To be considered
• What tools to choose for the prototyping and development phases
• Can work done/implementation from the prototyping stage be reused?
Example: Online store
• Holvi, free + 3%/transaction• Shopify, 29$/month + 3-5%/transaction• Woocommerce, 100-1000€/year sw + 5-30€/month
hosting + 2%/transaction• Tailor made: 30’000-100’000 development + 100€/month
hosting + 2%/transaction
SW testing outcomes
User testing = Implementation quality• Usability• UI design• Speed• Can be done in lab
Concept validation =Solution quality• Right problem?• Good solution?• Interaction with context• Only works in the field
The two outcomes of prototyping
Planned outcomes• Evaluation results
Unplanned outcomes• Serendipity• Require listening• Open mind
Risk = f(uncertainty)
Time

Reducing risk = reducing uncertainty
Decision
Why must I validate the design?
• Identified and interpreted the users needs correctly• Concepts fit the users (not the designers)• Both qualitative and quantitative data can be gathered
Validation is ...
• Two way communication between design team and user • Medium for this communication the prototypes
(artifacts).• Detail and quality improved the further the development
process goes • All the different levels are used all the time
Current design =hypothesis
Select most criticalassumptions
Invent ways to testthe assumptions
Define success criteria for tests
Discover underlyingassumptions
Assumption = something that must be true in
order for the design to be valid
Implement test(s)
Execute test(s)
Evaluate test results
Decision:go, no go, redesign
New design
Do’s
• Test in real context• Use humans for complex “behind the scene tasks”
– Concierge services, Wizard of Oz• Less is more, seek minimum useful functionality
Don’t
• Waste time on overhead functions– Login, user profile, etc
• Over-rely on A/B testing– Good for incremental improvement
