Implementing Six Sigma Methodology to minimize errors in the preparation of outbound documents: A case study of an export company located in Chonburi Province

Abstract

The preparation of outgoing documents is a critical process in business operations, especially in organizations that regularly send documents to customers, service providers, or other agencies. Errors in outgoing documents can affect customer relationships and result in financial losses. The application of Six Sigma principles can help reduce errors and improve the efficiency of document preparation processes. This article is the result of a case study conducted with a private company in the maritime transportation sector. This article aims to study the application of Six Sigma principles to reduce errors in the outgoing document preparation process by using the DMAIC framework. The study begins by identifying problems that occur in the preparation of outgoing documents, such as errors in customer data entry or incorrect printing of important documents. Then, Six Sigma tools such as Pareto Charts, Fishbone Diagrams, and Control Charts are used to analyze the causes and identify methods for process improvement. The study results show that the application of Six Sigma significantly reduced errors in the outgoing document preparation process, reducing the error rate by 40% within one month after implementation. Additionally, the document preparation process became faster and more efficient, leading to more continuous business operations and substantial reductions in costs associated with error correction. The findings of this research can be applied to organizations that prepare outgoing documents in order to improve process efficiency and reduce errors that may occur in their operations.
