When selecting a continuous improvement methodology, it is important to consider factors such as your industry, culture, customers, complexity, urgency, and resources. Commonly used methods include Lean, Six Sigma, Kaizen and PDCA. Lean focuses on eliminating waste and maximizing value for customers. Six Sigma is data-driven and structured and is designed to reduce variation and defects. Kaizen encourages small and incremental changes while PDCA is a cycle of Plan, Do, Check, Act. Combining or modifying these methods, such as Lean Six Sigma or Kaizen Blitz, can also be beneficial depending on your context and goals.
