Chairman Larrie Ferreiro

The theme for this edition of Defense Acquisition Research Journal is “…All Others Must Bring Data.” It derives from the famous quote by American management consultant W. Edwards Deming, “In God we trust; all others must bring data,” displayed outside the office of Under Secretary of Defense for Acquisition, Technology, and Logistics Frank Kendall. Accurate and meaningful data are the basis for making informed acquisition policy decisions; as British scientist William Thomson (Lord Kelvin) said over a century ago, “When you can measure what you are speaking about … you know something about it; but when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.”*

Authors: Kevin Buell, Mustafa G. Baydogan, Burhan Senturk, and James P. Kerr

The specialized nature of technology-based programs creates volumes of data on a magnitude never before seen, complicating the test and evaluation phase of acquisition. This article provides a practical solution for reducing network traffic analysis data while expediting test and evaluation. From small lab testing to full integration test events, quality of service and other key metrics of military systems and networks are evaluated. Network data captured in standard flow formats enable scalable approaches for producing network traffic analyses. Because of its compact representation of network traffic, flow data naturally scale well. Some analyses require deep packet inspection, but many can be calculated/approximated quickly with flow data, including quality-of-service metrics like completion rate and speed of service.

Where Are the People? The Human Viewpoint Approach for Architecting and Acquisition

Authors: Holly A. H. Handley and Beverly G. Knapp

The U.S. Department of Defense Architecture Framework (DoDAF) provides a standard framework for transforming systems concepts into a consistent set of products containing the elements and relationships required to represent a complex operational system. However, without a human perspective, the current DoDAF does not account for the human performance aspects needed to calculate the human contribution to system effectiveness and cost. The Human Viewpoint gives systems engineers additional tools to integrate human considerations into systems development by facilitating identification and collection of human-focused data. It provides a way to include Human Systems Integration (HSI) constructs into mainstream acquisition and systems engineering processes by promoting early, frequent coordination of analysis efforts by both the systems engineering and HSI communities.
