From Clement Filippi presented at Amadeus (compilation of UX facts that improve quality of Design)
Basics
Ensure the design meets user and business needs • Purpose: Does the design fulfill the intended user and business objectives? • Standards: Is the design aligned with established UI standards (patterns, competitor, trends,…)? (linked to Consistency) • Research/data: Is the design backed by user research, data, and testing?
Structure
Optimize the organisation, flow, and access to the information
• Functional perimeter: Is the content relevant regarding the product goal? • Sitemap: Is the overall structure clear and logical? • User flow: Are the steps to complete tasks clear and logical? • Efficiency: Can users achieve their goals with minimal effort and confusion? • Progressive disclosure: Are complex features or information revealed only when needed? • Flexibility & personalization: Can users adapt the experience to their preferences when appropriate?
Visual Design
Optimize aesthetic appeal and usability through effective layout practices
• Minimalism: Does the design prioritize simplicity without sacrificing functionality? • Visual balance: Are elements weighted appropriately to avoid clutter? • Hierarchy: Is important content emphasized through size, color, or placement? • Alignment: Are elements visually aligned for a cohesive appearance? • Spacing: Does the layout include sufficient spacing for clarity (white space, margin, padding,…)? • Grouping: Are related elements visually and logically grouped? • Recognition over recall: Does the design minimize the cognitive load by presenting visible options and reminders? • Guidance & help: Are support mechanisms (tooltips, FAQs, autocomplete, error management…) integrated into the design when appropriate? • Transparency: Does the UI display the necessary information so that the user can make informed decisions without confusion (costs, fees, payment options, terms,…)? • Security & trust: Does the UI feel reliable to the user (trust symbols, privacy policy, …)?
Specifications
Address the real-world application of the design and its adaptability
• Error handling: Does the design anticipate user and system errors? • Use cases: Does the design support both minimum and maximum use scenarios? And what about responsiveness? • Realistic: Is it doable in terms of technological and business constraints? • Guidance & feedback: Does the design provide clear feedback on user actions?
Consistency
Ensure a predictable experience across the product
• Brand & design system: Are components Design Factory compliant? Does the design respect brand guidelines? • Visual consistency: Are design elements (colors, typography, spacing, …) used consistently? • Interaction patterns: Are product patterns consistently applied across similar functions? • Grid & layout standards: Is the design aligned with the established grid or layout framework?
Inclusivity
Ensure the product is usable by as many people as possible, regardless of ability
• Accessibility: WCAG AA Compliance (color contrast, keyboard navigation, and screen reader) • Localization: Does the design account for diverse user needs, such as different languages or cultural contexts?
Context
Design for growth and integration with the broader product ecosystem
• Adaptability: Can the design accommodate future features and functionality? • Ecosystem integration: Does the design fit into the broader ecosystem of related products or services?
