What is Lean Sigma?

The term combines two quality improvement approaches: Lean and Six Sigma. Lean methodologies focus on eliminating waste and streamlining processes. Six Sigma projects involve increasing quality and yield while reducing defects and variation. 

Why Use Lean Sigma?

  • It doesn’t force organizations to choose between quality of care and saving money. Lean Sigma projects often boost the bottom line while improving care and reducing the chance of patient safety errors.
  • It is grounded in measurement and statistical rigor, helping participants to develop plans of action that are backed by data.
  • It puts quality improvement tools in the hands of frontline providers, who are familiar with the inefficiencies and hazards facing their patients, so that they can be catalysts for organizational change.
  • It results in projects that more often have a significant business case, due to the requirement that teams identify the benefits up front when creating their project charter.
  • It encourages sustainable, long-lasting improvement, through its focus on setting up measurement systems and then consistently tracking and feeding back performance.
