Document Summary
A strategy to improve process quality by identifying and eliminating defects and minimizing variation. Goal: attain less than 3. 4 defects per million opportunities (dpmo: dpmo = (# of defects in a sample / total # of defect opp. ) = # of defects in a sample / # of units sampled. **control x to control y: assumption that over time, processes may increase in variation, shifted = original + 1. 5 . Dmaic: define define the problem, measure map out the current process, analyze identify the cause of the problem, improve implement and verify the solution, control maintain the solution. Elements of define: what dmaic projects are not: New process design projects (use dfss design for six sigma) Projects that are simple/quick (use lean/kaizen: pareto priority index. % success) + (total cost * eta: a3 tool. Entire plan for problem solving on one paper (a3 11 x17 ) Keep process improvement close to work (gemba)
