A call center project's primary output (Y) is defined as 'average call handle time.' Which of the following would be most appropriately classified as an X (a process input/variable) affecting this Y, rather than as a Y (output) itself?
AAgent script adherence rate and system response time during calls.
BNumber of complaints escalated to management each month.
COverall customer satisfaction survey composite score.
DAverage call handle time reported as a weekly KPI.
Show answer & explanation
A is correct. In the Y=f(X) framework, the Y is the output of interest (here, average call handle time), while the X's are the inputs or process variables believed to influence that output. Agent script adherence and system response time are operational inputs that could plausibly cause changes in handle time, whereas satisfaction scores and escalation counts are themselves separate outputs, not inputs.

Within a Lean Six Sigma project charter, which section is specifically intended to justify why the organization should commit resources to the project by linking it to strategic or financial priorities?
AProblem Statement
BProject Scope
CBusiness Case
DProject Metrics
Show answer & explanation
C is correct. The business case is the charter element that connects a project to organizational goals, expected financial or strategic benefit, and urgency, giving sponsors a reason to approve resources. Problem statements, scope, and metrics all support the charter but serve different, more narrowly defined purposes.

When identifying customers during the Voice of the Customer step of Define, which of the following correctly distinguishes the two broad categories of customers a Green Belt should consider?
APromoters and detractors, categories derived strictly from Net Promoter Score results collected during the Improve phase.
BVoice of the Customer and Voice of the Process, representing customer opinions and statistical process-control data respectively.
CExternal customers, who receive or purchase the final product/service, and internal customers, who receive process outputs from within the organization before the final output reaches the market.
DPrimary and secondary customers, defined solely by which one generates the larger share of company revenue.
Show answer & explanation
C is correct. VOC identification requires looking beyond the paying end-customer to also capture internal customers — the next process, department, or role that receives an output within the organization. Missing internal customers is a common gap that leads to incomplete CTQ translation later.
