Which statement is false regarding requirements checking techniques?

Field observation is not typically considered the most frequently used checking technique for requirements verification. While it can be valuable in specific contexts, such as in user experience assessments or understanding user needs, it is not as widely employed as other techniques like inspections, reviews, or testing methods.

In contrast, effective techniques like inspections involve structured evaluation and can yield substantial insights into the requirements, making them more prevalent in practice. Other common techniques include reviews and walkthroughs, which facilitate collaboration and thorough examination of requirements. Therefore, the notion that field observation ranks as the most frequently used is misleading, which makes the choice regarding this statement incorrect.
