Suppose that you work for a large financial institution. The time has come to upgrade the software used in all of your branches. For the past 30 days, four high-volume branch locations have been using software from four possible vendors on a trial basis. You have been collecting data from each branch to determine which software package yields the best performance. The best tool you can use to compare all of the data in one illustration is the:

  Box and whisker plot
  Affinity diagram
  Prioritization matrix
  Radar chart

Radar chart

Managers at a food manufacturing plant are studying the efficiency of sorting processes. They believe that 2% of food products contain defects; to prove this, their stated alternate hypothesis (H1) is that:

  Not enough information is available
  2% of food products contain defects
  2% of food products do not contain defects
  98% of food products do not contain defects

Show or Reveal the Answer

2% of food products do not contain defects

Explanation : In this research, the alternate hypothesis (H1) states that 2% of food products do not contain defects.

The alternate hypothesis in a research study is the opposite of the null hypothesis and challenges the status quo. In the above food manufacturing plant, the alternate hypothesis (H1) is that 2% of food products do not contain defects.

In a Process Decision Program Chart (PDPC), a team leader can break down project components into elements. Each project element is then broken down into _______ and ________.

A.) debits; credits
B.) problems; countermeasures
C.) losses; profits
D.) internal pressures; external pressures

Show or Reveal the Answer

problems; countermeasures

Explanation : Each project element is broken down into problems and countermeasures.

Process Decision Program Charts (PDPC) are planning tools that use a decision tree to expand on problems and countermeasures for each project element. For example, if a fundraising event is scheduled to raise money for charity, potential problems in finding venues are accessibility and parking. A PDPC helps team members visualize potential problems and their countermeasures.

For a set of data, the average squared deviation from the mean, with a denominator of n-1.

A.) Sample

Which of the following is the order of evolution for most teams?

  Forming, Norming, Storming, Performing
  Storming, Norming, Forming, Performing
  Forming, Storming, Norming, Performing
  Performing, Storming, Norming, Forming

Show or Reveal the Answer

Forming, Storming, Norming, Performing

When working with attribute charts, which of the following values must you know in order to determine the upper and lower control limits?

  Standard deviation

In Design of Experiments, which of the following steps should you complete before you select your variables?

  Analyze data
  Define objective(s)
  Assign levels to the variables
  Conduct experiments

The Quincunx demonstration revealed which of the following points?

  You can't judge the process by sampling a part every so often.
  The more you adjust a process to nominal (e.g., the center), the more variation you will create.
  A process is probably void of undue influence of the six Ms if the process is bell-shaped.
  All of the above.

Show or Reveal the Answer

All of the above.

Which of the following is NOT a major type of resistance?

  Cultural
  Electoral
  Political
  Technical

Show or Reveal the Answer

Electoral

Which of the following descriptive statistic uses (σ) for a population and (s) for a sample?

  mean
  median
  standard deviation
  slope

Show or Reveal the Answer

standard deviation

Explanation : Standard deviation uses (σ) for a population and (s) for a sample.
Standard deviation is a descriptive statistic that takes into account how each data point deviates from the average of a data set. Standard deviation is an important measure of data scatter around a mean which is also an important aspect of a process’ variation. In Six Sigma methodology, the best way to reduce the inefficiencies of a process is to reduce its variation.

Which of the following Six Sigma tools illustrates the dynamic impact of customer needs on customer satisfaction?

  Pareto chart
  Affinity diagram
  Kano model
  PERT

Show or Reveal the Answer

Kano model

Which of the following is a reason to conduct your trials randomly?

  Less cost
  Creates bias
  Overcomes noise
  All of the above

Show or Reveal the Answer

Overcomes noise

  I,II,V,VI,VII,VIII
  I,III,IV,V,VI,VII
  I,II,IV,V,VI,VII
  All of the five Ms and one P are not represented by the choices

Show or Reveal the Answer

  Assumes things to be equal
  It is your theory
  It is what you would expect by chance alone

Which of the following is a benefit of a kaizen event?

  Fewer employees
  Reduced machinery
  Reduced takt time
  Increased employee involvement

Show or Reveal the Answer

Increased employee involvement

Explanation: Kaizen involves every employee in process of change - mostly in small, incremental changes. It focuses on identifying problems at their own source, solving them at their own source, and changing standards to ensure the problem stays solved forever. By involving employees they start looking about change at their environment to bring up results in there work area. And improved morale as employee begin to find work more enjoyable and easier.
