer

Dr. Tatman has more than twenty-six years experience in the application, research and teaching of decision and risk analysis. He specializes in Bayesian networks in a broad array of applications including the analysis of complex political-economic-military problems, reliability analysis of complex systems, analysis of risk in system development, and development of interactive, online web analysis tools. He led the risk analysis and mitigation effort for a major government software system. He developed a comprehensive model for analysis of acquisition risk which was implemented in a multi-agency web application. Dr. Tatman led the user utility assessment of a prototype space sensor system, using an innovative structured process based on multi-attribute utility theory. He is one of the founders and the CTO of Innovative Decisions, Inc.
