Question 1

Which lean tool maps the flow of materials and information from supplier to customer to identify waste?

Accepted Answer

Value stream mapping

Answer

Value stream mapping (VSM) visually documents current-state material and information flows to identify non-value-adding activities and design a leaner future state.

Question 2

In Theory of Constraints (TOC), the 'constraint' or bottleneck is defined as:

Accepted Answer

The resource that limits the system's throughput

Answer

In TOC, the constraint is the weakest link — the resource whose capacity determines the maximum output of the entire system.

Question 3

What is the primary goal of Total Productive Maintenance (TPM)?

Accepted Answer

Maximizing equipment effectiveness through proactive, operator-led maintenance

Answer

TPM aims to eliminate equipment losses by involving operators in maintenance, preventing breakdowns, and continuously improving Overall Equipment Effectiveness (OEE).

Question 4

Overall Equipment Effectiveness (OEE) is calculated as the product of:

Accepted Answer

Availability, performance, and quality rates

Answer

OEE = Availability × Performance × Quality, capturing losses from downtime, speed reduction, and defects in a single metric.

Question 5

In quality management, 'statistical process control' (SPC) uses control charts to:

Accepted Answer

Distinguish between common-cause and special-cause variation in a process

Answer

SPC control charts plot process data over time with control limits to detect when a process shifts from normal (common-cause) variation to abnormal (special-cause) variation.
