Push based supply chains are demand driven rather than forecast driven.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Push-based supply chains are forecast driven, meaning that they rely on predictions and estimates of demand to determine production and inventory levels. In contrast, pull-based supply chains are demand driven, where production and inventory are determined based on actual customer demand. Therefore, the given statement is false as push-based supply chains are not demand driven.Rate this question:

The seven wastes, as outlined in the Lean Manufacturing are
- A.
Over Production, Waiting, Transport, Manpower, Over Processing, Motion, Overtime
- B.
Over Production, Waiting, Transport, Inventory, Over Processing, Motion, Defects
- C.
Over Production, Waiting, Transport, Inventory, Scrap, Rework, Defects
- D.
All of the above
Correct Answer
B. Over Production, Waiting, Transport, Inventory, Over Processing, Motion, DefectsExplanation
The correct answer is "Over Production, Waiting, Transport, Inventory, Over Processing, Motion, Defects". This answer aligns with the seven wastes identified in Lean Manufacturing. Overproduction refers to producing more than what is needed, waiting refers to idle time, transport refers to unnecessary movement of materials, inventory refers to excess stock, overprocessing refers to unnecessary steps in the production process, motion refers to unnecessary movement of workers, and defects refer to products that do not meet quality standards.Rate this question:

A lean tool to map time taken for each process step and identify value and non value added steps
- B.
A basic flow chart tool that maps inputs, processes and outputs
- C.
A tool that analyzes the forces supporting or resisting a particular change
- D.
Used to create a workplace suited for visual control and lean practices
Correct Answer
A. A lean tool to map time taken for each process step and identify value and non value added stepsExplanation
Time value mapping is a lean tool used to analyze and map the time taken for each process step in order to identify value-added and non-value-added steps. By identifying non-value-added steps, organizations can eliminate or reduce them, leading to increased efficiency and productivity. This tool helps in streamlining processes and improving overall operational performance.Rate this question:

The main principles of Lean are (Check all that apply)
- A.
Identification of value
- B.
Elimination of waste
- C.
Generation of flow
- D.
MRP
Correct Answer(s)
A. Identification of value
B. Elimination of waste
C. Generation of flowExplanation
The main principles of Lean are the identification of value, elimination of waste, and generation of flow. These principles focus on maximizing efficiency and reducing unnecessary steps or processes in order to deliver value to the customer. By identifying what the customer truly values, eliminating any activities that do not contribute to that value, and creating a smooth flow of work, Lean aims to improve productivity and customer satisfaction. MRP, or Material Requirements Planning, is not a principle of Lean and is therefore not included in the correct answer.Rate this question:

Implementing 'Kanban' system can be effective method for
- A.
Creating Kanban cards to signal the need to move materials in a facility
- B.
Manage Inventory, create flow and eliminate wastes
- C.
Implementing lean, reducing excessive movement and transport
- D.
Implementing pull systems, reducing inventory and lead time
Correct Answer
D. Implementing pull systems, reducing inventory and lead timeExplanation
The Kanban system is a method used to implement pull systems, which means that materials are only produced or moved when there is a demand for them. This helps in reducing inventory and lead time because materials are not being produced or moved unnecessarily. Kanban cards are used to signal the need to move materials in a facility, which helps in managing inventory and creating flow. By implementing the Kanban system, a company can eliminate wastes and reduce excessive movement and transport, thus making the process more efficient.Rate this question:

Which of the following is not a goal of lean?
- A.
Reducing set-up times
- B.
Utilizing activity-based costing
- C.
Increasing machine utilization
- D.
Producing smaller lot sizes
Correct Answer
C. Increasing machine utilizationExplanation
Increasing machine utilization is not a goal of lean because lean focuses on eliminating waste and improving efficiency. While increasing machine utilization may seem like a way to improve efficiency, it can actually lead to overproduction and unnecessary inventory. Lean principles encourage balancing workloads, reducing downtime, and optimizing processes to ensure that machines are used effectively and efficiently, but not at the expense of creating excess inventory or overburdening the system.Rate this question:

Products with low demand should be:
- A.
Produced in the quantity needed
- B.
Batch processed and held in stock until needed
- C.
Assigned higher cost per unit
- D.
Discontinued or purchased from another supplier
Correct Answer
A. Produced in the quantity neededExplanation
Products with low demand should be produced in the quantity needed because producing them in large quantities would lead to excess inventory and potential wastage. By producing only the required quantity, the company can minimize costs and avoid tying up capital in inventory that may not be sold. This approach also allows for better flexibility in responding to changes in demand and reduces the risk of obsolescence.Rate this question:

Using kanban, production demand is triggered by:
- A.
The production planner
- B.
Forecast
- C.
Removal of product by the downstream customer
- D.
Any of the above
Correct Answer
C. Removal of product by the downstream customerExplanation
In kanban, production demand is triggered by the removal of product by the downstream customer. This means that when the customer takes a product from the inventory, it signals the need for more production to replenish the stock. This approach ensures that production is driven by actual customer demand, preventing overproduction and reducing waste. The production planner and forecast may also play a role in determining the quantity to be produced, but the actual trigger for production is the removal of product by the downstream customer.Rate this question:
