The point where you challenge your ideas and create opportunitites to make them better!
It is a powerful stage to revisit and reassess your ideas.
You might then get feedback on how:
the end users feel with the outcome - Attitudinal
the end user uses or wants to use - Behavoural
Innovation vs Optimisation
are you discovering a whole new way for something to be done - Innovative
are you using existing experiences to up the performance - optimisation
Feedback
You should have already worked through this process earlier.
Using the same FEEDBACK MATRIX from above get further feedback on your refined ideas.
This feedback should make putting together your Final Design quiet easy.
Remember:
Feedback should be helpful
Help with choosing options / give direction
Might identify a gap or something that hasn't been considered
Make sure it feedback given is constructive and relevant
You are trying to get rid of the unintended consequences.
If feedback is unconstructive it can be ill-aimed, irrelevant, antagonistic.
