استخدام منهجية Lean Six Sigma في تحسين أداء العملية : دراسة حالة في الشركة العامة لصناعة الأسمدة البصرة-خور الزبير

Abstract EN

Purpose: The main purpose of this research is to explore opportunities to integrate manufacturing practices with its processes using the LSS methodology to reduce waste and variability, improve efficiency and enhance quality and thus to improve the process performance.

Design/Methodology/Approach: The LSS methodology was systematically applied to eliminate waste and to improve the performance of the current process.

The steps included assessing the current state of the company through tracking the process and collecting basic data through the interviews conducted by the researcher, which came through sites visits and prepare processs map to limit the waste and the reason behind reducing for provement .The data were collected by using a set of quantitative measures in which a computer program designed with Microsoft (Excel 2010) as well as the statistical program (SPSS v.17) and finally Develop and put Control plan to ensure continuity and improvements.

Findings: The rates of utilization of the product design capacity were low, as well as the low levels of efficiency, and productivity.

The company suffers from the deviation of the urea product at the reactor stage from the required specifications, the main reason is not using exact rates of raw materials inside interacting, as well as the obsolete equipment and not use of modern equipment with advanced technology.

It was also concluded that the application of the LSS methodology would reduce delivery time.

Obstacles to the study: The difficulty of obtaining information, especially the defective production of the final product.

Originality/Value: This study was used to fill the gap in the lack of use and application of the LSS methodology.

The Arab studies on the Six Sigma approach did not use the DMAIC model to improve performance and only presented it with the theoretical framework
