Six Sigma is based on a set of key principles and methodologies that organizations follow to achieve process improvement and drive results. These principles and practices include:
    1. Six Sigma relies on data and facts to make informed decisions and drive improvements. It emphasizes the collection, analysis, and interpretation of data to identify areas for improvement and measure progress accurately.
 
    • Six Sigma aims to improve business processes systematically. It emphasizes understanding and optimizing each step of a process to reduce variation, eliminate defects, and enhance overall performance.
 
    • Six Sigma emphasizes meeting and exceeding customer expectations. It focuses on understanding customer needs, preferences, and requirements, and aligning process improvements to enhance customer satisfaction.
 
    • Six Sigma promotes a culture of continuous improvement. It encourages organizations to constantly evaluate and enhance their processes, striving for ongoing innovation and excellence.
 
    • Six Sigma provides a structured problem-solving methodology known as DMAIC (Define, Measure, Analyze, Improve, Control). This methodology guides teams through the process of identifying and defining problems, measuring key metrics, analyzing root causes, implementing improvements, and establishing control measures to sustain the gains.
 
    • Six Sigma encourages collaboration and involvement from various departments and stakeholders within an organization. It recognizes that process improvement requires input and participation from individuals with different perspectives and expertise.
