This is a guide to running a good user interview. It follows on from our article about why you should do user interviews as part of your user research. It explains how to prepare for an interview and the types of questions to ask.
User interviews require good preparation. If you don’t prepare then you won’t find out what you need. It would be like looking for treasure without a map, a compass, a spade or a good pair of boots.
It takes effort to prepare but it means you won’t be digging up a load of unhelpful sand or data.
First up, this means acknowledging there are things you don’t know. It’s OK to not know them, or to have assumptions (we all have them).
“Just acknowledging that there are things you don’t know you don’t know puts you in a much stronger position vis-a-vis reality.” Erika Hall, Design Researcher
Then work out what you need to know. We call these research questions. They are different to the questions you will ask in the interview. They are more about documenting what learning you need to move forward with the problem you are trying to solve. Erika Hall writes beautifully about the need to dig in the right spot. If you don’t work out where to dig, you’re unlikely to find treasure.
Bad research question: How do we get people to use our service?
Good research question: How do people go about seeking help?
Good interview questions: How do you manage the problem? Can you tell me about the process you went through when deciding to contact the service?
Use this worksheet to get started.
This is like finding the right island to go treasure seeking on.
Who are your users or potential users? Can you describe them? Be specific then seek them out. You only need five to start with!
You might find them among your existing cohorts of service users. Or you may need to go further and enlist support from other organisations.
Work out the most direct route to reaching them. Directness is important. The more people you have to go through to reach them, the longer it will take and the less responses you will get.
Write something clear and compelling about who you are looking for, why and what you need. Ideally put this on the web: on a page, or an online form. Then ask people to visit it or show it to potential interviewees.
Always ask for consent. Adapt your normal consent form into an online form using a survey tool. You can also ask a consent question at the start of an interview if you are recording it.
This is a bit like getting your digging boots on or your spade out of the shed.
Whether it’s your first or fiftieth user interview, it always helps to have a script. A script ensures you cover off all the things you need to explain at interview start. It also helps you start the interview with more confidence. You don’t need to follow a script word for word but you do need it written down and in front of you when you start an interview.
Your script should include:
Every question should be...
Talk normally. This isn’t a survey. People talk more when a conversation feels natural.
Sometimes you might get stuck or want to know more. When you need a prompt:
Prioritise
Before the interview, work out your most important questions. They may not be the first you ask, but you need to know them. Then, if an interview doesn’t go to plan, you can skip the other questions and ask your most important ones before you run out of time.
Behaviour is more reliable than predictions or views and opinions.
“Ask people what they did, to share their experiences and behaviours, not describe what they do or want to do.” - Dan Sutch, CAST
Don’t ask about future behaviour. We are bad at predicting it. Asking about it will get you a hypothetical answer. It’s risky to make decisions based on these.
So, avoid hypothetical questions like ‘would you use x…?’. Instead ask practical questions about things like:
Giving timeframes will make it much easier for the interviewee to answer, like ‘in the last six months, how often have you used x?’.
Include tech or service habits
Knowing what technology your users are using is crucial to building any new product or service. It can also help debunk some of those long-held internal assumptions about your users.
Ask about their good and bad experiences. Listen to how they felt, what they saw, what they did, what they used, how they experienced it.
This will help you understand:
Remember to look beyond their experience of your service. You’re here to learn about their broader experiences of the problem, how they cope and how they behave.
“A good question is 'Tell me, when you did X or when X happened to you, what went through your head?'. Then people tend to describe their feelings and thoughts in a natural way that is really valuable to you.” - Ab Brightman, Catalyst
Views and opinions aren’t so useful. They tend to be based on people’s ideas, thoughts and beliefs. It’s more useful to try to understand their motivations, the root causes of their experiences and their expectations of your service and the world.
To find these out you need to ask ‘why?’. When you receive a view or opinion either enquire why, or move on to a more practical question.
This advice applies particularly to asking people what they want. Don’t just ask people what they want. Instead ask why they want it. That has much more value.
“There are some scenarios where I find asking 'what do you imagine X will be like?' can be handy for drawing out expectations. So you're not asking what they want, or for them to predict their behaviour but instead to paint you an image. E.g. asking 'what do you imagine would happen if you went to the sexual health clinic?' could reveal that they've been avoiding it because they think there will be a difficult conversation around being gay.” - Ab Brightman
Shifting to user interviews and the curiosity mindset that goes with them is a process not an event. We’re here to help you make the shift. Use a Design Hop to get started, or even a Digital Candle call for some 1-1 support.
