Dr. Larrie D. Ferreiro

Chairman Larrie FerreiroThe theme for this edition of the Defense Acquisition Research Journal is “The Method Matters.” The lead article is “Survey of Modular Military Vehicles: Benefits and Burdens,” by Jean M. Dasch and David J. Gorsich, which goes a long way to defining the often-misunderstood word “modularity” and provides a balanced look at the benefits and drawbacks of this acquisition methodology. Acquisition methodology is also at the heart of a classic article from the Summer 1995 issue of the Acquisition Review Quarterly, entitled “Technology Approach: DoD Versus Boeing (A Comparative Study),” by A. Lee Battershell. The author examines how the market-driven approach to development—where cost and schedule dominate decision making—contrasts with the military’s performance-driven approach and how each one can affect development time.

Survey of Modular Military Vehicles: Benefits and Burdens

Jean M. Dasch and David J. Gorsich

Modularity in military vehicle design is generally considered a positive attribute that promotes adaptability, resilience, and cost savings. The benefits and burdens of modularity are considered by studying historical programs dating back to World War II. Using a taxonomy developed at the U.S. Army Tank Automotive Research, Development and Engineering Center, vehicles were considered based on horizontal modularity, vertical modularity, and distributed modularity. Examples were given for each type, including the most extensive attempt at horizontal modularity in the 1980s, known as the Armored Family of Vehicles. Following these examples, various cost/benefit studies over the life cycle of the vehicle are reviewed with differing conclusions depending on the initial assumptions. Finally, a number of design factors are included that should be considered in any program on modular vehicles, as well as some recent initiatives that guide the path forward.

Technology Approach: DoD Versus Boeing (A Comparative Study)

Author: A. Lee Battershell

This is an analysis of different approaches in the use of technology by Boeing and DoD to determine how they may have affected development time for the C-17 and the Boeing 777. Boeing’s focus on cost, schedule, performance, and market competition is contrasted to DoD’s focus on performance. The paper concludes that the mere existence of a technology should not obscure (a) the impact its maturity may have on program cost and risk, (b) whether it will meet a real need of the user as opposed to a gold plated one, and (c) whether the added development time it may require could pose unanticipated problems for the customer, or even result in fielding obsolete weapons systems.

Tapping Transaction Costs to Forecast Acquisition Cost Breaches

Authors: Laura E. Armey and Diana I. Angelis

This article uses transaction costs to predict the probability of incurring a cost breach in a major defense acquisition program (MDAP). As transaction costs are not explicitly measured for MDAPs, the authors use estimates of systems engineering and program management (SE/PM) costs as a share of overall program costs as a proxy for transaction costs. Using survival analysis, a new approach to predicting cost breaches, they also found that an increased share of SE/PM costs in initial program estimates can help predict future cost breaches.
