Guidelines and checklists help ensure that usability principles will be
considered in a design. Usually, checklists are used in conjunction with
a usability inspection method--the checklist gives the inspectors a basis

Nielsen, in the book Usability
Inspection Methods, lists a small set of usability guidelines as follows:

Flexibility and efficiency of use
Aesthetic and minimalist design
Help users recognize, diagnose, and recover from errors
Help and documentation
