Interaction Design
Work ModelsWork Models
• Work Models provide a way of capturing complex data
• Help the team see the work structure by representing it in physical diagrams– Flow Model– Sequence Model– Artefact Model– Cultural Model– Physical Model
Interaction Design
Flow ModelFlow Model
• Depicts Individuals, their working relationship, the information and artefacts which
support work.– Who is involved– Responsibilities– Groups– How they
communicate– Artefacts – Communication
topic– Places– Breakdowns
Interaction Design
SequenceSequence Model ModelComponents
Step: The thing the user did in an appropriate level of detail
Trigger: The situation that prompts a user to start a new task
Intent: The reason (known or unconscious) the user is doing the task or step

Interaction Design
Model ConsolidationModel Consolidation
• Build a single coherent view of the users’ work practice.
• Look for ways the system can be redefined– Defines system behaviour– Defines the way people do their jobs
• Reveal the structure of work across users.– Identify sequences that concern the same task– Identify common bottlenecks/breakdowns
Interaction Design
Ideas for redesignIdeas for redesign
• Can activity in sequence models be automated?• Can the intent be achieved in a more effective
way?• Are all current steps necessary?• Look at how role holders undertake the same
activities some may be more efficient• Eliminate all unnecessary steps and breakdowns• New designs should not create more work!
Interaction Design
Making use of contextual Making use of contextual AnalysisAnalysis
• Understanding of users and roles within the organization– Can be used to develop Personas
• Understanding the tasks and activities– Can be used to develop Scenarios
Interaction Design
PersonasPersonas
• Archetypes that are representative of actual user groups– Derived from contextual research– Description that includes behaviour patterns,
goals, attributes, skills etc.– By designing for these archetypes you may
satisfy a broader group of people.
• Should not based on real people
Interaction Design
Benefits of PersonasBenefits of Personas
• Allow for a greater understanding of users, their goals and activities.
• Provide a focus for the designer
• Act as a communication aid for the design team and their clients
• Can be used to evaluate features and functionality
• Can support other project aspects e.g selection of test users for evaluation studies
Interaction Design
Focused Data CollectionFocused Data Collection
• Pruitt and Grudin foundation document includes:– Demographics– A day in the life– Work activities– Household and Leisure activities– Goals, fears and aspirations– Skills, knowledge and abilities– Technology Attitudes– Communication

Interaction Design
Primary & Secondary PersonasPrimary & Secondary Personas
• Primary Personas– Those personas whose needs must be met.– Those whose needs cannot be met via an
interface designed for any other persona– Lowest common denominator for the design– One primary persona for each user group
Interaction Design
ScenariosScenarios
• Stories about what users do with the system– Includes agents (personas) who have goals or
objectives– Combine to perform a plot or of sequence of
events
• Usually written in the form of a narrative– Facilitates communication, understanding and
the relationship to the persona
Interaction Design
Benefits of ScenariosBenefits of Scenarios
• Provide a method for exploring all aspects of the interface
• An easy way of involving the user in the design process that they can understand
• They support other project aspects e.g. usability testing and documentation
Interaction Design
SummarySummary
• Contextual Design provides a structured method for gathering and analysing contextual data
• Method allows the researcher to move from an understanding of context to the envisionment of a new design
• Contextual data can be used to develop scenarios and personas which are useful during product implementation and evaluation
