Question 1

'Kanban' in a lean system is primarily used to:

Accepted Answer

Signal the need to produce or replenish items based on actual consumption — a pull signal

Answer

Kanban is a visual signaling system that triggers production or replenishment only when needed, supporting a pull-based flow that reduces overproduction and inventory.

Question 2

'Single-piece flow' (one-piece flow) is preferred in lean because:

Accepted Answer

It reduces lead time, exposes problems immediately, and improves quality by processing items one at a time

Answer

Single-piece flow minimizes work-in-process inventory, reduces lead time, and surfaces quality problems immediately since defects can't hide in large batches.

Question 3

Overall Equipment Effectiveness (OEE) is calculated from which three factors?

Accepted Answer

Availability, Performance, and Quality

Answer

OEE = Availability × Performance × Quality, providing a comprehensive measure of how effectively manufacturing equipment is being utilized.

Question 4

'Standard work' in lean refers to:

Accepted Answer

Documented, repeatable procedures that define the current best way to perform a task, used as the baseline for improvement

Answer

Standard work captures the optimal sequence, timing, and method for each operation, creating a stable baseline that ensures consistency and provides a foundation for kaizen.

Question 5

In lean, a 'pull system' means:

Accepted Answer

Downstream processes signal upstream processes to produce only what is needed, when it is needed

Answer

A pull system produces items only in response to actual demand signals from downstream processes or customers, preventing overproduction and excess inventory.
