In Egan's work on the "shadow side" of organizations, he defined the shadow side as:
All those things that substantially and consistently affect the productivity and quality of the working life of a business, for better or worse, but which are not found on organisation charts, in company manuals, or in the discussions that take place in formal meetings.
