Previous OM in the News posts have discussed shortages of semiconductor chips caused by the leaning of supply chains. Supply chain disruptions of even a few days can lead to shortages if companies run too lean. During the pandemic, planning for supply chain disruptions has assumed increasing urgency.
Murata Manufacturing supplies about 40% of the world’s multilayer ceramic capacitors. MLCCs are used in everything from smartphones, appliances, cars, to data centers. The company closed its Fukui plant for the last week of August 2021 due to a COVID-19 outbreak among workers.
The plant closure caused less serious disruption to the company, because Murata had inventories on hand to meet customer demand. The company was also able to respond quickly and implement additional prevention measures, resuming production within a few days.
