Are you trying to get greater clarity on your goals or your organization's strengths? Do you want to communicate those goals more clearly to your team or your strengths more clearly to your clients?
The Thiagi Group has developed a list of "Concept Analysis Questions" that my friend Gayle Carney, founder of cctsbaltimore.org, found useful. It helps the user see where he has enabled scope creep, such that he is no longer focused like a laser on his goal but instead his focus has spread to seemingly related, but not useful, activities. I recommend going through the questions with your team, or at least a partner, so that you have others with whom to brainstorm.
Give it a try and let us know how it goes.
