Scenarios and testing

Seeking Concreteness Abstract Analysis Synthesis Concrete Framework Imperatives Analysis Synthesis Prototypes Observation Concrete

User visioning techniques Personas Storyboards Scenarios Video prototypes Use cases

Reasons to use them Build a shared understanding Get a comprehensive view Sell ideas Provide concrete examples for users Prioritize for implementation and testing

Scenarios at different levels General setting Day in the life Specific tasks (script)

Testing at different levels Paper prototypes Wireframes Screen mockups / clickthroughs (e.g., PowerPoint) Interaction prototype (e.g., Flash) System prototype

What to test – utility / usability Heuristic analysis Analytic modeling Open-ended demonstration/interview Structured (scripted) user test Naturalistic use
