The DMAIC model consists of the initials of the steps that form the basis of the approach: Define, Measure, Analyze, Improve and Control.
Define
In this phase of the Six Sigma approach, the scope of the project is clarified, the problem at hand is fully defined and goals are set in line with customer expectations. This way, the entire team involved knows from the outset what problem they need to solve and what the criteria for defining success are.
Measure
The current status and performance evaluation of the quality improvement process are measured with numerical data. Concrete data obtained through measurement and analysis reveals the frequency of errors made during the production phase and their impact on production, thus determining the actual appearance of the production process.
Analyze
The resulting concrete data is examined to determine the root causes of errors occurring during the production phase. Once errors are precisely identified through data analysis and statistical methods, work begins on how to improve them.
Improve
Solutions to production errors are developed based on data obtained through analysis and investigation, and roadmaps are created for their implementation. Improvement improves quality and increases efficiency by optimizing the production process and reducing errors.
Control
To ensure the quality achieved through the Six Sigma approach remains sustainable, new standards are established and adopted by every employee at every level of the company, and the process is regularly monitored. This control mechanism ensures the preservation of the gains achieved through Six Sigma and prevents the company from encountering similar errors in the future.
