Which of the following is a description of a mission by the identification of the organizational entitlements and resources needed to perform the mission?

The correct answer is the Program Element Code (PEC), which serves as a critical identifier for categorizing and managing resources within a specific mission framework. The PEC is utilized in the planning, programming, budgeting, and execution of resources necessary for various missions. It encapsulates the entitlement and resource requirements affiliated with a mission, effectively tying together the elements necessary for command and control.

The PEC helps in ensuring that all organizational entitlements—such as personnel, equipment, and funding—are properly aligned and identified for mission execution. It allows for clear tracking and management of resources dedicated to particular projects or missions within an organization. By providing this systematic approach, it aids in maximizing resource efficiency and efficacy.

Other options, while related to mission planning and resource allocation, do not specifically focus on the identification of organizational entitlements like the PEC does. The Mission Resource Plan outlines the resources required for conducting a mission but doesn’t serve as a defined code for tracking resource allotment. The Operational Capability Statement describes capabilities needed but isn't focused on individual entitlements. The Entitlement Resource Analysis is an evaluative tool, rather than a systematic identifier like the PEC.
