The purpose of this study is to examine the degree of influence supply chain factors exert on wait times for medical supplies to the Operation Enduring Freedom and Operation Iraqi Freedom theaters. A multivariate, regression analysis was used to test five hypotheses involving sixteen predictors of wait times. This research is important because reductions in wait times facilitate Army transformation and the Armys ability to win wars. Twelve months of scores were collected and means, standard deviations, and correlations were and examined for each variable. A regression analysis revealed beta coefficients, f scores, and probability scores for the hypotheses tested. The descriptive statistics for the dependant variables indicate that intransit time is the source of variation in both customer wait time and requisition wait time. ANOVA tests for each hypothesis revealed identical significance test scores f 11,0 0, p. .05. The null hypothesis for each test was accepted and alternate hypotheses were rejected. Colinearity among the independent variables reduced the error score for each analysis causing low f scores.
