Where functional testing ends and usability testing begins

The talk closes with several questions that arise in custom development processes and in small product teams:

• Whose area of responsibility is ergonomics: the test engineer, the designer, the UX researcher?
• If the right specialist is not on hand, how do you conduct consistent usability testing?
• How to fix the results of usability testing?

The talk includes case studies and backlog tasking. Best practices and stories of failures.
