Measurement Development
Seven constructs were evaluated: information security policy, top management support,
organizational learning culture, institutional policy, system quality, service quality, and
organizational benefits. Measurement items derived from past studies were reworded to
relate specifically to ELS in the organizational context. The review and refinement of the
items by two MIS professors secured content validity. A pilot test was conducted; questionnaires
were sent to 30 companies that had introduced ELS and 20 companies responded.
Measurement items were then revised according to their responses and are shown in the
Appendix.
