Abstract
This paper develops and validates an attitudinal scale that can measure the performance of e-commerce operations both in "pure play" Internet firms and in on-line components of multichannel firms. The measurement instrument is grounded in a resource-based view of the firm. The final instrument contains a 14-item perceptual measurement scale. It was tested with data collected from a sample of 595 managers responsible for e-commerce operations. Psychometric testing of the instrument showed adequate construct validity.
