Only customers can make a company profitable, so connect all your BPI-related talking points back to this fundamental core. Call BPI something else that resonates in your company, if necessary. Often the name you decide to use makes a difference in the acceptance rate at a company.
The ultimate goal is to make business process improvement part of your company’s DNA. You cannot change your DNA; it is inherent in who you are as a human being.
