Assignment #3 Preview — User Interview

Available now (so you can preview and prep), but can wait until Wed

You will interview a user from outside this room. Extra points will be given if you interview users who are not like you. For example, to improve Canvas:

  • Pitt students (also use Canvas)
  • CMU instructors (not me to avoid cognitive bias)
  • CMU non-STEM students
  • CMU administrators
  • CMU graduates
  • Student from other schools who use different products

After assignment #3, we will pool everybody’s data to begin synthesis.

HOMEWORK

7 of 18

If the past lectures have prompted you to rethink your original problem statement or scope, that is OK. Simply include your revisions as you submit assignment #3.

HOMEWORK

We will now watch an interview video together.

Try to identify one thing the interviewer did well, and one thing that the interview could have done better (e.g., “could have asked a follow up question on…”)

Post to #lecture:

Did well:

Could do better:

A recap on Interview Tips

Interview questions: Goods and bads

Get specific

Tasks, roles, and details of tasks

Ask for examples & demonstration like an apprentice!

Open ended

be ready to hear something new and be changed by it

Semi-structured

Have an agenda – Interviewer needs data about specific kind of work

Steer conversation to stay on useful topics

But respect triggers and unexpected new topics

Common pitfalls

Suggesting answers

Hypothetical questions

12 of 18

Interview questions: Goods and bads

Several types of questions, to help you brainstorm

Behavioral: Can you describe a recent occasion when a patient alert was sounded, and tell me what you did?

Feeling: What do you like most about your job?

Knowledge: If a patient says she is in pain, what do you look for?

Illustrative questions: Some nurses hate working at night, but others like the flexibility. What’s your experience?

Role-playing questions: If I were a new nurse coming to this hospital, and I asked you what I should do to succeed, what would you tell me?

Preparatory questions: We’ve been talking about your job. Now I want to ask you about how you got to be where you are today.

13 of 18

Listening, drilling down, and follow up questions

Validate & rephrase

Share interpretations to check your reasoning, clarify terms

Ex. “So accountability means a paper trail?”

Repeat/rephrase/summarize to make sure you understood

People will be uncomfortable until the phrasing is right

Keep it concrete when people start abstracting

People summarize, but we need details

Watch for words “generally”, “we usually”

“We usually get reports by email”, ask “Can I see one?”

Ask why

Ask for an example

Ask for step-by-step actions

14 of 18

Additional interview activities

Role-playing

For the rest of the class

  • We’ll separate into groups of 2-3 people.
  • Identify if any of your partners are target users of your product. If so, use one of them as the interviewee.
  • Separate in such a way that person A is the user, person B is the interviewer, and person C is observing the interviewer’s technique.
  • After the first interview, we’ll rotate. Each interview will be given ~15 minutes.
  • For the purpose of our class session, we won’t spend extreme amounts of time with introductions or thank yous.
  • Make an introduction, then ask the user to perform tasks related to your assignment #1 problem statement. If they finish quickly, then it is a good sign that your statement may be too narrow. Ask them to perform additional tasks.
  • Record your performance (conduct on zoom). You’ll want to use this data.
  • Time permitting, the observer will share feedback and pointers.
