When leaders work together you don’t only get things done but there are other benefits too:
Synergy. You create something greater than the sum of all the parts.
Momentum. You make forward progress. Not just little steps either but leaps forward.
Appreciation. You see the value that each person brings to the table.
Soaring with Strengths. You soar with your strengths while others soar with theirs.
Vision is Accomplished. You see what you are dreaming for becoming a reality as you work on it together.
Culture Created. You build the culture of the organisation rather than forcing it.
I’m sure there is more. What would you add to the list?
