DoD can break from the program-centric model to develop and acquire capabilities in a broader portfolio aspect. Expanding on the systems-of-systems construct, programs can manage requirements, research and development, contracts, budgets, resources, architectures, roadmaps, and many other acquisition aspects at a broader portfolio level. Monolithic systems can be divided into smaller incremental pieces and managed along with related capabilities to regularly deliver capabilities to users. This approach has the potential to improve the efficiency and effectiveness of major acquisitions. See the article Think Portfolios, Not Programs in Defense AT&L Magazine.
