Good post. I've also heard an Alliance referred to as a "Personal Board of Directors" as it relates to your personal effectiveness.  This is a group of close trusted advisors who are transparent and give it to you straight.  No hidden agendas.  No fear of reprisal.  They help you see your blind spots, offer different perspectives, and listen when you need a sounding board.  Sometimes this is a coach or mentor, or it can be a former colleague, or even a professional contact with whom you've never directly worked.  These personal alliances can prove to be very useful in ensuring you are successful in forming and managing your business alliances.
