USABILITY BUSINESS CASE
A usability test costs from 25.000 up to 75.000 DKK and usually improves
conversion rates around 20 – 50 % (sometimes as high as 200 – 500 %).
An e-shop has the following data:
Annual turnover: ~ 2,5 million DKK
Unique visitors: ~ 225.000
Annual sales: ~ 4.500
Is it worth investing in a usability test if it costs 50.000 DKK and improves
conversion rate with 10 %?
