Six Sigma
Six Sigma is a data-driven methodology and set of tools for process improvement and quality management, originally developed by Motorola in the 1980s. It aims to reduce defects and variability in business processes by using statistical methods and a structured approach (DMAIC or DMADV) to achieve near-perfect performance, typically targeting fewer than 3.4 defects per million opportunities.
Developers should learn Six Sigma when working in roles that involve process optimization, quality assurance, or cross-functional projects in industries like manufacturing, healthcare, or software development, as it helps improve efficiency, reduce errors, and enhance customer satisfaction. It is particularly useful for identifying root causes of issues, implementing data-backed solutions, and fostering a culture of continuous improvement in team workflows.
