Satisfaction Questionnaire Results Company Logo
Analysis • Tabbing can help user to • Understand their position in the system • Decrease learning curve of the user • Tabbing can help usability design on • Help reduce steps of page to achieve our goals • Make our system more integrated • We infer this by comparing low and high fidelity measurement result Company Logo
Future Work • Implement the finance and meal modules • To test the system with a more diverse population. For example, to include more housewives Company Logo
Lessons Learned • The paper prototype was a useful tool to discover a good interface design taking little effort in its creation • The use of the usability heuristics and the scenarios help a lot to discover usability problems of an application • A navigation map helps to develop system with high-complex workflows Company Logo
Course Lesson Learn • Develop product concept • Understand context use of product • User behavior analysis that use the product • How to design interaction based on heuristic, product concept, context of use, and user behavior • Create prototype • Create specification as our target for usability • Evaluate our design to userbased on time, many errors, heuristic Company Logo
