#13: Company values, organically created.
Within a company, the values of its culture are not those that are written but rather the values that are regularly modelled and rewarded. Note also: what is not rewarded? What behaviours are punished?
Just as written language followed millennia of spoken tradition, so too should defined values follow and reflect organisational behaviour.
That is not to say values cannot change — but that change will not come with a list of values alone.
