Rank the five usability criteria (Shneiderman's usability measures) below in terms of relative importance, where 1 being the most important, and 5 being the least important. It is important that you must not have any ties; this must be a total ordering.
|Time to learn:|
|Speed of performance:|
|Avoiding user errors:|
|Retention over time:|
Specify what you think the goal should be for the five usability criteria, and what the actual system achieved. Use a time measurement (seconds or minutes) for the time to learn. For the speed of UI performance, use the number of interactions needed to accomplish the task (e.g., 2 mouse clicks to delete a selected email). Use the scale low, moderate, high, and very high, in terms of how important the avoiding user errors criterion is. This scale also applies to the retention over time and subjective satisfaction criteria.
|Criterion||Goal (should be)||Actual (achieved)|
|Time to learn|
|Speed of UI performance|
|Importance: Goal||Importance: Actual|
|Avoiding user errors|
|Retention over time|
The following questions are designed to establish a thoughtful evaluation of a user interface. Answer the questions on a scale of 1 to 5, where 1 is a strong no, 5 is a strong yes, and 3 is neutral. If the question does not apply, mark "N/A". Support your answers in your written report. In particular, any questions that get a "1" or a "5" should be discussed explicitly in your writeup. You can answer questions 13 - 15 in the space provided or in your writeup.
|1||Is the terminology consistent?|
|2||Is the terminology appropriate?|
|3||Is the terminology in the user's vocabulary?|
|4||Are the instructions consistent?|
|5||Do the instructions accurately describe the task?|
|6||Are the colors appropriate?|
|7||Do the display layouts simplify the tasks?|
|8||Is the sequence of displays appropriate?|
|9||Is it easy to customize the interface?|
|10||Are the error messages helpful?|
|11||Is it easy to correct errors?|
|12||Is the online help consistent and useful?|
|13||Include any additional criteria or questions you feel should be addressed.
