Which scenario best matches the UCD definition?
Usability testing with users is conducted only once the product is ready for launch.
Users are involved at all stages to prioritise their needs and context
Designers rely on market research reports instead of direct user involvement.
Users are consulted mainly after the prototype stage
Put these **UCD stages** in the most logical order:
Launch → Research → Iterative Design → Implementation → Concept
Research → Concept → Iterative Design → Implementation → Launch
Concept → Research → Implementation → Iterative Design → Launch
Research → Implementation → Concept → Iterative Design → Launch
A key **advantage** of multidisciplinary UCD teams is that they:
Eliminate the need for user research
Guarantee zero design trade-offs
Surface diverse perspectives for more creative, user-grounded solutions
Reduce time to launch to market

Time consuming
Conflicting priorities that must be resolved
Costly
Hard to create well rounded and intuitive products

Breaking down user activities to reveal pain points and critical steps
Comparing competitor feature lists
Choosing manufacturing processes
Which set correctly lists usability objectives ?
Accessibility, legibility, novelty, delight, trust
