Jakob Nielsen's usability research indicates that the number of testers involved in usability testing is not solely dependent on economic factors. The true essence of his findings emphasizes the importance of usability testing for any project, regardless of its size or budget constraints. Effective usability testing can significantly improve product design and user satisfaction, which might require a varying number of testers based on the project's goals, target audience, and specific usability objectives.

Furthermore, Nielsen’s insights suggest that while budget considerations are pivotal, other factors such as the complexity of the design being tested, the diversity of user profiles, and the specific insights required from the testing can all influence how many testers are needed. This more nuanced understanding highlights that effective usability testing necessitates a consideration of multiple factors beyond just economic constraints, making the assertion about it being solely dependent on economic factors inaccurate.
