Abstract:Where do differences originate in requirements users express for software? Research on sources of variance has largely ignored the effect of differences at individual levels and between organizations within one culture (Tsumaki & Tamai, 2006). A requirements study was conducted for a clinical trial management system being developed. Semi-structured in-depth interviews elicited 69 requirements in seven categories from 22 professionals (at three professional roles) at seven Dutch hospitals (four teaching and three district hospitals). Teaching hospitals expressed a broader scope of requirements. Professional roles did not systematically differ, suggesting a strong influence at task level (cf. Hori, Vicente, Shimizu, & Takami, 2001). Requirements are best elicited from the most experienced users at the organizations providing the broadest range of services.
