We have examined our many therapy relationships for commonalities and have found a large group of them, important enough to the business world to codify and share them.  This is our playbook for productivity. 

At its core is a set of 18 basic behavior patterns that heighten work-flow and reduce resistance.  They can be identified and expanded in the repertoire of any employee.  They can be taught and shaped by appropriate feedback, and if they are supported by the company as a whole, they can increase more quickly. 

This is how we understand the  company.  It holds the power to spark accelerated learning.
