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.
