Lead time reduction means shortening not only working time but also all required time such as waiting time, inspection, and logistics.
Customer lead time refers to the time from receiving order to delivery, and manufacturing lead time refers to the time required from shipping material from a warehouse to storing finished product in a warehouse.
By lead time reduction, you can differentiate from competitors and expect a management effect.
Solve these issues
with lead time reduction in a factory
for lead time reduction
Streamlining the flows of information and materials enables the lead time reduction.
Stagnation (stagnation of work-in-process inventory) increases lead time, and extra inventory will occur.
Heijunka production makes products ordered from customers by averaging the types and quantities.
In a state where the flows of information and materials confuse, stagnate, or return, it creates excess work-in-process inventory and increases lead time, and reduces productivity.
First, we will create the “Material and information flow chart” from receiving order to shipment, analyze the current situation, and build processes that eliminate stagnation and waste.
There are many stagnation in a factory, such as waiting for transportation, delivery/shipping, warehousing, processing, assembly, and inspection etc.
Stagnation means “keeping and storing materials”, so it means that the materials exist as inventory.
Stagnation will increase lead time and will produce excess inventory.
Heijunka production (One piece flow production)
In case of line production, it seems that lot production in batches can produce faster than Heijunka production, which requires more changeovers. However, when considering the flow from receiving order to production and to shipment, the Heijunka production to average the types and quantities no matter what product is ordered by the customer, is able to ship faster.
The productivity will be low at the beginning when switching from lot production to Heijunka production, but if the skill of operators improved, the lead time will be significantly reduced.
