Enterprise architecture is a relatively new concept that arose in the latter half of the twentieth century as a means of managing the information technology resources within the enterprise.  The goal of this research has been to discover strategies that can attenuate the difficulties that result from wicked problems, complexity, and the enterprise learning curve and also improve the likelihood of developing an enterprise architecture that delivers a positive return on investment for the enterprise.  Towards this goal, this research establishes: the focus and scope of enterprise architecture by defining the bounds of what enterprise architecture should address; develops a core set of enterprise business questions from which to begin enterprise architecture development; develops an enterprise architecture metamodel that supports enterprise architecture metamodel development; and develops a methodology that aids the enterprise architect in focusing the development effort on obtaining significant value while reducing the risk of expending resources developing architectural artifacts of little or no value.
