However, the problem lies in the fact that a large number of Iraqi companies, especially industrial ones, have not adopted this method and may not have an awareness of its importance and how it works.
The general company for petrochemical fertilizers in Basra was selected as a field to demonstrate the feasibility of applying this method. It was found that by applying six sigma the percentage of defects in production will be 6.67% and 92.4% accuracy. This will reduce the cost of failure because it is directly related to the company's sigma .
