Scenarios of use support the integration of cognitive and organization
al approaches to human-computer interaction (HCI) by providing a rich

cenario-based analysis and design-one focused on causal relationships
implicit in episodes of individual problem-solving and learning-is ext
ended by emphasizing an organizational work view of social causes and
effects.
