A manufacturer needs to reduce the percentage of nonconforming keyboards on its best-selling ergonomic, split keyboard. The production team suspects that most of the defects, such as sticky keys and stiff space bars, can be isolated to assembly, but needs to baseline the current process before making any changes. Which measure(s) should be used to assess process capability?

The waste related to diagnostic tests is an opportunity for hospitals to decrease costs. The manager of a trauma unit at one hospital just launched a Six Sigma project aimed at reducing redundant diagnostic tests, with an expected cost reduction of 10%. Which tool should the team use to gain agreement on project boundaries and scope? 

Part 1 of 2 Parts A manufacturer of wooden rulers must reduce the percentage of defective rulers of its #1 best seller – the “-12” model which displays both 12 inch and 305 mm scales on the same side! Each ruler is inspected for four defects: too long, too short, blurred markings, and rough finish. Workers pulled a random sample of rulers, and found rulers with a total of defects. Estimate PPM. (Express answer as “per million”)

Part 2 of 2 parts Based on the process performance index, Cpk, estimated in Part 1, does this process meet Motorola’s definition of Six Sigma quality?

The waste related to diagnostic tests is an opportunity for hospitals to decrease costs. The manager of a trauma unit at one hospital just launched a Six Sigma project aimed at reducing redundant diagnostic tests, with an expected cost reduction of 10%. Which tool should the team use to visualize the process steps connected to the Customer?  

Who proposed the “Theory of Latent Defects”?

Based on the above figure, If is a price ceiling, then the number of units of a good that will be exchanged at the price ceiling (i.e., ) is:

Based on the above graph, Total surplus (TS) is ________________ in a market with a price floor (i.e., ) The market is not allowed to move to equilibrium. 

Based on the above graph, Consumer surplus (CS) is ________________ in a market without any price controls.  The market is allowed to move to equilibrium.
