Timing makes a difference. Don't launch on a Friday afternoon. By Monday it's already old news. Choose a moment when you get maximum attention: the start of the week, the start of the quarter, or a date that has meaning for your organisation.
Make sure everything goes live at the same time: website, social media, email, internal systems. That synchronisation is logistically challenging but essential. A half-baked transition period undermines the impact of your launch.
And start preparing in time: at least ten weeks. More about timing and planning in our article on organising rebranding events.
