Good business reasons
Usability as a Business Strategy
- sources below
For every $1 spent on usability, companies achieve between $10 and $100 of product benefit.

E-commerce sites can lose half their potential sales, if their customers can't find merchandise.

Content sites can lose 40% of potential return visitors if the site's usability is poor.

Find serious problems early: it will cost you 100 times less to fix usability problems before launching, than after you have launched your product.

Usability improvements can improve user productivity by 25%, improve user morale, reduce documentation costs, reduce training costs, and reduce customer care costs.

Usability as part of the design process can improve your brand image, customer satisfaction, and customer retention.

Usability engineering has demonstrated reductions in product-development cost and time of 33-50%.
