In order to successfully implement your strategy, you must bring on board partners, and create meaningful partnerships. A partnership is a combination or alliance, especially a temporary one between distinct parties, persons, or states for joint action.
Think of how raindrops are created, by the union and coalition of water vapor into. Raindrops are a body formed by the coalescing of originally distinct elements.
The same goes for partnership building. It is about coming together to form a stronger whole.
