In 2005, the Canadian Forces (CF) changed the way Regular Force members acquire Distinctive Environmental Uniform (DEU) items: a monthly monetary allowance, known as the Clothing Upkeep Allowance (CUA), was replaced with a clothing replacement system based on the individual accrual of points. The costs of the DEU clothing system have increased in the years since its change from the CUA-based system to the points-based system. The Directorate of Materiel Group Operational Research (DMGOR) was tasked in September 2009 by the Deputy Chief of Staff Materiel (DCOS(Mat)) to examine if the reported difference in the costs of the DEU clothing system is due to increased demand by the DEU clients. Per-capita turnover rates were calculated for several major groups of DEU items in the old system and the new system, and for each it was determined if these rates have changed with any statistical significance using Wilcoxon-Mann-Whitney tests. Statistically significant differences were found between the turnover rates in the time periods under the two different DEU systems for 7 of the 29 groups of items studied (and a further test was inconclusive). Hence, significant changes in the overall demand of DEU items on a per capita basis were not found to be widespread. With respect to costs of the system, it was found that changes in the population of the DEU clients have been responsible for approximately 30% of the increases of costs of the DEU system, with the majority due to the increased n
