Abstract :
Describes the resource allocation and planning helper (RALPH) scheduling system developed at NASA´s Jet Propulsion Laboratory. RALPH addresses the concerns of designing software systems to minimize the need to recode for changes and upgrades; this concern is acute when requirements are uncertain or changing. Determining requirements, understanding the problem, designing for change, and tradeoffs are also discussed.<>
