The Differences Between Usability and User Acceptance Testing and Why Both are Important for Successful Software Development

Conclusion:
Involving end-users in the software development cycle isn’t a new concept, yet reportedly, 78 per cent of IT project professionals believe business stakeholders need to be more involved in and engaged with the requirements process1. Commonly, software development project managers report problems with end-users’ ability to learn and use the new system and/or the end-users’ perceived quality of system functionality. While usability testing is meant to be a safeguard for system ease-of-use, user acceptance testing is designed to be a safeguard for the development of quality functionality. Both play a different role in the software development lifecycle.
This paper covers the differences between usability testing with end-users and user acceptance testing, also conducted with end-users and why both are equally important for the software development success.
