Abstract

Needs analysis is a prerequisite to effective design, but typically is difficult and time consuming. We applied and extended our methods and tools in a case study helping a mission control group for the International Space Station. This domain illustrates the challenges of information-system domains that lack rigid, immutable, physical constraints and boundaries. We report the successes & challenges of our approach and characterize the situations where it should prove useful.
