How NOT to start your presentation on change

Senior leader... standing at the front of a room, about to announce some key information on a change and transformation piece of work.
The room is hushed. Everyone is waiting to hear why the change is happening and how it will affect them. You know the old 'WIIFM' 'What's in it for me'. You've got to hook them in first, before you even begin to blab on about how it will roll out and when it will happen.
So the leader begins... and the first words out of their mouth were:
'I have seven slides to present'.
Yep, that was it. The number of slides. The number of times they were going to 'click' the clicker to advance the PowerPoint deck of pre-prepared numbness. Seven times.
THAT was the most important thing?
That's what you wanted to lead with?
That was going to frame the change, the message, the impact?
The nervousness, uncertainty or anxiety was leaking out of this leader and their subconscious or unconscious was speaking: 'just get through these seven slides'.
The team thinking - 'oh great, seven slides.'
After some wise counsel on how this leader could design, communicate and facilitate change through the rest of this national rollout, the start of the subsequent presentations changed.
This leader started with a story, or a statistic, or a statement. It was inspiring, engaging and it captured attention.
They didn't start with the number of slides. Not any more.
Know your message.
Know your team and their 'what's in it for me'.
Lead with that. Reinforce that.
Share that and be passionate about that.
Not how many slides you have. (zzzz)
