What is one major advantage of building a paper prototype?

Building a paper prototype offers the significant advantage of encouraging honest feedback. This approach allows users to interact with a tangible representation of the design without the distractions or complexities introduced by high-fidelity digital prototypes. Participants often feel more at ease providing open and candid feedback on a paper prototype, as it presents a low-stakes environment where the focus is more on the usability and flow of the design rather than on its visual polish or technology.

Furthermore, since the prototype is simple and quick to create, users can concentrate more on how the design meets their needs and less on its current visual aesthetics. This openness can lead to more valuable insights that can significantly improve the design before moving to more expensive or resource-intensive stages of development.
