• 1. What is the purpose (point) of doing

critique?

• To solicit feedback from peers, clients, bosses.
• To help designers broaden your communication skills.
• To have an opportunity for designers to explain not just

what you did but why you did it.

• 2. What is usability?

“The effectiveness, efficiency and satisfaction with which a specified set of users can achieve a specified set of tasks in a particular environment.” (by ISO)

• 3. List the 5 E’s one should consider when

doing evaluation.

• 5 E’s
• Effective: Can a user reach one’s goals?
• Find what they are looking for?
• Do what they want to do?
• Efficient: How fast to pursue the goals?
• Number of steps
• Engaging: Use it again? Recommend it to others?
• Number of revisits
• Error tolerant
• Number of errors
• Recovering from errors
• Easy to learn
• Amount of effort to learn

• 4. What is Cognitive Walkthrough? And

what are the three questions to ask?

A usability evaluation method in which one or more evaluators work through a series of tasks and ask a set of questions from the perspective of the user. The focus of the cognitive walkthrough is on understanding the system's learnability for new or infrequent users

1. Visibility: Is the control for the action visible to the user? 2. Affordance: Is there a strong link between the control and the action? (Will the user notice that the correct action is available?) 3. Feedback: Is feedback appropriate? (Will the user properly interpret the system response?)

• 5. Describe advantages and drawbacks of

heuristic evaluation.

Advantages

• It’s fast, quick and cheap to conduct a heuristic evaluation. This is

especially true if you are only going to use a single evaluator.

• It provides good insight into possible usability problems that

might damage the user experience.

Drawbacks

• A single evaluator may miss issues that are not readily apparent to
• them. The use of more than one evaluator is recommended.
• Heuristic analysis is subjective. It does not “prove” anything and

thus findings may be open to debate.

• Experienced evaluators are hard to come by and that means that

you may need to use less skilled evaluators whose findings may not be as valuable.

• 6. Why should you do pilot testing?
• To make sure everything is ready prior to conducting a usability

test

• The pilot test allows you to:
• Test the equipment
• Provides practice for the facilitator and note-takers
• Get a good sense whether your questions and scenarios are

clear to the participant

• Make any last minute adjustments

• 7. You are testing a new mobile application

for a pharmacy with users. Fill in the details for the following.

• Who will be test users? How many?

Ex: people who have prescriptions and need medicine

• What task you will give them? For how long?

Ex: Order/refill medication, Check prescription status

• What will be your evaluation criteria/strategy?

Ex: How effectively users can complete the task above?

• What kind of data will you collect?

Ex: Completion time, Number of errors , Qualitative user responses

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 1. Which design principle(s) among Norman’s 6 design

principles would you consider? Explain why.

Mention any one of “Visibility, Feedback, Affordance, Consistency, Mapping, Constraint” and explain why.

• Ex. “I’d consider affordance because the user should have a clue on

what controls to do what.

• Ex. “Mapping because people are used to thermostats being a certain
• way. It’s important to design with that in mind because…”

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 2. Who are the primary stakeholders?

Mention a particular kind(s) of users Ex: Home owners, landlords (no “users”, “designers”)

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 3. How would you collect data for user needs and

understanding task?

Mention specific data collection methods and/or what to ask Ex: “Survey the users about their day-to-day use of their thermostat. Collect data of when their thermostats are used and what they are set

• to. Interview them to gauge what they would want from the

device.” (No ”heuristic evaluation”!!!)

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 4. Give one concrete use case.

Describe how the system will be used in a certain case.

• Ex. “Bill goes to work every weekday from 9-5. The thermostat

recognizes this and turns off temperature control at 8, and back on at 4 so that the the room gets cozy.” (No to describing a goal/purpose of the system: Ex. “the user wants to decrease their utility bill and thus need to save energy”.)

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 5. Give one idea that utilizes your understanding of how

human memory works. Mention something related to “Recognition over Recall”

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 6. Which prototyping technique(s) would you use? Why?

Mention either one or more of sketches, low-fi, mid-fi, wire-frame, interactive prototypes, etc. with the reason.

• Ex. “Hi-fi prototype needs to be rolled out as fast as possible so that

the most accurate testing of a system can be done sooner.”

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 7. You are also designing a mobile app to control and monitor your
• thermostat. What kind of navigation would you use? Why?
• Ex. “I would use a up-down slider because people are used to that

format on normal thermostats. It is easy to figure out up is increase and down is decrease.“

• Ex. “I would put arrows on the screen to show how users can change

the temp and a screen that highlights outside temp so that people can adjust temp accordingly.”

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 8. Which of the 5 E’s would you weigh the most and the

second most for evaluation? Why?

Mention one of Efficiency, Effective, Error tolerant, Easy to learn, Engaging, and justify it.

• Ex. “Easy to learn and error tolerant because thermostats will affect

the living conditions of the user”

You are designing a new “smart” programmable thermostat that, in addition to what “normal” programmable thermostats do, also learns about usage patterns over time and optimizes its settings to provide better comfort and save energy.

• 9. How would you evaluate your product/prototype? Think

about experts/users and strategies.

Mention either one of expert-led studies (cognitive walkthrough or heuristic evaluation) or user studies with potential users and and describe describe further about it. further about it.

• Ex. “Evaluate through heuristics, testing how the users interact with

the system and how it can be improved for effectiveness.”
