Six Sigma is a project management and process improvement technique focused on reducing errors, defects, and variability in processes. Its main goal is to improve quality by identifying the root causes of problems and eliminating them through data driven analysis.
The term Six Sigma refers to a quality level where processes produce very few defects. Each sigma level represents how often defects are likely to occur. At lower sigma levels, processes are less stable and produce more errors. At the Six Sigma level, the process is highly controlled and produces extremely consistent results with minimal defects.
Six Sigma provides project managers with a structured approach to problem solving. It helps measure performance, analyze inefficiencies, and implement improvements based on clear metrics. One of the key advantages of Six Sigma is its focus on measurable results and long term process stability.
This technique is widely used in industries where quality and precision are critical. Common areas include manufacturing, healthcare, finance, logistics, and large scale IT operations.
If a project requires predictable outcomes, strong quality control, and continuous improvement, Six Sigma can be a strong choice. It helps teams reduce waste, improve customer satisfaction, and build reliable processes that scale over time.
