Key ideas in Supply Chains in the Real World
- A workflow's total finished output is strictly capped by its slowest station, the bottleneck
- Speeding up any step before the bottleneck only creates piles of unworked inventory waiting in front of it
- The oven can still only finish 20 croissants per hour, so finished output remains 20 per hour
- Queue length predictably equals how fast new items or customers arrive multiplied by how long each one takes to process
- Persistent long queues point to structural system design issues, not random flukes
- If orders arrive faster than the slowest step can clear them, a line grows inevitably
- Sealing takes 5 minutes per kit, making it the bottleneck that limits every other station
- Only increasing capacity at the constraint step raises total system throughput
- Adding labor or equipment to a non-bottleneck step increases operating costs without yielding a single extra completed unit
- A buffer is a small cushion of work placed immediately in front of the bottleneck
- Because any idle minute at the bottleneck is an hour lost forever across the whole system, the buffer protects it from upstream interruptions
- Buffers belong before the constraint, not piled up at the end after it
- Visual boards and ticket rails reveal where work accumulates before delays reach the paying customer
- The station with a physical buildup of tickets, bins, or cards right in front of it is the active bottleneck
- An empty station immediately downstream from a large pileup indicates work is starved by an upstream constraint
- Shipping in bulk across oceans or highways is efficient because thousands of items move together to a single point
