This study aim is to prove the flexibility of lean six sigma using the DMAIC method in reducing the amount of time spent on auditing, findings, and reporting in a logistics service firm. The Six Sigma is a data-driven, disciplined technique and methodology for reducing defects in any phase aiming for six standard deviations between the mean and the closest design limit, modeled within the DMAIC method (Define, Measure, Analyze, Improve and Control). DMAIC is a method for improving, optimizing, and securing business processes and designs. A major component of Six Sigma tools is the DMAIC improvement phase. The research focuses on identifying the time spent on the auditing process of value-added and non-value-added. The secondary data was then collected by asking/interviewing the auditor. Using the Lean Six Sigma DMAIC approach, the information was analyzed for audit process quality and audit time reduction. Upon the implementation of improvement solutions, the time can be reduced with the current process from the improvement stages through lean six sigma approaches. The company was able to use its lean six sigma implementation skills to make significant improvements, saving time, and money, and improving quality. The study assesses previous research and makes recommendations for future studies.
