Skills needed before learning Six Sigma include attention to detail, analytical abilities, strategic thinking, and strong verbal and written communication. Six Sigma requires an ability to observe and understand current conditions and to find ways to bridge the gap between these and the ultimate standard. Six Sigma teaches students how to identify the root causes of issues and waste and follow a consistent methodology to address them. This includes gathering the necessary data, forming the right teams, and identifying corrective actions that can be immediately implemented. Time is often of the essence, and many of the problems addressed require quick solutions.
