When you’re working on a prototype, you’ll want to make sure that your design is well-executed and looks great on paper. However, you’ll also want to be sure that your design is feasible and can be implemented successfully.
One way to test the feasibility of your design is to comment on a prototype that a friend or colleague has created. InVision allows you to comment on any prototype, regardless of whether or not the prototype is publicly visible.
When commenting on a prototype, be sure to provide feedback about the design and how it could be improved. Additionally, be sure to note whether or not the prototype is feasible and whether or not you would be willing to help implement it.
Finally, be sure to provide a conclusion about your comments. This will help you to provide valuable feedback to your colleague or friend, and will also help you to better understand your own design preferences.
