• Learnability - How easy for the users to accomplish the basic that they encounter the design for the first time?
• Efficiency- The users have learned the design and how quickly the users can perform their tasks/responsibilities?
• Memorability: After a period of not using it the users return to the design and how can they reestablish proficiency easily?
• Errors: How do users make many errors, how these errors

  are severe, and how can they recover from the errors easily?
• Satisfaction: How the design use in a pleasant way?

  business nowadays and people like to see that

  sure font size is big enough, the actual font itself is

  appropriate, and your colour-scheme makes it easy to read

  what’s on your website.
