This document discusses segmenting industrial markets using a nested approach with five levels of criteria from general to specific:
1. Demographics (easiest to assess) such as industry, company size, location
2. Operating variables like company technology, user/non-user status, capabilities
3. Purchasing approaches including function organization, power structures, policies
