The challenge: How do you get usability feedback from your audience?
Usability is defined by the effective, efficient, and satisfactory achievement of specific user goals. Lack of testers prevents companies from obtaining fast, valid results that are quickly interpretable and can pinpoint problematic usability areas. This is especially important when testing needs to comply with standardized questionnaires, or when the performance of each release needs to be benchmarked.
The solution: Quantitative data for greater comparability
The Quantitative Usability Study gathers insights and validates usability by using quantitative data from your target group. In this service, testers from your target group will be asked to use core features of your digital product and take part in a quantitative survey. Using quantitative methods allows quick and frequent feedback about your digital product.
Scientifically validated benchmarks we offer
|NPS (Net Promoter Score)||Popular at the management level to measure the recommendation rate of the product|
|SEQ (Single Ease Question)||Simple but effective question to get feedback on difficulty at the use case level|
|UEQ (User Experience Questionnaire)||Semantic differential that measures six dimensions of the user experience (26 questions) - available in 22 languages; short version with ten questions available (UEQ-S)|
|AttrakDiff||Semantic differential that measures four dimensions of the user experience (28 questions); short version with eight questions available (AttrakDiff mini)|
|SUS (System Usability Scale)||Most widely used usability questionnaire|
| SUPR-Q (Standardised User Experience |
Percentile Rank Questionnaire)
|Questionnaire that measures the user experience using four dimensions and nine questions (currently only available in English)|
In addition, common metrics such as effectiveness (percentage of users able to successfully complete the use case) and efficiency (time taken for a user to successfully complete the use cases) can be measured.
If you plan to use other benchmarks or use others internally, you are welcome to make a request.
How it looks in practice
50 testers from your target group perform five core tasks on your website. After they finish these tasks they rate their likelihood to recommend your website with a Net Promoter Score (NPS) – “How likely is it that you would recommend this website to a friend or colleague?” on a scale from 0 (not at all likely) to 10 (extremely likely). All testers responding to this question with a 9 or 10 are so-called “promoters”, testers responding with a 7 or 8 are “passives”, and testers responding between 0 and 6 are “detractors”.
To calculate the NPS you simply subtract the percentage of detractors from the percentage of promoters, resulting in a score ranging from -100 to 100. There are benchmarks available, for example for consumer (B2C) and business software (B2B) to compare your results to. If your consumer product has a NPS of 5 you can put this number in meaningful context since consumer products have an average NPS of 23. This data indicates that your product is below the average ratio of likelihood to recommend and should be improved in order to be able to compete on the market.
