Congrats to the editors and contributing authors of the Defense Acquisition Research Journal (ARJ) for publication of Issue #100! With a theme of “100th Issue Retrospective”, articles in this new April 2022 issue include:

• Consolidation of the U.S. Defense Industrial Base - A former Deputy Secretary of Defense discusses acquisition reform and the wisdom of downsizing/rightsizing the defense industrial base at the turn of the 21st century.
• Adaptation of Porter's Five Forces Model to Risk Management - In this article, the author presents typical systems engineering models such as the work breakdown structure, functional flow block diagram, and risk reporting matrix, and explains how they are analogous to organizational hierarchies, enterprise flowcharts, and uncertainty matrices, respectively. Particular emphasis is placed on risk management and the associated adaptation of a strategic management model called the Five Forces Model.
• The High-Flying Leadership Qualities: What Matters the Most? - The author makes the case that when it comes to leadership, leaders underestimate, fail to notice, and/or prematurely dismiss how they ignore certain leadership traits to the detriment of their organizations. Demographic factors too can easily influence how leaders/subordinates judge certain leadership qualities through their personal experiences and exposure to various situations.
