Usability has become an integral part of every application design & usage, especially those related to the UI look & feel. Be it web or mobile, end users like user friendly & intuitive applications. An IT enterprise needs to focus on usability to save development costs and increase sales.

Usability is defined by five quality components (all defined from users’ standpoints) :

  • Learnability: How easy is it to accomplish the basic tasks the first time they encounter a design?
  • Efficiency: Once they have learnt a design, how quickly can they perform tasks?
  • Memorability: When they return to the design (after a period of not using it), how easily can they re-establish proficiency?
  • Errors: How many errors do users make, how severe are these errors, and how easily can they recover from them?
  • Satisfaction: How pleasant is it to use the design?

To ensure & measure Usability and UI specifications of a solution across the multiple browsers and devices, LTI shares & tests high-level designs and UI mock-ups with stakeholders and users to ensure & measure the general ease-of-use of components & features:

  • Consistency: verify consistency of icons, images, logos, etc.
  • Ease-of-use: verify navigation, UI workflow, simple/intuitive UI

These would include the following activities:

  • Evaluate Wireframes & Mockups
    • Review wireframe/design concept with design team & stakeholders to match requirements.
    • Review UI & Usability for UI elements & components like search, data grid, navigation, workflow & ease-of-use.
    • A/B Testing
    • Review digital branding & the overall appearance.
  • Review developed UI
    • Heuristic evaluation (follow Heuristic checklist)
    • Verify cross-browser/device compliance (responsive layouts)
    • Validate semantic coding standards
    • Perform end-user testing:
      • Measure/Evaluate the number of steps required for completion of critical tasks.
      • Measure/Evaluate number of clicks required for retrieval of critical information.
      • Evaluate intuitiveness of data representation.
  • Establish Client Labs


  • Increased end-user productivity levels.
  • Reduced time on task completion.
  • Intuitive UI by reduction in learning curve and reduced errors.
  • Fewer clicks, less mental load and simplified navigation.
  • Ensures that any potential issue is highlighted and fixed before the product is launched.
  • Increases the usage and repeat usage of the product.
  • Minimizes the risk of product failure.
  • Ensures that users are better able to reach their goals, resulting in business meeting its targets.
