Whether you're landing on the moon or growing a manufacturing business, your mission statement must be audience focused.
Most companies think of a mission statement as the mission of the company. For example, we see a lot of mission statements that start off with “We offer high reliability and added value .” Another common phrase is “Our company mission is profitable growth through superior customer service, innovation, quality, and commitment.” Here's another one “Our mission is to become the leading provider of blah, blah, blah.”
The one thing most of these mission statements have in common is that they are about what the company wants to be, do, or offer. They ignore the target audience. They try to match what they think their customers want to the mission statement. There may or may not be a place for this type of mission statement at your company; you will have to decide.
