SIX SIGMA BLACK BELT EXAM
QUESTIONS WITH 100% VERIFIED
CORRECT ANSWERS!!
SWOT is an acronym for:
strengths, weaknesses, opportunities, threats
In a series of linked processes and associated feedback loops the product or service flows
________ and the information flows ___
downstream, upstream
A team has been asked to reduce the cycle time for a process. The team decides to collect
baseline data. It will do this by:
obtaining accurate cycle times for the process as it currently runs
Customer segmentation refers to
grouping customers by one or more criteria
A project activity not on the critical path has required 20% longer than the time originally
allocated. The project team should
study the effect this will have on other activities because the project may still be on schedule
A quality engineer employed by a hospital is asked to improve the process of medication
storage in locked cabinets near patient doors. One defect that occurs rarely is that the
medication caddy is left out when the cabinet is relocked. The engineer installs a gravity
activated arm that will not permit the door to close when the caddy isn't inside. This
improvement is best described by which approach to problem solving?
Poka yoke
The operators of a manufacturing cell work out a more orderly arrangement for tool
storage and establish a schedule to maintain cleanliness on a daily basis. These
improvements are best described by which approach to problem solving?
, 5S
A team's goal is to improve information flow in a payroll function. They make thirty-three
Post-It® notes, each listing an issue for further investigation. After some discussion, they
group them into four categories: mandated record keeping, privacy concerns, insurance
concerns and transfer concerns. This grouping process is best described by which approach
to problem solving?
Affinity diagram
The primary metric for a project is reduced cost for process A . Baseline data might
include
current maintenance costs
The term "expected value" is closest to the term
mean
If the probability that event A occurs is .51, the probability that event B occurs is .64 and
events A and B are statistically independent then:
the probability that both A and B occur is 0.3264
The median is a better choice than the mean for a measure of central tendency if the data
often has outliers
A team wants a technique for determining and displaying priorities based on frequency of
various defect types. They should use
Pareto chart
A team wants a technique for improving consistency of assembly operations. They should
use
written and diagrammed work instructions
Samples of size n=36 are randomly selected from a population with mean = 125 and
variance 12. Find the variance of the distribution of sample means.
