Production lead time is not just one KPI among many. It is the result of almost everything that happens in a factory.
Productivity. Quality management. Maintenance. Multi-skilled employees. Setup-time reduction. Bottleneck management. Standardized work. Production lot sizes. Process synchronization. Accurate production sequencing. All these factors affect production lead time. And production lead time reflects how well all these factors work together.
A factory may track dozens of operational KPI. But if production lead time remains long, unstable, or unpredictable, the production system is not performing as it should.
That is why production lead time is such a powerful management indicator: it reveals the combined effect of the entire production system.
Toyota measures it closely. Many European manufacturers do not measure it at all. What you do not measure, you cannot manage.
