Batch production enables sooner identification of the quality problem than one piece flow.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Batch production does not enable sooner identification of quality problems compared to one piece flow. In batch production, products are produced in large quantities before moving to the next step, which means that any quality issues may not be discovered until the entire batch is complete. On the other hand, one piece flow involves producing one product at a time, allowing for immediate identification and resolution of any quality problems that may arise. Therefore, the statement is false.

Connection between 2 processes with comparable cycle times is best by
- A.
  
  Supermarket
- B.
  
  FIFO
- C.
  
  One Piece Flow
- D.
  
  Inventory
Correct Answer
C. One Piece Flow

Explanation
One Piece Flow is the best method for connecting two processes with comparable cycle times because it allows for a continuous flow of work between the processes. With One Piece Flow, each unit of work moves directly from one process to the next without any waiting or inventory buildup. This minimizes lead time, reduces waste, and improves overall efficiency. By contrast, the Supermarket method involves storing inventory between the processes, which can lead to delays and excess inventory. FIFO (First In, First Out) is a method of organizing inventory, but it does not directly address the connection between processes.
