Prototyping Affects Everyone
Role Unintended Effect Adjustment
Designers• Added stress of hitting tight
deadline • Highlighted need to iterate
Smarter planning in future phases/projects
Clients • Can’t react quickly enough • Want to “shop it around”
• Repeated expectation setting
• May still need deliverables
Project managers• Increases clarity on what
will be built • New work to manage
Discussion needed to get comfortable with new process
(at a minimum)
Developers & testers
