(For example, if the 4X4 option is chosen the requirement to have a stronger frame is required and added.).Ī Requirement may be “Functional” or “Non-Functional”. Indirect Requirements are derived from other requirements or specifications. Stakeholder Requirements may come from internal or external end-users of the manufactured item (For example, an airline may have a requirement that the aircraft shall be able to fly 4,000 NM at cruise speed.). Regulatory Requirements usually come from sites like the Federal Aviation Agency(FAA) or Department of Transportation(DoT) (For example, DoT requires that all seats in an automobile shall have a seatbelt.). Requirements usually come from 3 sources: Government (or regulatory), Stakeholders and Indirect (“INPUTS” shown above). Requirements are one of the base pillars of the MBSE (Model Based Systems Engineering) design methodology. Written, verbal or implied, requirements give us the baseline to know when our designs are complete or ready to release/manufacture.
Requirements are the specifications that we design to. Quality Design Methodology: Implementing Traceable Requirements to drive a robust and efficient design process.
