Question: Black Belts and Master Black Belts are often tasked with conducting a closed-loop assessment of a Six Sigma methodology or project. This type of formal evaluation is done to ensure that the methodology was followed correctly and to assess its results. The following are questions that are likely asked in this assessment EXCEPT:
  what are the project’s pro-forma projections?
  how accurate were the SWOT projections?
  how were challenged and difficulties assessed?
  what new opportunities developed from the methodology?

what are the project’s pro-forma projections?

Explanation: The following question is not asked in a closed-loop assessment: what are the project’s pro-forma projections? Black Belts and Master Black Belts conduct closed-loop assessments of Six Sigma methodologies to make sure that all aspects have been implemented. These assessments are also used to assess whether the methodologies had led to the desired outcomes. For example, an assessment would explore whether SWOT projections were accurate and what they may have missed in the risk analysis portion of a project.

Question: The Risk Priority Number (RPN) methodology is an analytic tool that is used to determine the risks associated with potential problems for a product or a process. The following are components of the RPN equation EXCEPT:
  Source
  Severity
  Occurrence
  Detection

Source

Explanation : The Risk Priority Number (RPN) methodology has the following components: severity, occurrence, and detection. An RPN is calculated using the following equation: RPN = Severity X Occurrence X Detection. The goal of an RPN is to evaluate the risk of problems showing up during product manufacturing or processes, and to prioritize the best way to deal with these risks.

Question: Janine is a senior financial manager who has ensured that the hospital in which she leads the finance department has all the resources necessary to implement Six Sigma methodologies. Janine is considered a:

Question: Design for Test is a design technique that offers a benefit of:

  manufacturability
  customer satisfaction tests
  defect diagnosis
  smaller process variation

Show or Reveal the Answer

defect diagnosis

Explanation : Design for test is a design technique that offers a benefit of defect diagnosis. Design for test, as a design technique, aims to introduce a testing capability in the manufacture of electronic. The goal of this technique is to introduce and validate the capability of diagnosing product defects. For example, a standard oven may have a function that provides a light warning to consumers that there is defect in the product.

Question: Drake International is compiling a list of their customers who have purchased large items in successive years. They complete a contingency table that compiles biographical information on the customers such as age and occupation along with information on the purchases. What are the values in a contingency table based on?
  Prior knowledge
  Empirical evidence
  Personal experiences
  Public data repository

Show or Reveal the Answer

Empirical evidence

Explanation : A contingency table contains values based on empirical evidence. A contingency table contains variables collected in order to be analyzed. For example, Drake International may be interested in how much money their male customers have spent in successive years and their respective occupations. A contingency table is a convenient and visually accessible manner to analyze variables that could affect business decisions such as marketing campaigns.

Question: An example of a planning diagram that shows an interdependence of tasks within a project is a(an):

  PDPC
  AND
  PERT
  CPM

Show or Reveal the Answer

AND

Explanation : An example of a planning diagram that shows an interdependence of tasks within a project is an Activity Network Diagram (AND). An Activity Network Diagram (AND) is a planning visual tool that shows an interdependence between tasks in a project. For example, a quality assurance individual cannot perform his work until the production manager signs off on the production cycle. The goal of an AND is to visually display to team members how their work affects and is affected by the roles and responsibilities of others in the team.
