Questions from this subtopic
Each one with the model answer underneath.
- 1
What is meant by lean production?
Model answer
An approach that aims to produce using the minimum of resources by systematically removing every activity that adds cost but no value for the customer.
- 2
Name four types of waste that lean production seeks to eliminate.
Model answer
Excess stock, waiting time, unnecessary movement of goods, and defective output that has to be reworked.
- 3
What is just in time production?
Model answer
A system in which materials and components arrive from suppliers exactly when they are needed, so almost no stock is held.
- 4
Give two conditions a business must satisfy before just in time can work.
Model answer
Suppliers must be reliable and close enough to deliver frequently and on time, and incoming quality must be high because there is no spare stock to replace a defective part.
- 5
What is kanban?
Model answer
A signalling system, traditionally a card, that tells the previous stage to produce or supply more only once the following stage has used what it holds.
- 6
Why is kanban described as a pull system?
Model answer
Production is triggered by actual demand from the following stage rather than by a forecast pushed down the line, so nothing is made until it is needed.
