  1. Contextual Design

  2. Purpose for us • An example • A term often used, with varying levels of precision

  3. Purpose of CI • Translate ethnographic methods to more procedural methodology • A group can learn together • Structures group processes • Takes less time

  4. Focus on intentions • Intentions: purposes for accomplishing a task, apart from means • explicit or implicit • often a cascade of intentions • highest level change little over time • collection of lower-level = strategy for attaining higher level

  5. Contextual Design Steps • Contextual inquiry – field interviews and observations at work site • Work Modeling – captures the work of indidividuals and organizations • Consolidation brings data from individual customer interviews together so the team can see common pattern and structure without losing individual variation. • Work redesign – to improve work by using technology to help people do their work • Storyboards: how people will work with the new system • User environment design -- the ‘floor plan’ of the new system • Prototyping • Prioritization and object-oriented design

  6. Work Modeling captures the work of individuals and organizations • flow model: communication and coordination, • cultural model: culture and policy, • sequence model detailed steps to accomplish a task, • physical model: physical environment as it supports the work, • artifact model: how artifacts are used and structured in work.

  7. Consolidation brings data from individual customer interviews together so the team can see common pattern and structure without losing individual variation. • The affinity diagram brings together issues and insights across all customers into a wall-sized, hierarchical diagram to reveal the scope of the problem. • Consolidated work models bring together each different type of work model separately, to reveal common strategies and intents while retaining and organizing individual differences.
