Reflection
Due to constrained budget and time, the feature was designed through quick wireframing and prototyping rather than the conventional design thinking process. Usability evaluation was performed with other members of the company rather than with represented users. It would be more beneficial if the feature was tested with actual users to help identify potential usability problems and user experience with such feature.
