The interview is a fundamental quality tool, but frankly one we spend little time talking about best practices. The Quality Toolbox, by Nancy Tague, only dedicates about a page to this, for example.
Here is a proposed best practice, called cognitive interviewing.
PLANNING THE INTERVIEW
Plan the interview in advance by jotting down what answers you need and what questions you’ll need to ask to get them. Ensure that interviews are done timely – recollections degrade over time and conflations may occur.
APPROACHING THE INTERVIEW
It’s important to approach the interview in a way that the individual is willing to talk to you and share information openly and in detail. If you make the interviewee defensive, answers to your questions will be short and reluctantly provided. Here are some basic strategies to make the interviewee more likely to speak openly and honestly:

APPROACHING THE INTERVIEW
It’s important to approach the interview in a way that the individual is willing to talk to you and share information openly and in detail. If you make the interviewee defensive, answers to your questions will be short and reluctantly provided. Here are some basic strategies to make the interviewee more likely to speak openly and honestly:
- Ask for the interview at a time and place that’s convenient and comfortable for the interviewee
- Focus on finding root cause, which requires teamwork – the interviewee is part of the Investigation Team

Use open- and closed-ended questions together – open-ended to probe deeply, and closed-ended to confirm what you heard. Consider the following features of an effective interview:
- Mental Reinstatement: Encourage the interviewee to mentally recreate the environment and people involved. Encourage recreating elements such as where things were, temperature, lighting, and feelings. Holding the interview at the gemba further reinforces recall.
- In-Depth Reporting: Encourage the reporting of all details. This ensures the interviewee’s perception of what is relevant does not come into play – they may leave out details they think unimportant.
- Multiple Perspectives: Ask the interviewee to recall the event from others’ points of view. How would it have appeared to other people present at the time?
- Several Orders: Ask the interviewee to recount the timeline in different ways, like stepping backwards through the event. New perspectives might trigger recall of more information.
