Which system does the Chairman of the Joint Chiefs of Staff (CJCS) use for joint strategic planning?

The Joint Strategic Planning System (JSPS) is the correct choice for the system utilized by the Chairman of the Joint Chiefs of Staff for joint strategic planning. This system is specifically designed to integrate various military and strategic planning processes, ensuring that strategic decision-making is comprehensive and coordinated across all branches of the U.S. Armed Forces. JSPS facilitates the alignment of military strategy with broader national security objectives, enabling effective resource allocation, operational planning, and readiness assessments.

In contrast, other options, while important in their own contexts, serve different purposes. The Joint Operations Planning System (JOPS) focuses on the execution of joint operations planning rather than broader strategic initiatives. The Defense Integrated Planning System (DIPS) is more oriented towards integrating defense planning processes but does not specifically cater to the strategic level of planning like JSPS. Finally, the Global Force Management System (GFMS) is primarily concerned with force allocation and management rather than the overarching strategic planning framework provided by the JSPS. Each of these systems has its own critical roles, but JSPS stands out as the designated system for joint strategic planning.
