Use cases & scenarios

Compromises

  • Focusing on wrong metrics leads to misleading optimizations.
  • Over-simplification can remove important functionality.
  • Ignoring technical constraints creates implementation issues.
  • Test with real users, not only internal stakeholders.
  • Combine quantitative and qualitative data.
  • Document design decisions and make them repeatable.

I/O & resources

  • User research (interviews, tests, analytics)
  • Business goals and product metrics
  • Technical constraints and design system
  • Validated prototypes and wireframes
  • Usability reports and prioritized actions
  • Measurement plans and dashboards for UX KPIs

Description

UX Best Practice consolidates established design principles, methods, and evaluation techniques for creating user-centered products. It helps teams improve usability, accessibility, and efficiency by providing decision rules and measurable criteria. It includes research methods, prototyping, usability testing, and metrics for outcome assessment.

✔

  • Higher user satisfaction and lower drop-off rates.
  • Clearer prioritization of product decisions.
  • Early identification of accessibility issues.

✖

  • Requires access to representative users for valid results.
  • Requires investment in research and prototyping.
  • Not all findings can be directly scaled.

  • Task success rate

    Share of users who complete a defined task successfully.

  • Time on task

    Average time users take to complete a task.

  • System Usability Scale (SUS)

    Standardized questionnaire to measure perceived usability.

E-commerce checkout redesign

Redesign reduced drop-off by simplifying steps and clarifying error communication.

Mobile onboarding optimization

Iterative testing and personalized content significantly increased activation rates.

Dashboard accessibility

Adjustments to contrast and keyboard navigation improved usability for a sizable number of users.

⚠️ Technical debt & bottlenecks

  • Outdated components causing UX inconsistencies.
  • Missing telemetry for tracking UX KPIs.
  • No documented design system, leading to high maintenance effort.
Lack of user dataMissing research capacityTechnical constraints of UI platform
  • Conducting usability tests with inappropriate target groups.
  • Measuring metrics without context or objectives.
  • Checking accessibility superficially instead of implementing it holistically.
  • Wrong generalization from small samples.
  • Over-reliance on benchmarks instead of user feedback.
  • Omitting technical feasibility checks before broad rollout.
