Handbook of Management Scales/Product competitive advantage
Product competitive advantage (alpha = 0.88)
Although certain items of some scales were developed specifically for the Japanese context, many were derived from existing validated scales. Respondents answered all questions using a Likert-type scale ranging from 0 to 10; field research suggested that an 11-point scale was appropriate for studying Japanese management practices because a 100 percent grading system is used in most Japanese schools.
Product competitive advantage refers to a product's perceived superiority relative to competitive products. It concerns the product's technical performance and quality, as well as the degree to which it meets customers' needs with unique features and capabilities.
To what extent does each statement listed below correctly describe this selected successful project? (0 = strongly disagree, 10 = strongly agree)

The items were evaluated on a scale ranging from 0 to 10. However, the observed mean value is 7.09 rather than 5. It might therefore be recommendable to change the wording.
