What is MaxDiff Analysis? Complete Guide

MaxDiff (best-worst scaling) helps quantify relative preference across many attributes without scale bias.

When to use MaxDiff

Use MaxDiff for feature prioritization, message testing, value proposition ranking, and portfolio decisions where “everything is important” in rating scales.

Design principles

Keep lists concise, balance item exposure, randomize blocks, and ensure clear mutually exclusive statements. Include quality checks for speeders and straightliners.

Interpreting outputs

Interpret utility scores relatively, then segment by role, market, or region. Look for both global rank and segment divergence to inform roadmap trade-offs.

Common mistakes

Avoid overly technical item wording, too many near-duplicate attributes, and underpowered sample sizes for segment analysis.
