Process
Sequential mixed methods research in 3 steps
Interviews to find the questions, a survey to size the answers

The most common way to combine qualitative and quantitative research. Start with 8 to 12 interviews to learn the problem space, use what you hear to write a survey for 200 to 500 people that shows which themes are widespread, then go back to a few respondents to explain anything surprising. It stops teams from writing a survey before they know what to ask. Koji can run both the interviews and structured rating questions in one study.

What's in this process
- Qualitative first: Interview 8 to 12 participants to understand the problem space and find the questions that matter.
- Quantitative second: Turn what you learned into a survey for 200 to 500 participants to see which themes are widespread.
- Qualitative follow-up (optional): Interview a subset of survey respondents to dig into the results that surprised you.
