Fundamentally, the objective of the campaign should be clear and link back to your brand and brand voice. All elements of the campaign need to be consistent in voice. Have one person signing off on all elements and set clear goals, targets, KPIs etc for the team.
Have a schedule and plan that is accessible to all, brief all relevant members of your team and always be clear about what you set out to achieve.
Prepare to be fluid.
Ensure reporting is set up for each element and that there is a debrief during and post campaign to understand what worked and what didn’t so you can tweak accordingly along the way.
