The balance between pace and being nice is a really tricky one.
This is really about enhancing Leadership team capabilities and creating the right organization culture to make it happen.
Let me begin by saying: The center of Leadership is about "influence"... and the center of influence is about "relationship".
It goes back to the relationship of Leadership team with employees at all levels in the organization which will motivate and inspire employees to "always do their best for the organization, even when no one is watching". To do that, you need to give them a BIG WHY that is really relevant to them.
The pace will be much better once, they feel motivated and empowered.
