- Early paper prototyping is a good way to figure usability, efficiency and learnability issues.
- Observation of user behaviours that we could not have predicted ourselves.
- Because paper prototyping is quick and easy, it allows to iterate through many different design options. Paper prototyping particularly helped us to find the most intuitive location for buttons and navigation controls; find out safety issues (e.g. confirming that tweets are being saved); because the paper prototype was to scale we got a good indication if the layout works well.
- The drawback of a paper prototype was that it did not allow us to foresee many implementation challenges, accurately test typography, colour schemes.Observation of user behaviours that we could not have predicted ourselves.
