1. Describe three interfaces you interact with on a daily basis.
2. Analyze each interface you identified in Question one and assess how it adheres to Mandel's five golden rules.
3. Suggest two changes for each interface to achieve a more user-friendly design and justify your suggestion.
4. Provide three screen shots for each interface.
Note:These screen shots should be labeled and appear in the appendix of the case study. These pages are not included in the page requirement for the assignment.
