10 rules to design things that are perfectly adequate
Usability Principles
42. 1 Recognition rather than recall
Usability Principles
Place items on the page where and when users need
them as they move through the system.
Don’t force people to remember things.
46. 2
Match between system and the real
world
Usability Principles
Speak the user’s language.
Use familiar words, phrases and concepts,
rather than system- or business-oriented terms.
49. 3 Consistency and standards
Usability Principles
People have used hundreds of interfaces before they
arrived at yours.
They’ll be expecting certain patterns of how things
should be named and how they work.
55. 5 Emergency exits
Usability Principles
Users often make mistakes.
Help users avoid disaster by providing escape hatches
and “undo” functionality.
58. 6
Help users recognize, diagnose, and
recover from errors
Usability Principles
Error messages should be expressed in plain language,
precisely indicate the problem, and constructively
suggest a solution.
61. 7 Visibility of system status
Usability Principles
The system should always keep users informed about
what is going on, through appropriate feedback within a
reasonable time.
65. 8 You are here
Usability Principles
Interfaces should answer the question:
where am I, and where am I not?
Process interfaces should show the number of steps,
progress, and the expected duration.
71. 9 Flexibility and efficiency of use
Usability Principles
Design a flexible interface that can be used by both
novice and advanced users.
Allow users the freedom to explore content, and a
reasonable amount of control over their experience.
77. 10 Minimalist design
Usability Principles
The elements of an interface’s design should not
obstruct its function.
Every extra piece of information competes with the
relevant bits of information and diminishes their
visibility.
