In production systems, what is a bottleneck and how does it affect throughput?

• A. A measurement unit used for inventory valuation.
• B. A constraint that limits system throughput, causing delays and reducing overall production capacity.
• C. A type of storage rack.
• D. A method for scheduling maintenance.

Answer: (B)

The main idea here is a bottleneck—a part of the production process that slows down the whole system. In a line of work where each step must finish before the next can start, the fastest flow is still limited by the slowest step. That slowest operation sets the maximum rate at which finished goods can emerge because work piles up before it and the subsequent steps sit waiting for it to finish. Because of this, throughput—the number of units completed per hour—is governed by the bottleneck's capacity. If you want to raise throughput, you focus on increasing the bottleneck’s capacity, balancing the workflow, or removing inefficiencies at that stage. The other options don’t capture this rate-limiting effect. A measurement unit used for inventory valuation is about accounting for stock value, not production speed. A storage rack is simply space to hold items, not a factor that limits how fast you can produce. A method for scheduling maintenance is about planning downtime, which can affect availability but doesn’t define the inherent pace at which the system can process work.
