Model for Improvement
“The definition of insanity is doing the same thing again and again and expecting a different result” Albert Einstein
Scientific Method Analytic in nature with the focus on the development/discovery of new knowledge
What are we trying to accomplish? How will we know that a change is an improvement? What change can we make that will result in improvement? Model for Improvement ActPlan StudyDo Langley, et al.
Langley et. al PDSA Learning Cycle: Most important part of any PDSA cycle is the Prediction as it represents current knowledge about how a process or system will behave in the future. When predictions are compared with actual outcomes they can reveal gaps in our current understanding of why a process or system behaves the way it does This comparison/examination generates knew knowledge about what change might work or what modification is needed Inductive learning begins here

Final Thoughts on PDSA The opportunities for learning about many aspects of the change from testing are expected to be significant, including learning from failures. Some percentage of tests—perhaps 25 to 50 percent—is expected to result in no improvement, to “fail,” but to result in substantial learning nevertheless. 9 Langley et al

PDSA Simulation
PDSA Measures Accuracy 3 – All pieces on Mr. P & positioned correctly 2 – All pieces on Mr. P, but one or more is out of place 1 – One or more pieces are not on Mr. P. Time Start: When time keeper says go. Stop: When Assembly indicates last piece is in place AND removes hand.
