Change Management and Agile Project Management

I came across a great explanation on the virtue of agile project management in the context of change management.

"I believe agile projects accommodate this uncertainty better.  Fixed time boxes equal fixed schedule.  Dedicated full-time team equals fixed budget.  Scope is left flexible.  The customer prioritizes scope.  If you focus on highest business value first, delivered in regular intervals within a fixed budget, does i really matter if the scope changed?"

I found this quote from Jennifer Bleen to be a very concise way of conceptualizing the advantage of agile project management.  The quote also helps illustrate when the agile project management method is most appropriate to use (projects with fluid business requirements).
