SFC stands for Shop Floor Control and refers to which of the following?

• A. Online, real-time control and monitoring of machines on the shop floor, and analyzing machine activity to take corrective measures
• B. A cloud storage service
• C. A networking protocol
• D. A project management tool

Answer: (A)

The main idea here is real-time control and monitoring of equipment on the shop floor to manage and optimize production. Shop Floor Control tracks the status and activity of machines and work-in-progress as work orders move through the factory, and it analyzes this activity to make timely adjustments and keep production flowing smoothly.

This matches the described option because it explicitly talks about online, real-time control and monitoring of shop-floor machines and using that data to take corrective actions. That live, execution-level focus is what Shop Floor Control is all about—coordinating and controlling the execution of manufacturing tasks as they happen.

The other options miss that execution-focused aspect entirely: a cloud storage service is for storing data, not controlling or monitoring production in real time; a networking protocol defines how devices communicate, not how production is controlled on the floor; and a project management tool handles planning and tracking tasks, not the live management of machines and work orders on the shop floor.

In practice, SFC is a component of the broader Manufacturing Execution System family, providing visibility and control over the shop floor by dispatching operations, monitoring machine status, and enabling quick corrective actions to minimize downtime and optimize throughput.
