CPS Analysis & Optimization 5

Question 1

A healthcare process team uses a Spaghetti diagram during analysis. What does this tool primarily reveal?

Accepted Answer

Physical movement paths of people or materials

Answer

A Spaghetti diagram traces the actual physical paths traveled by people, materials, or information, exposing excessive movement waste.

Question 2

Which metric best quantifies the overall performance of equipment by combining availability, performance efficiency, and quality rate?

Accepted Answer

Overall equipment effectiveness (OEE)

Answer

OEE multiplies availability, performance, and quality percentages to give a single composite measure of how productively equipment is used.

Question 3

A process optimization team wants to reduce the number of input variables to investigate in a DOE. Which technique screens many factors to identify the vital few?

Accepted Answer

Plackett-Burman design

Answer

Plackett-Burman designs are resolution III screening designs that efficiently evaluate many factors with relatively few experimental runs.

Question 4

In a pull system, production at each step is triggered by:

Accepted Answer

Downstream demand signals (kanban)

Answer

Pull systems use kanban signals from downstream operations to authorize upstream production only when replenishment is needed.

Question 5

When a process has a Sigma level of 3, approximately what percentage of outputs fall within specification limits?

Accepted Answer

93.32%

Answer

A 3-sigma process yields approximately 93.32% of outputs within spec, corresponding to about 66,807 defects per million opportunities.
