Core values to the workplace
Bring your organization's core values to everyday work practices.
Core values are an important aspect of a strong culture. But how do you make sure the people in your organization know what the core values are? That those are worn? And that people actually act on it in the many dilemmas of daily work practice? Because until people do something with it on a regular business day, it's just some pretty empty words on a website.
Bring core values to life in your organization with lessons from the Rockstars Method, facilitated by Double-OO. In a 100-day program from words on the website to concrete actions in line with widely held core values. Want to know how? Feel free to ask us.
