The short answer is: it depends on your goals. If you Google “focus group,” you will have a host of positive and negative feedback, but the truth is that it depends on what your needs are. What Is a Focus Group? Focus groups are an inexpensive way to identify people’s preferences, motivations, thoughts, feelings and attitude towards a product or service. In a typical focus group, approximately 6 to 10 people spend 60 to 90 minutes voicing their opinions about your website or application.
It’s a forgone conclusion that usability studies are effective in identifying weak points within a website, but what about testing people who are visually impaired? How hard is it to accommodate them? There are some additional challenges that you may encounter when conducting testing with people with disabilities; however, these challenges should not be considered overwhelming. I spoke with Peter McNally, a Senior Usability Consultant at the User Experience Center at Bentley University, to get his take on usability testing with users who have visual impairment.
