Lean Production and Quality Management Quiz

Define lean production.

• A system that focuses solely on mass production.

• A philosophy that emphasizes reducing waste and achieving greater efficiency.

• A method for maximizing profits by increasing prices.

• A process that relies only on automation.

Which of the following is NOT one of the seven sources of waste (muda) in lean production?

• Defective products.

• Overproduction.

• Unnecessary transportation.

• Underutilization of workers.

Define efficiency in lean production.

• Increasing input use regardless of cost.

• Using resources more productively to generate more output cost-effectively.

• Focusing solely on reducing labor costs.

• Maximizing output without regard to quality.

Define continuous improvement (kaizen).

• Making infrequent, radical changes to processes.

• Implementing small, incremental changes continuously to improve productivity.

• Outsourcing production to reduce costs.

• Eliminating all quality checks to speed up production.

Which is an advantage of kaizen?

• It reduces production costs instantly with minimal effort.

• It empowers employees to contribute ideas that reduce errors and enhance efficiency over time.

• It requires no investment in staff training.

• It guarantees zero defects from day one.

Which is a disadvantage of kaizen?

• It eliminates the need for skilled labor.

• It can be costly and time-consuming to implement, sometimes increasing workloads.

• It immediately improves productivity without any drawbacks.

• It requires no employee involvement.

Define just in time (JIT).

• An inventory system that maintains large safety stocks.

• An inventory management system where stocks are delivered exactly when needed.

• A method that delays deliveries to reduce costs.

• A system that always keeps extra inventory on hand.

Which risk is associated with JIT?

• Excessive inventory holding costs.

• Stock shortages if deliveries are delayed.

• Overproduction due to large buffer stocks.

• Increased waste from surplus production.

Define cradle-to-cradle (C2C) design and manufacturing.

• A production model that focuses on disposable products.

• A sustainable model that designs products for continuous recycling with zero waste.

• A method that increases waste for cost savings.

• A system that ignores environmental impacts.

Which feature is characteristic of C2C design?

• Materials are designed to be non-recyclable.

• All material inputs are either technical (recyclable) or biological (compostable).

• Products are intended for single use only.

• It emphasizes cost reduction over sustainability.
