OPM 2203 (Lean) Lesson 03 Quiz for Lesson 02

Which of the following wastes refers to excess movement by workers that does not add value to the product?

• Overprocessing

• Motion

• Inventory

• Defects

What type of waste occurs when parts or employees are idle, waiting for work to be completed?

• Waiting

• Transportation

• Defects

• Overproduction

Which waste is caused by producing more items than needed or too early in advance?

• Motion

• Overproduction

• Defects

• Overprocessing

The waste of inventory primarily refers to:

• Products shipped before customer orders are confirmed.

• Unnecessary accumulation of raw materials, work-in-progress (WIP), or finished goods.

• A slow machine causing downtime.

• Having to move materials between different workstations.

Overprocessing waste can be described as:

• Moving a product back and forth across multiple stations.

• Performing tasks or steps that add no value from the customer’s perspective.

• Delays in production caused by broken machinery.

• Creating more products than the customer demands.

Which of the following best illustrates transportation waste?

• Moving components multiple times within the factory unnecessarily.

• Workers having to wait for machines to be serviced.

• Parts that do not meet quality standards.

• Producing additional units to meet future demand.

A product defect waste refers to:

• Extra inspections added to the process to ensure quality.

• Any product that fails to meet customer requirements.

• Storing excess products beyond the needed levels.

• Waiting for material delivery.

Which of the following statements is NOT a way to eliminate waste?

• Produce only what is needed based on customer demand.

• Train workers to perform redundant inspections to ensure quality.

• Arrange equipment to minimize unnecessary movements.

• Reduce idle time by balancing workloads.

Why is reducing large inventories considered a good lean practice?

• It increases lead time and buffers problems.

• It prevents waste from being hidden within the system.

• It allows more time for machine maintenance.

• It ensures maximum resource utilization.

Which acronym is often used to represent the seven types of waste in lean manufacturing?

• MUDAS

• LEANX

• TIMWOOD

• SIXSIG
