Every time I hear that an organisation is hoping to bring about culture change, or perish the thought “driving culture change”, my heart sinks. You can’t change culture. You can change things that affect people in the hope that doing so gives them a good reason to adapt their behaviour, but culture emerges from the collective behaviours of the people in your organisation over time.
The worst scenario is when those “driving change” don’t change their own behaviours but start producing shiny posters telling everyone else how to behave. Doing so is likely to bring about a rapid change in your culture but not in the ways you intended!
