A _____ is a requirement or condition that a system must satisfy or an outcome that a system must achieve.

A requirement or condition that a system must satisfy or an outcome that a system must achieve is best described as a requirement. This is a fundamental concept in systems analysis and design, as it defines what the system is expected to do and the conditions under which it operates.

Requirements are essential to the development process because they serve as a foundation for system design, development, and testing. They provide clear guidelines for stakeholders, including developers, clients, and users, ensuring that everyone has a unified understanding of what needs to be delivered.

While specifications detail how these requirements will be met, constraints refer to limitations or restrictions within which the system must operate, and a goal typically represents a desired outcome or vision rather than a concrete condition to be fulfilled. Therefore, the term that accurately captures the essence of a requirement or condition that a system must meet is best described as a requirement.
