Focus on intentions

• Intentions purposes for accomplishing a task,
  apart from means

• often a cascade of intentions
• highest level change little over time
• collection of lower-level strategy for
  attaining higher level

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

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.

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.
