That quote is attributed to Peter Drucker (although he might not have said it exactly like that).
Regardless of origin it is a truth. All the strategy, planning, training and implementation is worthless in comparison to a strong culture. All those pieces will come together when your culture is motivated and committed.
Easy to say, hard to do. The proof of an organization culture is found in every interaction, every detail and more importantly in every crisis when the true nature is revealed. We’ve heard how every HR team is improving the culture with their wellness program, or some benefit. Those might provide short term perks but it’s the long term consistency that defines the culture.
How’s your culture?
