The 4H's become part of the DNA of the company. It is the framework for how we hire, onboard, review and terminate employees.  We also use the 4H framework when evaluating partners, suppliers, customers and investors.  For example, our review process has four questions:
1. What did you do?
2. What are you going to do?
3. How can we help?
4. How are we doing against our values?
This process (thanks to Pat Lencioni) is a great way to reinforce values in a systematic way each quarter.
