System of Profound Knowledge
The Deming System of Profound Knowledge® (SoPK) is the culmination of Dr. W. Edwards Deming’s lifelong work. It is an effective theory of management that provides a framework of thought and action for any leader wishing to transform and create a thriving organization, with the aim for everybody to win. By management appropriately applying the principles and practices of SoPK, a business can simultaneously reduce costs through reducing waste, rework, staff attrition and litigation, while increasing quality, customer loyalty, worker satisfaction and, ultimately, profitability.
SoPK ties together Dr. Deming’s seminal theories and teachings on quality, management and leadership into four interrelated areas: appreciation for a system, knowledge of variation, theory of knowledge and psychology.
The PDSA Cycle (Plan-Do-Study-Act) is a systematic series of steps for gaining valuable learning and knowledge for the continual improvement of a product or process. Also known as the Deming Wheel, or Deming Cycle, the concept and application was first introduced to Dr. Deming by his mentor, Walter Shewhart of the famous Bell Laboratories in New York.
