Usability Engineering

Preface

Software

developed in recent years has been devoting an average

of

48%

of the code to the user interface [Myers and Rosson

1992].

It

would

thus

seem justified to allocate a reasonable proportion of the

effort

in software development projects to ensuring the usability of

these user interfaces. This book tells you

what

to do if you decide

to improve usability.

The

main goal of the book is to provide concrete advice and

methods

that

can be systematically employed to ensure a high

degree of usability in the final user interface.

To

arrive at the perfect

user interface, one also needs genius, a stroke of inspiration, and

plain old luck.
