Usability

Usability encompasses multiple components that change over time as technology develops. However, it is generally agreed that there are five usability attributes:

  1. Learnability: systems should be easy to use and allow individuals to get started quickly
  2. Efficiency: systems should be efficient to use
  3. Memorability: systems should be easy to remember
  4. Errors: systems should have low error rates
  5. Satisfaction: systems should be pleasant to use

In addition, three principles ensure usability:

  1. Consistency
  2. Controllability
  3. Predictability

Systems should be easy to learn, so that users can quickly start working. 2. Efficiency . Systems should be efficient to use, so that users can quickly increase their productivity. 3. Memorability . Systems should be easy to remem- ber, so that users can quickly reacquaint them- selves with the system if time has elapsed since they last used the system. 4. Errors . Systems should have low error rates; if users do make errors, they should be quickly cor- rectable. 5. Satisfaction . Systems should be pleasant to use, so that users are not reluctant to work on them. Usability supports, rather than hinders, people’s creativity. Three general principles help to ensure usability:
