Data come from carefully validated, standardized questionnaires which are filled out by members of the top 2-3 tiers of business management in each major unit of the company. Senior IS staff also fill out a survey form dealing with IS matters.
Definitions vary by company.
We counsel with you on how best to define appropriate units. Usually it's a major piece of the business organization. Retailers would have merchandising, distribution, stores, and administration. CogniTech can slice the data several ways to gain maximum analysis power. We price according to the number of units selected by the client for analysis.
