As the new general manager in an office of 70+ staff I had this sign on my wall as a reminder to myself and my team.
In previous roles I had all too often observed the tendency to spot a problem, determine a solution and then spend an inordinate amount of time arguing over the solution with others in the team. And too often the argument was fueled by disagreement over choosing the solution. As I watched these arguments unfold it became clear often people wanted to win or be right. To be fair many wanted the result, but didn't want to be wrong or be seen to "lose".
So when an argument erupted I would ask which solution got us to the result. If it was both then we could argue the merits of both... to get the result. By staying focused on the result and moving away from winning or being right we got better solutions, better relationships and... fewer problems.
