Coping with Uncertainty in UX Design Practice: Practitioner Strategies and Judgment

2025-04-30

AI Summary

This study addresses the underexplored, context-dependent nature of uncertainty in UX design practice—arising from shifting stakeholder priorities, resource constraints, and team collaboration tensions—where existing research lacks deep contextual analysis. Employing a qualitative methodology combining multi-week reflective diaries and in-depth interviews, we conducted an empirical investigation with 10 practicing UX designers. We systematically identify and name two novel forms of design judgment: *temporal judgment* and *sacrificial judgment*, revealing uncertainty as an inherent, situationally embedded characteristic of UX work. Further, we distill three core adaptive strategies—adaptive reconfiguration, negotiated progression, and judgment anchoring—and establish design judgment as the central cognitive capacity for navigating uncertainty. These findings advance UX methodology toward an uncertainty-sensitive paradigm, reframing uncertainty not as a barrier but as a constitutive feature of design practice.

Abstract

The complexity of UX design practice extends beyond ill-structured design problems to include uncertainties shaped by shifting stakeholder priorities, team dynamics, limited resources, and implementation constraints. While prior research in related fields has addressed uncertainty in design more broadly, the specific character of uncertainty in UX practice remains underexplored. This study examines how UX practitioners experience and respond to uncertainty in real-world projects, drawing on a multi-week diary study and follow-up interviews with ten designers. We identify a range of practitioner strategies-including adaptive framing, negotiation, and judgment-that allow designers to move forward amid ambiguity. Our findings highlight the central role of design judgment in navigating uncertainty, including emergent forms such as temporal and sacrificial judgment, and extend prior understandings by showing how UX practitioners engage uncertainty as a persistent, situated feature of practice.

Problem

• Examining UX practitioners' strategies to handle uncertainty in projects
• Exploring the understudied nature of uncertainty in UX design practice
• Identifying design judgment's role in managing persistent situational uncertainty

Innovation

• Multi-week diary study with follow-up interviews
