Six Sigma is recognized for its systematic approach to improving business processes by focusing on reducing variation and defects within those processes. It employs a set of quality management tools and techniques, primarily rooted in statistical analysis, to identify areas for improvement, implement changes, and measure the impact of those changes.

The methodology involves defining what constitutes a defect in a process and the customer's needs, measuring current performance, analyzing data to determine root causes of issues, improving processes based on findings, and controlling future performance to sustain improvements. This cyclical process known as DMAIC (Define, Measure, Analyze, Improve, Control) is fundamental to Six Sigma's approach.

In contrast, while ITIL (Information Technology Infrastructure Library) focuses on aligning IT services with the needs of the business, and COBIT (Control Objectives for Information and Related Technologies) provides a framework for developing, implementing, monitoring, and improving IT governance and management practices, they do not specifically emphasize process improvement in the same statistical and data-driven way as Six Sigma. ISO 27001 is an international standard for information security management systems, which is more about managing and protecting information than directly focused on improving business processes. Thus, Six Sigma stands out as the most relevant framework for systematically improving business processes.
