Usability Engineering

Usability is mainly concerned with human computer interaction designing human interfaces
to have high usability, or friendliness. With large and complex systems, this is
a very important part of the overall design and implementation. With a couple of
our projects we have developed very usable wizards, for the facilitation of online
document drafting. These wizards’ guides one through various steps, and only shows
the user the forms, questions or boxes for their specific needs, which are calculated
on a per use basis. This avoids confusing a user by showing them only what they
need to see, otherwise if you show all available questions and content the user
gets confused and the process breaks down.

Usability can be seen from a top down perspective building all the components to
work together, creating a complete and usable system. It can also be seen from a
bottom up perspective, focusing on the small parts, on a by page basis, such as
using radio buttons to specify gender on a form instead of a dropdown.

Usability engineering is a very import part in the web development process, to insure
you get maximum conversions from traffic generated.

Bad usability = Poor conversion rates.
