SOA and Event-Driven Architecture (EDA)

I was just thinking about these concepts and how they relate to public sector organizations like the US DoD.  It seems to me that private sector organizations bring themselves into existence, there is a struggle for "life" with multiple competitors, a constant struggle for resources constrained by natural laws,but freely available,  therefore a constant "evolutionary pressure".  In this type of environment organizations must be concerned with how best to utilize their own parts and pieces to maximize or optimize their growth rate.  Therefore, rapid, effective response to changes in the business environment in which they operate is highly desirable.  Among the benefits of SOA and EDA are organizational flexibility and agility in the context of the competitive business environment.  In the US DoD, the environment is quite different.  First, the organization did not bring itself into existence nor does it remain in existence simply by its own efforts or struggle for "life".  The concept of competitor is irrelevant because a competitor, by definition, threatens to end another's existence by taking more of the common resources that each competitor requires in order to remain in existence.  Furthermore, resources are not constrained by natural laws, nor freely available, so that resources are not truly the mediating factor influencing the existence of public sector organizations. What does all this mean with respect to SOA and EDA efforts in the US DoD?  I believe it means that the success or failure of these projects is much more subjective and difficult to judge.  These types of organizations must carefully choose judgement criteria based on their operating environment.
