Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

29. They only involve the elements that you have written on the cards - They suggest solutions that imply structure - They become difficult to navigate with more categories






30. Location - Logical Grouping - Conventions - Redundancy






31. What it will look like - What components it will require - How the screens will be laid out






32. They can be used early and often - They are inexpensive and easy to create - They make design idea visual - No special knowledge is required - all team members can create them






33. They can be difficult to create f the target audience is international - Having too many personas will make the work difficult - There is a risk of incorporating unsupported designer assumption

35. 1.They facilitate the development of design procedures 2.They help in finding ways to talk about design 3.They create project management






36. Easy and inexpensive to make - Flexible enough to be constantly changed and rearranged - Complete enough to yield useful feedback about specific design questions






37. Intention formation - specification of the action - and the execution stages are complex - Require a rather accurate mental model of the computer's internal processing
