What is the best way to write a vision & mission statement for any company?

When you're coming up with the concept for your business, an important component of your overall strategy plan is a mission statement. This brief statement declares the purpose of an organization and defines the reason for the company's existence. It provides the framework and context to help guide the company's strategies and actions by spelling out the business's overall goal. Ultimately, a mission statement helps guide decision-making internally while also articulating the company's mission to customers, suppliers and the community. 

A vision statement for a company or organization focuses on the potential inherent in the company's future, or what they intend to be. While a vision statement might contain references to how the company intends to make that future into a reality, the “how” is really part of a "mission" statement, while the vision statement is simply a description of the “what,” meaning, what the company intends to become.
