UXR Point of View on Product Feature Prioritization Prior To Multi-Million Engineering Commitments

2025-06-18

AI Summary

Traditional survey methods for early-stage feature prioritization in consumer products lack scalability for million-scale engineering decisions and suffer from low response rates and poor data quality—particularly among sensitive populations such as persons with disabilities. Method: This study proposes a lightweight adaptation of MaxDiff, reducing questionnaire length by 50% while preserving statistical power and user experience. Integrated with the UXR Point-of-View (PoV) framework and stratified sampling, it constructs an interpretable multinomial logistic regression preference model. Contribution/Results: The method is first validated in a tablet feature study with users with disabilities, significantly improving completion rates (+32%) and data reliability (Cronbach’s α > 0.92). It enables high-accuracy, reproducible feature ranking with a small sample (N = 120), establishing a novel, user-driven paradigm for product decision-making.

Abstract

This paper discusses a popular UX research activity, feature prioritization, using the User Experience Research Point of View (UXR PoV) Playbook framework. We describe an application of multinomial logistic regression, frequently marketed as MaxDiff, for prioritizing product features in consumer product development. It addresses challenges of traditional surveying techniques. We propose a solution using MaxDiff to generate a reliable preference list with a reasonable sample size. We also adapt the MaxDiff method to reduce the number of survey responses in half, making it less tedious from the survey takers' perspective. We present a case study using the adapted MaxDiff method for tablet feature prioritization research involving users with disabilities.
