There are three common mistakes. First: sending too much and leaving too little room for response. Second: presenting the change as a done deal while people are still in the denial phase. Third: forgetting the follow-up. A change event without concrete follow-up actions leaves people with more questions than answers.
Another pitfall: organising the event separately from the broader communication strategy. The event must fit into a continuous story, not stand as an isolated moment. Live Impact helps think through the coherence of the entire change communication.
