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

Describe SPC and Acceptance Sampling.What is the key difference between the two?

Briefly explain THREE of the statistical tools of Six Sigma.

Acceptance sampling is a statistical technique that enables a shipment reject or accept decision to be made based on information obtained from a representative sample drawn from the population.

When designing a manufacturing or service process, a Pareto chart would be an essential tool for evaluating the process in terms of its action elements, waiting periods, and process flow.

The Quick Response program, developed in the 1980's, was an offshoot of the following supply chain concept:

The primary design objective with lean layouts is to reduce wasted movements of workers, customers, and/or work-in-process.

Which of the following are among the MOST important elements of the lean production philosophy?

Lean production is an operating philosophy or mindset that essentially attempts to minimize the impact of system variability and flaws in forecasting through the use of high safety stock inventories.

A company sells eggs in boxes with 12 cartons and 12 eggs in each carton, thus there are 144 eggs in each box.The organization wants to construct a P-chart to track the proportion of broken eggs in each sample (shown below).If the company used one box of eggs in each sample in the dataset below, what would be the centerline, upper control limit (UCL), and lower control limit (LCL) for the appropriate P-chart? (Use z = 3.) Choose the closest answer.

Which of the following is NOT one of the Seven Wastes?

Some of Deming's 14 points actually conflict with many Six Sigma concepts.

When compared to their U.S.counterparts, a benchmarking study found that Japanese auto manufacturers used:

Which tool is useful for presenting data in an organized fashion, indicating process problems from most to least severe:

A Nevada Bank keeps track of errors from 20 clerks.Each sample has 100 records.They want to construct a P-chart to track the proportion of errors in each sample.The table below shows the number of errors per sample.(Use z=3 for control limit calculations.) a.Determine P. b.Determine σP. c.Determine the 3-sigma UCL and LCL. d.Does the process appear to be in statistical control?

The following is a term that refers to error or mistake proofing:

Statistical process control (SPC) allows firms to compare process performance to desired levels or required standards.

Waste in Japan is also referred to as:

The Five-Ss refer to:

Which person was a key figure in developing the Toyota Production System and also developed the concept of poka-yoke?

When lean firms share their best practices with supply chain members, this is referred to as yokoten.
