In product interactivity, we use scenario to validate other models and understand dynamics b-what is there and what is wanted - implementation and deployment d- none of the above 2- Decoration, alignment, white space and grouping is a part of design process a- True False 3- Disadvantage of prototyping 2- Developers receive quantifiable user feedback b-Facilitates system implementation Potential future system enhancements None of the above 4- PC application widgets are like a- Radio buttons in physical devices b- External links - Site structure Controls buttons, lights...) 3- Local structure of a system is a- Showing what leads to what knowing where you are c-being task oriented d-Branching and looping 6- In starting with the design step in design process we focus on as ordering and understanding b- what is there and what is wanted lwhat to do and how to decide getting it right and finding what is really needed 7- In starting with the analysis step in design process we focus on - ordering and understanding b- what is there and what is wanted what to do and how to decide d-getting it right and finding what is really needed 8- Time spent on correcting errors is used as ISO 9241 metrics to measure the following a- the efficiency of suitability Bothe efficiency of the error tolerance c- the efficiency of the learnability d. The process of building a model of a user 9- In gathering the requirements, we focus on - Execution and evaluation b-Group related items together How is the prototyping d- What is wanted in a design 10- Percentage of functions learned is used to measure the b- the learnability efficiency the learnability effectiveness d- the Icarability suitability c- the leamability satisfaction 11- Advantage of prototyping b-Reduce development time a- Reduce development costs - Results in higher user satisfaction All of the above 2 4
