  • Explain the three pipeline systems. Toggle to highlight the 43 districts and 7 divisions. We are not one uniform culture but rather a composite of 43 cultures . Each work team is its own culture. If we follow small teams within that district, they each have their own culture and way of working with each other. If we add our engineering teams we have even more cultures. Cultures change one person at a time, one leader at a time and one work team at a time.
