Imagine those core value posters, with keywords like Integrity, Respect, and Customer First. Not that they are wrong, but when core values are defined as such, they are not helpful. No company aspires to NOT have integrity. When defining core values, we must test them against dilemmas our employees will face on a day to day basis. It is when they are guided to resolve everyday dilemmas that we build our organisation culture.
Imagine you work at a creative company. You have started work on a piece of art. Do you show it to your supervisors and colleagues now, so that you can get their feedback and course-correct early if necessary? Or is this going to take up everyone's time unnecessarily since your work is still early-stage? At Pixar, they have one clear principle - show your unfinished work. If you work for Pixar, you know clearly what to do.
Frame your core values through dilemmas, and you will build your organisation culture more effectively.
