2. Final Project Determining musical preferences Ellen Kozlowski

3. GOMS Model Approximately 13-15 seconds for execution Dependent upon number of incorrect inputs entered Approximately 20 seconds to read and comprehend visual display Timed estimates correlated closely with GOMS model estimation

4. System Specification Use of generic user feedback of musical categories to provide song recommendation Input is based on musical category “rating” Recommendation is based on an attempt to accurately assess a user’s music preference Clear display of output is a focus of product

5. Design Considerations Feedback is quick and easy Calculations are clear-cut and logical Also, easily modifiable Recommendations are accurate within measurable standards Output is easily accessible and easy to understand

6. Quality Objectives Measures used: Reliability MTTF Maintainability Cyclomatic complexity Testability Measurable by planned vs. actual system testing Direct comparison

7. System Inputs 1-5 scale Criteria for each number varies for each music category Categories Bass Tempo Instrumentation Vocals
