The lack of such linkages has then resulted in firms using initiatives in a piecemeal manner and misunderstanding their impact, that is their potential or long-term impact. This paper is aimed at identifying quality improvement practices in the transportation industry in Kwara, Osun and Oyo States, categorizing them and linking them with performance outcomes. To achieve this, primary data on quality practices and measures of performance in the transportation industry was collected through administration of questionnaire for Kwara, Osun and Oyo states. Groups of Quality Constructs (Initiatives) were formed using factor analysis and Success of Transportation Quality Programs (STPQ) regressed on the Quality Constructs identified. The result showed that five Quality Constructs were paramount Quality Practices in the industry of which four are found to be significant to Success of the Transportation Quality Program (STPQ).enQuality Construct, Quality Practice, Service IndustryArticle
