Product Usability Testing in Singapore
Usability test definition
Usability testing refers to a series of methods that are used to improve usability in the design process. We provide our users with a series of operational scenarios and tasks for them to accomplish, which are closely related to your product or service. Through observation, we find out what problems arise in the process, what functions and modes of operation users like or dislike, and why. In response to the problem, we will make suggestions for improvement.
The value of usability testing
The value of usability testing lies in early detection of problems that users will encounter in your product or service, giving suggestions for improvement before product development or production, helping you improve your product and save on development costs with less investment.
Usability test development time
Depends on the degree of product design.
Usability testing methods
1.One-on-one user test: a usability test section includes testers (moderator/assistant) and a target user, the target user will be accompanied by testers to complete a series of typical tasks. The testing process will be photographed with the consent of the participants, testers will continue to observe and understand the user’s operation process, thinking the process and related indicators (including the number of user errors, the time to complete the task, etc.), record the user encountered Usability issues and analysis.
2.Heuristics Evaluation: We invite 5–8 users as assessors to evaluate the human-computer interaction in the use of the product, identify problems and propose improvements based on the usability design principles.
- Heuristic Evaluation is a content usability check that is used to discover the usability issues in user interface design that make these issues a part of the redesign process.
- The heuristic approach to assessing the usability of each discovery is based on established usability principles, so a revised design is based on the design criteria laid down in the principles that have to be met by a good, interactive system that has been violated It is quite easy.
- According to Nielsen’s (1994) study, in general, five evaluators were able to detect 75% of the availability problems, which is the ideal figure from the ratio of the market value to the cost of assessing the usability issues.
3.Focus group: composed of the 6–12 creative small group, under the guidance of a host to discuss a topic or idea. Inspire ideas and thoughts with the interaction of the participants to deepen and complete the discussion. In usability testing, the focus group can be used to compare existing models and modify the suggested discussion.
Usability test latitude
Typical usability tests include the following latitudes: success rate of task operations, task operation efficiency, user expectations before task operations, user reviews after task operations, user satisfaction, task error rates, success rate of secondary operations, Identification of the user operation of the cognitive latitude (depending on the product situation) and so on.
Usability test time spent
Typical usability testing requires 2 weeks of pre-communication and preparation, 1 week of testing, and 2 weeks of submission of analysis reports. According to the test content and project size to make adjustments.
