The Role Of The Strategy (S5) In Product Quality An Applied Study Of The Opinions Of A Sample Of Workers In The Production Department Of The Midland Refineries Company

The authors aim from the current research to investigate the role played by the strategy (S5) in the product quality within the company under research and clarify the relationship of correlation and influence between the research variables. In order to achieve this purpose, the authors designed a hypothetical chart to clarify the nature of the relationship between the research variables. Also, they adopted the descriptive analytical approach, where the field aspect of the research was applied in the Central Refineries Company, as the study sample was chosen intentionally to obtain the best results, as the sample size was (196), and 196 questionnaires were distributed, which only 182 were retrieved. Fourteen forms were excluded because they were unsuitable for analysis, so 168 forms remain subject to statistical analysis, and the total response rate by respondents was 85.7%. A set of statistical tools were utilized to test the research hypotheses, including (a normal distribution test, confirmatory factor analysis, reliability coefficient (Cronbach's alpha), Pearson correlation coefficient, and structural equation modeling). It was based on a set of ready-made programs for statistical analysis, including (SPSS V. 23) and (Amos V. 23) program. This work reached several conclusions, the most important of which is the existence of a positive, statistically significant correlation and effect between strategy S5 and product quality.
