Relevant Items MaxDiff: its Origin, Motivation, and Options

Описание: Relevant Items MaxDiff was introduced as a cutting-edge method by Chris Chapman and Eric Bahna at the 2018 Sawtooth Research Conference. Relevant Items MaxDiff is an adaptive MaxDiff methodology that tailors the set of items shown to each respondent, displaying only those that are deemed “relevant” to the respondent based on prior screening. Relevant Items MaxDiff was released in Sawtooth's Lighthouse Studio in 2020 and it was recently included in Sawtooth's Discover in May 2025.

In this presentation, Chris discusses the importance and use cases for Relevant Items MaxDiff, including its applications and considerations for designing a survey. He presents empirical data from a case study at Google, and discusses crucial analysis options. Bring your questions to this presentation, which is guaranteed to inspire you to conduct new varieties of MaxDiff surveys!
