Abstract
Background
The pharmaceutical industry is continuously striving to enhance operational efficiency. Variability in production, particularly during the tablet compression phase, presents significant challenges to maintaining consistent product quality. The Six Sigma DMAIC methodology has emerged as an effective approach for addressing these process inefficiencies.
Objective
This paper aims to apply the Six Sigma DMAIC methodology to improve the tablet compression process for AMOF625 tablets, with the goal of reducing variability and enhancing overall product quality.
Methods
The DMAIC framework was employed in the following phases: Define: Critical areas contributing to non-conformance were identified. Measure: Eight months of historical data were analyzed to identify patterns of variability in the process. Analyze: Rootcause analysis was conducted using statistical tools, including control charts and fishbone diagrams, to pinpoint the sources of variability. Improve: Solutions such as automating procedures and enhancing worker training were implemented to address the identified issues. And Control: To ensure sustained improvements, controls including continuous monitoring systems were established.
Results
The implementation of the Six Sigma DMAIC framework led to substantial improvements in process capability. Notably, sigma levels increased from 3.05 to 5.4 in the powder stage, reflecting a significant reduction in variability. Additionally, product quality metrics showed considerable improvement.
Conclusions
The application of Six Sigma effectively reduced process variability and enhanced product quality in the tablet production process. This study highlights the importance of Six Sigma principles in driving continuous improvement within the pharmaceutical manufacturing sector, demonstrating its potential for achieving sustained quality enhancements.
