What's our sentence?

Can we define our organization's purpose in one sentence?

Google's is "We organize the world's information and make it universally accessible and useful"

"This is not a tag line but a single idea that defines the company's reason for existing. Discover what your company is best at and put it into a sentence." (From Harvard managment's tip of the day)

What are we best at? What is our organizations number one reason for existence? Where do we add the most value?

It's not good enough to be pretty good at everything. You have to be the most of something

What is our

definitive statement about the difference (we) are trying to make in the world
