What does the term 'voice of the customer' (VOC) mean in Six Sigma?
Answer: Systematically capturing customer needs, wants, and expectations
VOC is the process of capturing customer requirements to translate them into measurable Critical-to-Quality (CTQ) characteristics.
Critical-to-Quality (CTQ) characteristics are:
Answer: Product or process features that directly affect customer satisfaction and must be measured and controlled
CTQs translate VOC requirements into specific, measurable process parameters that drive customer satisfaction.
In Six Sigma, what is 'Y = f(X)' used to express?
Answer: The concept that process outputs (Y) are functions of process inputs and factors (X)
Y = f(X) expresses that outputs (quality, throughput) are determined by input variables and process factors, guiding root cause analysis.
What is a 'Green Belt' in Six Sigma?
Answer: A part-time Six Sigma practitioner who leads smaller improvement projects while working in their primary role
Green Belts are employees trained in Six Sigma methods who lead smaller-scope projects within their own work area.
What is the purpose of a SIPOC diagram in Six Sigma?
Answer: Provide a high-level view of a process by identifying Suppliers, Inputs, Process, Outputs, and Customers
A SIPOC diagram gives project teams a broad overview of the process scope and key stakeholders before detailed analysis.
Lean Six Sigma combines lean manufacturing and Six Sigma primarily to:
Answer: Eliminate waste while simultaneously reducing process variation and defects
Lean Six Sigma integrates lean's waste elimination tools with Six Sigma's statistical rigor to improve both speed and quality.
