A Study of the Material Inspection Record and Quality Systems: A Case in the United States Department of the Navy

摘要

Defective products and services are a part of every industry, sector, and organization. Minimization of those defects is essential for business success. The later those defects are found, the more they cost the business and consumer. This study investigated the impact having an accredited Quality Management System (QMS) had on the acceptance of delivered product. The study focused on the products delivered to the Naval Sea Systems Command (NAVSEA) and Naval Supply Systems Command (NAVSUP) organizations. This study investigated the statistical significance between the means of the groups within size and number of accreditation. The dependent variables were Material Inspection Record (MIR), units received, and units rejected, or products delivered to the NAVSEA and NAVSUP organizations.;The study used the PDREP Metric Dashboard data for fiscal year 2012, quarter 1 through fiscal year 2016, quarter 2, resulting in more than 8,000 records analyzed and interpreted using a one-way ANOVA and General Linear Model.;The results of the analysis indicated there were no significant differences between size or accreditation of organizations, when compared to the number of rejected units and Material Inspection Report (MIR) acceptance or rejection. The analysis did suggest there is statistical significance when size and accreditation are compared to MIR acceptance or rejection (F-Value 3.01, P-Value 0.006). Additional analysis was conducted for within group comparisons and small organizations were identified as having a statistically disproportionate percentage of units rejected (76.61 percent), when compared to the percentage of units received (55.24 percent). Within small organizations, organizations with one accreditation had the highest ratio of units rejected compared to units received (2.00 to 1) as a percentage of units received within small organizations. Further research was recommended to explore other factors that would improve risk assessment and mitigation within the Department of Defense (DoD).
