In-depth interview provides valuable insights and if you plan to make a big change or a big investment, you should certainly not rely on statistical data and questionnaires. The interview will help you to get to know users’ views in more detail.
You will needpen and paper, dictation machine
Timeapproximately 60 minutes per user
Difficulty2 – it depends on researcher’s experience
- you want to find what the current needs and wishes of the users are
- you need to identify what the problem is and why
- you need to understand the findings obtained through quantitative methods of investigation (e.g. from Questionnaires)
Do not use when...
- you want to obtain a one-shot overview of your users’ opinions (we recommend to use questionnaire or a poll, instead)
- you need the user to come up with creative solutions to various problems during interviews (Focus Group method is better suited for this purpose)
- Prepare a script with a particular order of questions.
- Test the course of an interview with a colleague.
- Think about the manner of recording the interview and prepare the equipment. Choose a nice place, select the participants and invite them to the place.
- The initial questions should break the ice. Continue with questions about users’ behavior and experience and finish with questions on users’ opinions, knowledge, and emotions. You do not have to strictly follow the script.
- As the informal farewell can provide you with the most valuable information, take your time with concluding the interview.
- Transcribe the interview and mark the important parts. Look for recurring themes.
- When finished with the interviews, summarize new information about the interviewed users. Use your results to create personas or when empathy mapping.
Keep in mind that...
- processing and analyses of in-depth interviews might be time-consuming, but worth the results
- you need to stay focused throughout the whole interview and show interest in what respondent says; watch out for body language
- develop respondent’s answers with follow-up questions, simply go in depth
