Which of the following are not competitive advantages of lean operations?

-Staying up-to-date with customer's changing taste and demands -Constantly staying up to date on the latest manufacturing equipment and robotics

How is GE using additive manufacturing?

-They are creating engine parts that weigh less, cost less and employ more intricate designs. -They are making fuel nozzles as a single part instead of assembled in 18 pieces. -They are testing procedures out on many different part of the next generation 777 engine.

Which of the following are critical processes for implementing lean techniques?

-eliminate process waste -eliminated waste time and space

Additive manufacturing . . .

-is making it possible to create designs or stuctures that weren'e feasible using traditional manufacturing processes. -enables the creation of materials with multiple moving parts and components without assembly. -affects everyone who works with manufacturers and participates in the creative process design. -ALL OF THE ABOVE

Which of the following are trends that are causing an upheaval in the manufacturing setting?

-more adept machining components - low cost and accessibility of Big Data -Software and communication technological advances -The decline in the cost of electronic sensors -ALL OF THE ABOVE

The concept of lean six sigma:

Joins lean practices and quality practices

Connecticut Consulting Company (CCC) helps diagnose and solve quality production problems. Their most recent client has several out-of-control samples; but CCC recommended against costly root cause analysis since the process was still producing parts well within specification limits. Did CCC make a sound recommendation based on current quality control best practices?

No

Which of the following was the successful strategy Lululemon employed to combat their quality problems?

None of them were

In order to adapt the TPS to other cultures, the eight waste of ________ was added.

Not utilizing peoples talents

Frank and Eva Mae are inspecting the quality of the record cutting process in their boutique vinyl shop. They have had some complaints that recent records had more glitches during playback. They map the quality of some sample records on a control chart and they can see a trend seems to emerge that more records show glitches although they are still well within the control limits of their specifications. An argument ensues because Eva Mae is determined to investigate with their staff due to these shortcomings in quality. Frank thinks there is no need for action because the process is within control limits. Which of the following are valid arguments in this discussion?

The glitches might indicate special cause variation and warrant further investigation. Trends should always be taken seriously, even if control limits are not breached.

Zara manages is supply chain risk through:

Using flexible factories Buying capacity from suppliers so that the suppliers can respond quickly

Which of the following is not a dimension of product quality?

Tangibility

Lean was started as:

-An offshoot of the quality movement after WWII -As Toyota wanted to emulate Ford's efficiencies without huge inventory build-up it saw at Ford.

What is quality?

-Performance relative to expectations -Judged by customers along multiple dimensions

If the population production mean is exactly at the target production level and the Process Capability Ratio is 1, how far from the mean is the upper specification limit?

3 sigma

Technological advances in manufacturing has allowed Jay Leno to manufacture entire cars in his own automobile shop.

True

Companies should use the upper and lower specification limits as control limits.

False

The most common root cause of quality problems (identified with the assistance of the Pareto chart) is ALWAYS the best one to target for quality improvement

False

A larger Process Capability Ratio is generally preferred over a smaller Process Capability Ratio.

True

A process to make strike-anywhere matches produces matches satisfying length specifications. The matches must be shorter than 2.5" to fit in the match box, and the matches must be longer than 2.0" so that the customers don't scrape their hands while lighting the matches and so they don't burn their fingers while trying to use the lit matches to light campfires. The average length of matches produced is the same as the target length of matches and is equal to 2.25". The standard deviation for the matches produced is 1/18". What is the Process Capability Ratio?

this answer is 1.5, but he wants us to use 1
