How are time, quality, flexibility, and cost traded off in the two different systems? |
|
Definition
Time (amount of automation, maximum output/capacity required, line balancing, bottlenecks, lead times), flexibility (volume flexibility vs. customization flexibility, automation and/or workforce capabilities - postponement), quality (consistency and high performance - training, automation, jidoka - everyone is responsible for quality), cost (inventory, defects, loss, damage, labor, facilities, packaging, product, service, support system) |
|
