Question: Michael’s team is conducting Enterprise Resource Planning (ERP) for the organization. After voicing disagreements on how to proceed in the initial phases, team members are now beginning to operate as a team not as a group of individuals. This stage in team growth is referred to as:
  norming
  adjourning
  performing
  forming

Show or Reveal the Answer

norming

Explanation : This stage in team growth is referred to as norming.

Norming is a stage in team growth and development whereby members begin to operate as a team not as a group of individuals. A strong team leader realizes that this stage can only occur after the earlier stages of disagreements have been resolved. Teams that do not reach norming in their growth risk poor performance.

Question: A relationship matrix matches process ________ and _________.
  managers; employees
  inputs; outputs
  divergences; convergences
  accelerators; decelerators

Show or Reveal the Answer

inputs; outputs

A relationship matrix matches process inputs and outputs.
Explanation : Relationship matrices are used to describe the connection between process inputs and desirable outputs. For example, if an application designer wishes to match available technological expertise to client needs (desirable outputs), a relationship matrix can be used. Teams gather input through brainstorming and other data collection methods in order to match inputs to desirable outputs in a project.

Question: A Black Belt practitioner is asked to facilitate a series of workshops in an organization. She notices that a few participants in the workshop are dominating the discussion. To provide leadership in this group setting, the practitioner must:
  end the workshop session early
  request that all speaking out of turn to leave
  give every person a chance to contribute
  separate the dominating participants from the group

Show or Reveal the Answer

give every person a chance to contribute

Explanation : To provide leadership in this group setting, the practitioner must give every person a chance to contribute.

Team facilitation techniques are an important toolset used by Six Sigma Black Belt practitioners. During group settings such as a workshop, a few people may dominate a discussion and it is the role of the practitioner to facilitate a discussion whereby everyone gets an opportunity to participate fully.

Question: Interest-based bargaining is an effective tool in conflict resolution because:
  it reduces interest rates for short-term loans
  it protects the interests of paying clients
  it maximizes the interests of banks
  it provides a solution that is in everybody’s interests

Show or Reveal the Answer

it provides a solution that is in everybody’s interests

Explanation : Interest-based bargaining is an effective tool in conflict resolution because it provides a solution that is in everybody’s interests.
Conflict resolution tools available to Black Belt practitioners must provide problem-solving outcomes. Interest-based bargaining is one such tool that structures problems and solutions in such a manner that all parties involved understand each other’s views. Once they have understood each other’s views, they can reach a resolution to the conflict that takes into account everybody’s interests.

Question: Within each production cycle of 20,000 chairs, there are two types of defects that can occur at the following rates: wrong dimensions (240 defects) and loose bolts (100 defects). If the defects can occur only once in each item, what is the Defects per Million Opportunities (DPMO) measurement of this process?
  3,400
  8,500
  5,800
  6,800

Show or Reveal the Answer

8,500

Explanation : The Defects per Million Opportunities (DPMO) are 8,500. The Defects per Million Opportunities is a process performance metric that calculates the potential defects that can occur per million opportunities. Opportunities are considered ways that a defect can occur. Since the defects can occur once in each production cycle, DPMO is calculated as such:

Total number of opportunities for defects = 20,000 + 20,000
= 40,000
DPMO = (#defects X 1,000,000) ÷ (total number of opportunities for defects)
= (340 X 1,000,000) ÷ (40,000)
= 8,500

Question: The Risk Priority Number (RPN) in an FMEA exercise is derived from
