Application of quality tools to solve the problem of inadequate management of chemical products case study: Sonatrach Maintenance Directorate – Laghouat

Abstract

This research aims at applying a problem-solving methodology by using quality tools to solve the non-conformities related to the management of chemical products at the Sonatrach Maintenance Directorate (DML) in Laghouat. The problem is related to the lack of safety data sheets (SDS) and the ambiguity of the expiration dates for the product (WD-40). We based ourselves on a qualitative, analytical study. We conducted a field case study within the organization, through semi-structured interviews, observation and analysis of documents, which allowed us to have an in-depth understanding of the current situation and to make an accurate diagnosis of the problem. The research was based on a series of basic quality tools that are used in the problem-solving methodology, such as: 5W2H tool, Brainstorming, Ishikawa diagram, and “5 Whys” method. The Action plan and findings of the research, it was found that the problem is mainly due to poor organization, weak mechanisms for controlling the inventory, and lack of awareness of the safety requirements. The results also showed that the absence of a clear problem-solving methodology contributes to the recurrence of the same problems without an effective solution. Based on this, a set of immediate and corrective actions was proposed and structured in an Action plan with the aim of correcting the current situation and preventing the recurrence of non-conformities, through the strengthening of controls, the improvement of the documentation system and the intensification of awareness and training. This study highlights the importance of integrating quality tools into the daily practices of organizations, as they have an effective role in supporting decision-making and improving performance.
