5S as a Lean Tool in a Validation Laboratory in Puerto Rico

Abstract

The target of this study was to investigate the application of the 5S improvement methodology in a Validation laboratory to determine the impact on test efficiency. The investigation was conducted using a single-case study approach in a Validation laboratory. Quantitative data was analyzed using statistical analysis tools for BCT test times per process step and laboratory technician before and after implementing the 5S. Qualitative data were gathered from the workforce through questionnaires before and after the tool's implementation. The study substantially improved laboratory test efficiency and employee engagement after applying 5S. Overall, test efficiency increased to 86.4% after the implementation of 5S. This investigation provides additional literature on the efficiency improvement process in a laboratory setting using the 5S improvement method. Future studies should utilize a bigger sample size or extend the multiple areas to increase the reliability of the findings. Keywords - 5S, Improvement, Laboratory, Test Efficiency.
