Mudas in the conventional production system
Limits of the mass production system
Mass production systems, which generate many Mudas, do not meet current strategic needs of companies: quality, costs, delivery time.
It can easily be seen how Mudas are generated by the mass production system.
1. Muda of waiting: a waiting employee does not create added value.
2. Muda of transport: products transported from one place to another in the plant do not create any added value.
3. Muda of inventory: capital unnecessarily tied up, value destroyed.
4. Muda of processing: stress of the work.
5. Muda of motion: no value is created during motion.
Other additional costs linked to the mass production system
6. Example of a single-product line: non-flexible heavy investment, inability to meet large variations in demand rapidly and productively. This kind of mass production system suffers from sudden fluctuations in market demand rather than absorbing them.
7. Example of a single-product line under-used through lack of demand: heavy investment under-used: poor return on investment.
