Well stated, Lisa.  Early on, in my own entrepreneurial adventures, I had the privilege of working with an excellent organizational development coach. I was exposed to those basics of org dev, vision, mission, and values. All of the great books on modern business thinking point to it as well, Vision is the lynchpin, the locus, - the source of meaningful business. If anything, the challeng is to be able to help solve organizational sticking points, but always returning to the vision. Bill Clinton's campaign famously posted a statement over their campaign door (on the inside)- "it's the economy, stupid". In other words, stay on track. When you take to your vision the way an Airedale takes to a rat, you've got some real power.
