Abstract: New computer and communications technologies have the potential to revolutionize the battlefield. However, developing battlefield command systems that take advantage of these new technologies before they become obsolescent is a challenge for procurement professionals. Traditional acquisition strategies are inherently inflexible, therefore not well suited to these systems with their high rate of technology advancement and often volatile user requirements. Evolutionary Acquisition (EA) is a new strategy, recently introduced in the Australian Defence Organization, with the potential to deliver these systems more efficiently. This paper provides an overview of the principles behind EA, the characteristics of systems suited to the EA approach and the benefits that can be achieved. The challenges in successfully completing an EA project are also discussed.
