Which of the following BEST describes 'scope creep' in a Six Sigma project?

A team translates VOC data into specific, measurable product or service requirements. This translation process results in which output?
Answer: CTQ (Critical to Quality) characteristics
The VOC translation process converts customer language and needs into specific, measurable CTQ characteristics that can be tracked and improved.
In the Define phase, the team identifies the process start and end points. These boundaries are known as what?
Answer: Project scope boundaries (start and stop)
Defining the process start and stop points establishes the project scope, clarifying which steps are included in the improvement effort.
Which statement about a SMART goal statement in a project charter is CORRECT?
Answer: It must be Specific, Measurable, Achievable, Relevant, and Time-bound
A SMART goal statement ensures the project has a clear, quantifiable target with a defined timeline, making success objectively measurable.
During Define, a Green Belt identifies that a process has multiple customers with conflicting needs. What is the BEST approach?
Answer: Prioritize CTQs by customer segment and discuss trade-offs with the champion
When customers have conflicting needs, the team should segment CTQs by customer group and work with the champion to prioritize based on business strategy.
What is the MAIN difference between a 'problem statement' and a 'goal statement' in the project charter?
Answer: The problem statement describes the current gap; the goal statement quantifies the desired improvement
The problem statement describes the current undesirable condition, while the goal statement specifies the measurable target the team is working toward.
