A healthcare process team uses a Spaghetti diagram during analysis. What does this tool primarily reveal?
Answer: Physical movement paths of people or materials
A Spaghetti diagram traces the actual physical paths traveled by people, materials, or information, exposing excessive movement waste.
Which metric best quantifies the overall performance of equipment by combining availability, performance efficiency, and quality rate?
Answer: Overall equipment effectiveness (OEE)
OEE multiplies availability, performance, and quality percentages to give a single composite measure of how productively equipment is used.
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?
Answer: Plackett-Burman design
Plackett-Burman designs are resolution III screening designs that efficiently evaluate many factors with relatively few experimental runs.
In a pull system, production at each step is triggered by:
Answer: Downstream demand signals (kanban)
Pull systems use kanban signals from downstream operations to authorize upstream production only when replenishment is needed.
When a process has a Sigma level of 3, approximately what percentage of outputs fall within specification limits?
Answer: 93.32%
A 3-sigma process yields approximately 93.32% of outputs within spec, corresponding to about 66,807 defects per million opportunities.
Which analysis technique best helps a team understand the sequence in which events contributed to a process failure over time?
Answer: Timeline fault tree analysis
A timeline fault tree traces the chronological sequence of contributing events and conditions that combined to produce a failure.
A process team applies the Plan-Do-Check-Act (PDCA) cycle. During the 'Check' phase, which activity is most appropriate?
Answer: Comparing results against the original hypothesis
The Check phase involves measuring and analyzing results from the Do phase to determine whether the change produced the predicted improvement.
