Exam 8: Process Management: Lean and Six Sigma in the Supply Chain

While the philosophy of Six Sigma means different things to different people and is practiced differently in different companies, according to the textbook, two of the more important and agreed-upon elements of Six Sigma are:

Manufacturing cells are often U-shaped to make operator and material movements easier within the cell.

The element of lean involving firms working with buyers and customers with the mutual goal of eliminating waste, improving speed, and improving quality is referred to as:

Provide an overview of the beliefs of each of the following quality professionals: W.E.Deming Philip Crosby Joseph Juran

Organizations practicing lean production often increase their inventory levels in the long-run in order to create a cushion against variability so that they can investigate and eliminate the weaknesses of their system.
