Is your website usable?
If your job depends on getting a definite answer to this question, then you should start using the System Usability Scale.
The System Usability Scale (SUS) was invented by John Brooke who, in 1986, created this ‘quick and dirty’ usability scale to evaluate practically any kind of system.
The SUS has been tried and tested throughout almost 30 years of use, and has proven itself to be a dependable method of evaluating the usability of systems compared to industry standards.
