Functional Requirements
Functional requirements are the specific capabilities, behaviors, and features that a space or astronautical system must possess to meet the needs of its users and stakeholders. These requirements are typically derived from the mission objectives and are used to guide the design, development, and testing of the system. Functional requirements can include a wide range of specifications, such as performance criteria, operational constraints, safety requirements, and environmental considerations. They are often expressed in terms of quantitative metrics, such as speed, accuracy, reliability, and efficiency, and must be validated through rigorous testing and evaluation. The process of defining and managing functional requirements is critical to ensuring that a space or astronautical system meets its intended purpose and delivers value to its users and stakeholders.
