>>> Speed up the design process: Early resolution of debates over features to include and how they
should be implemented saves wasted effort. Concentrate resources
on the areas of the design that support the business objectives.
>>> Increased efficiency: Customers want to get the job done and
get on with their lives; they will thank you for it. Even small
decreases in the time taken for employees of large companies to
complete frequently performed tasks can add up to enormous savings.
>>> Decrease support costs: Bad usability results in the need
for expensive customer support and/or user training, e.g. helpline
support can cost in excess of $100 per call. It is also much easier
to produce self-help documentation for a usable
system.
