The process of translating user requirements into technological specifications using mathematical models is described using the example of mission requirements for designing the next generation environmental satellites. The analysis provides an end‐to‐end traceability from the user mission figures of merit to the software algorithm and hardware sensor design specifications. The models employ a wide range of error budget mathematical analysis tools that are easily executed using a spreadsheet program on a desktop computer. The analysis also shows that the infrared sensor in the existing satellites does not meet the user needs for identifying thin cirrus clouds and that the proposed sensor for the next generation satellites will easily meet the proposed performance user requirement. © 1999 John Wiley & Sons, Inc.
