|Helps to identify the real issues.||Helps to identify the potential/hidden issues.|
|Specific or limited tasks are performed by the user.||Predefined guidelines & checklists are defined and evaluators have to stick with that.|
|‘Screen-by-screen’ approach is used by testers to test the system.||Whole system is evaluated by experts in a systematic manner.|
|Helps to improve the functionality of the programs.||Helps to improve the overall user experience by thorough evaluation.|
|It is costly because it involves a lot of user participation.||It is cheaper and faster than conducting full-blown usability testing.|
