RE’03: PRACTICAL REQUIREMENTS ENGINEERING SOLUTIONS Ongoing Requirements Discovery in High-Integrity Systems

Ongoing Requirements Discovery in High-Integrity Systems by Robyn R. Lutz and Inés Carmen Mikulski, pp. 19–25. The discovery of new requirements and new requirements knowledge continues throughout the lifetime of many high-integrity embedded systems. Anomaly reports from testing and operations on eight spacecraft at the Jet Propulsion Laboratory revealed four mechanisms for how we discover and resolve requirements. Understanding these mechanisms identifies guidelines to help prevent anomalies found during testing from recurring during operations.
