Donna Maurer has written a nice overview of what usability is – and what it's not. She outlines the process used during a user-centred development project and defines the qualities of usable systems.
To Maurer, the primary disadvantages of user-hostile systems are:
- If the system is difficult to use, people won't use it
- If people have to use a difficult system, they will do so as little as possible
- People will waste time
- More support is necessary
- A user-hostile system is likely to require changes
