- 1. experts in every digital area
- 2. What is user testing? • A qualitative research method where user behaviour is observed. • Aim is to understand what people do with minimal interference from the method itself. • Focus is on collecting data (evidence) directly (not indirectly via a survey or analytics). • Can be formative (informs design decision) or summative (evaluates the finished product).
- 3. “Supposing is good, but finding out is better.” User testing benefits: • Less risk • Inform decision-making • Drives innovation • Recognise latent user issues • Exposure to real users
- 4. Aren’t you supposed to be an expert? • Designers are not your users. • Every business needs to understand the goals, motivations and behaviour of its users. • Is my guess correct?
- 5. User Testing works • A 28% faster average completion time for tasks and an overall 37% reduction in the number of usability problems (Tan et al, 2001) • Reduced task time and increased user satisfaction (Bailey and Wolfson, (2005); LeDoux, L.C., Connor, E. and Tullis, T.S. (2005))
