註釋Since 2002, Air Force Materiel Command (AFMC) has implemented best purchasing and supply-chain management (PSCM) practices at its Air Logistics Centers (ALCs) that support fielded weapon systems through the acquisition, repair, and overhaul of equipment, among other things. PSCM is the implementation of best business practices for purchasing logistics support from private-sector sources and government organizations. Its goals link to Air Force goals to improve aircraft availability and reduce the total cost of support. The goals of the Air Force PSCM initiative are to improve supply material availability -- the right parts at the right time -- reduce material costs, and reduce the time it takes to provide materiel to Air Force base supply locations. Along with investments in PSCM -- which have included reorganizing the way the Air Force purchases support from the private sector; training personnel to these new practices; constructing new analytical tools; and most important, writing contracts as a product of these practices -- the Air Force has wanted to know if, and how much, PSCM was benefiting the warfighter. That seems logical and straightforward, but since this particular initiative was not the only one being launched at the same time, the Air Force wanted to be able to determine whether or not this particular initiative was, by itself, producing the desired results. After all, because not "all other things" were being "held constant," some of the other changes might have influenced or even been more responsible for any outcomes, good or bad. The authors refer to these simultaneous changes as "co-occurring factors." They addressed this challenge by extending an econometric model to account for these factors. This monograph describes the resulting methodology and illustrates it by applying it in a National Item Identification Number (NIIN)-level analysis of quarterly mission capable (MICAP) incidents in the context of AFMC's own PSCM initiative.
