  • Learnability

  • Effectiveness: It is a measure of how well the design supports/ enables its users to accomplish what they are supposed to do on the website such as tasks/ goals without any problem. It enables users to do what they want to do. For example, browsing and purchasing books, making a phone call, uploading images and broadcasting them etc.

  • Efficiency: It is a measure of how much time and effort it takes to complete the task using the design. For example, Amazon 1 click payment, Single Sign on etc.

  • Memorability: It is a measure of how easy a design is to remember that even after a long period of time, you are still able to complete the tasks/ goals effectively using the design without any problems. For example, Amazon payment, opening a door, using an ATM etc.

  • Errors: It is a measure of how the design prevents user from making errors as well as enabling users to recover from errors if they have committed one. For example, typos, wrong ID number and passwords etc.
