work.
ii.
Laboratory Usability Testing: Observers and Test Engineers do
testing in separate lab room.
Five 5 Test Engineers are
enough to uncover the 80% usability errors or issues.
Usability
Testing - Best Practice: Need to start on early stage of development. Test Engineers should be
properly educated and experienced. One observer need on each Test engineer.
Merits
and De-merits of usability testing:
i.
Satisfaction of end user
ii.
Uncover the usability bugs on time
iii.
Highly efficient and effective system will be maintained
Demerits:
