What does 'takt time' represent in Lean methodology?
Answer: The rate at which a product must be completed to meet customer demand
Takt time is calculated by dividing available production time by customer demand. It sets the production rhythm needed to meet customer requirements without overproducing or underproducing.
Which of the following best describes the purpose of a Value Stream Map (VSM)?
Answer: To document the flow of materials and information required to deliver a product or service to the customer
A Value Stream Map visually depicts every step in the flow of materials and information, helping teams identify value-added versus non-value-added activities and prioritize improvement efforts.
In the 5S Lean framework, what does the third 'S' — 'Shine' — require teams to do?
Answer: Clean the work area and inspect equipment during the cleaning process
'Shine' (Seiso) goes beyond basic cleaning — teams clean the workspace while simultaneously inspecting equipment for defects, leaks, or abnormalities, turning cleaning into a form of inspection.
Which Lean concept refers to designing a process or device so that mistakes are physically impossible or immediately obvious?
Answer: Poka-Yoke
Poka-Yoke (mistake-proofing) involves design mechanisms that prevent errors from occurring or make defects instantly detectable before they move to the next step, reducing reliance on operator vigilance.
In Lean, 'Mura' refers to which type of process problem?
Answer: Unevenness or inconsistency in workflow and production levels
Mura means unevenness or variability in the flow of work. When production levels fluctuate unpredictably, it creates both idle time and overburden, leading to additional waste throughout the system.
Which Lean principle states that production should be triggered by actual customer demand rather than forecasts or schedules pushed from upstream?
Answer: Pull
The 'Pull' principle means that work is initiated only when a downstream process or customer signals a need, preventing overproduction and aligning output directly with real demand rather than predicted demand.
