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 to achieve near-perfect performance, typically defined as 3.4 defects per million opportunities. The methodology is structured around the DMAIC (Define, Measure, Analyze, Improve, Control) framework for existing processes and DMADV (Define, Measure, Analyze, Design, Verify) for new processes.
Developers should learn Six Sigma to enhance their ability to optimize software development and IT processes, reduce bugs, and improve overall project efficiency and quality. It is particularly valuable in roles involving DevOps, quality assurance, or enterprise software development where process standardization and data-driven decision-making are critical, such as in large-scale Agile or Lean environments.
