Herbie (the bottleneck analogy)

Herbie is a helpful analogy for understanding bottlenecks, where a narrow section in a process limits the overall flow. Think of a highway with multiple lanes merging into a single lane; traffic can only move as fast as the tightest spot. In business or systems, a bottleneck is the stage with the least capacity that slows down the entire process. Identifying and improving this constraint—like widening the lane—helps increase overall efficiency and throughput, ensuring smoother, faster operations without unnecessary delays.
