Bill Dalton

Partner

In his over 35 year consulting career, Bill Dalton has led many consulting assignments for public and private sector clients in the aerospace, automotive, civil construction, electric power (nuclear and fossil fuel), financial services, transportation, shipping and shipbuilding sectors. These assignments have generally involved analysis, decision frameworks and advice to improve management of complex development programs and to structure policy and strategy initiatives. Most assignments included using advanced dynamic simulation methods.

Bill holds an M.S. in Ocean Systems Management from MIT and a B.S. in Ocean Engineering from MIT.

Tamara Greenlaw

Director

Tamara has over 12 years of experience utilizing causal modeling and analysis methods to help address a range of complex security issues including shaping for strategic access, radicalization and violent extremist organizations, organized crime, and humanitarian assistance, as well as high stakes management issues such as capability prioritization and cross functional readiness drivers.

Tamara leads Sage's efforts to adapt and tailor causal methods including: structuring disciplined, transparent causal analysis efforts in environments with sparse information and many sources of uncertainty; aligning causal methods with military Design, Planning, and Assessment practices; tailoring causal methods given demanding end user planning and adaptation contexts; and exploring potential hybrid System Dynamics / machine learning methods. She has worked with OSD P&R, OPNAV N81, N3-5, Marine Corps PA&E, Army PA&E, several US Combatant Commands, Joint Staff J8, Joint Staff J5, DARPA, ONR, and ASD R&E.

Tamara holds a B.S. in Engineering from the University of Maine and MBA and M.S. Engineering degrees from MIT.

John Lyneis

Director

John is an expert in the use of dynamic simulation models to advise senior clients on complex strategy, policy, and program challenges. John has developed original simulation and conceptual models to help prioritize actions, understand the implications of major investment decisions, improve performance, evaluate growth strategies, and manage risk. John’s work typically involves highly calibrated and tailored system dynamics models grounded in quantitative data and / or qualitative causal analysis.

John has been the technical lead on a broad range of assignments over 15+ years. These include program modeling for several major DoD acquisition programs, analysis of infrastructure and platform sustainment challenges in energy and aerospace & defense, cross-functional capability prioritization to support military readiness, and personnel and workforce modeling.

John holds a Ph.D. in System Dynamics from the MIT Sloan School of Management and a B.A. in Political Science from Yale University.

VADM (Retired) Rick Snyder
