Core values and principles describe HOW you and everybody in your organization go about things. They shape the culture, which is a key factor for long-term success. Defining them will help you take hiring and people leading decisions, they will translate to your brand image and influence your marketing and customer service and how you are perceived by everybody if you take them seriously and actually live up to them.
So no, they shouldn’t be just nice words you put up the wall for inspiration, they should actually guide your and your team’s behavior and attitude, they should be something you all connect with, want to live up to and try to demonstrate every day.

So what is it that you value?
