It all starts with the idea to be in an organization in which people are willing to walk the talk. That is, they live up to the values and the mission of the organization they are working for.
That isn’t an easy achievement. It means for example that everyone is accountable for walking the talk, not only the leader. It also means, that people are aligned individually with the mission and the values the organization stands for.
Achieving this means having an organizational culture in which these values are embedded. Not only through a mission statement or a list of values, the company adheres to, but also through many details in which these values find themselves applied. Doing this work means regularly reviewing existing processes in the organization to see how they correlate with the existing values and behaviors they require. The more this work is done, the better the values are being understood by everyone.
It naturally also means to act on situations in which values are not lived up to as expected. There is no excuse for keeping people who don’t behave according to the values just because they are experts in an important field or seemingly established themselves as irreplaceable.
