In the early 90's, I worked for Insync Systems, Inc. in the San Francisco Bay Area. They were an Inc Magazine Top 500 company which prouded itself in cutting-edge technology and innovated business solutions and ideas. They had adopted this "different" way of communicating with their internal and external customers. We all felt like we were speaking a foreign language.
Now, more than 20 years later, I find I still use the valuable skills I learned with the "Conversations for Action" process. I've found it lessens miscommunication, affords one the ability to decline requests, and adds a level of respect to all conversations.
I even brag of its usefulness to my current bosses and peers.
