This Plan Do Check Act is a four-stage iterative process for continuously improving processes, products, or services and resolving problems. Plan Do Check Act entails testing potential solutions systematically, analyzing the results, and implementing the ones that have proven to work. Many effective EHS management systems use the Plan-Do-Check-Act method, which defines the actions an organization should take to plan, implement, review, and continuously improve their management system. This method emphasizes continuous improvement and applies to all processes within an organization. The PDCA cycle, first proposed by Walter Shewhart and later developed by William Deming, became a widely utilized framework for continuous improvement in manufacturing, management, and other fields.
