Question 201 - CSCP discussion

The production scheduler for a bottleneck resource should ensure a constant queue of work waiting to be processed because:

Maximizing Utilization: The bottleneck resource is the most critical point in the production process. Keeping it constantly fed with work ensures it is utilized to its maximum capacity, thereby increasing overall throughput.

Minimizing Downtime: Ensuring a constant queue reduces idle time for the bottleneck resource, which is crucial for maintaining steady production flow and meeting output targets.

Theory of Constraints: According to the Theory of Constraints, the performance of the entire production system is limited by the bottleneck. By keeping a constant queue, the scheduler helps optimize the flow through the bottleneck, improving the efficiency of the entire system.

Production Stability: A constant queue helps maintain a stable production process, reducing variability and improving predictability in production schedules.

Scheduling additional preventive maintenance (Option A) is important but should not interfere with maintaining a constant queue. Increasing production lot sizes (Option C) can lead to inefficiencies and higher inventory costs. Implementing pull signals (Option D) may not directly address the need to keep the bottleneck resource continuously busy.
