How parts departments are learning from the parts shortage?

It doesn’t matter where you sit in the aftermarket these days, parts are getting increasingly difficult to obtain — some parts more than others. None of the vendors give any reason to think there’s light at the end of the tunnel. Companies are struggling up and down the heavy-duty truck parts. A positive is parts providers are learning along the way — whether it’s improving communication within the company and with suppliers, having more “safety stock” on hand, or having various suppliers compete between themselves for the parts provider’s business. The lessons learned throughout the pandemic will help their businesses in the future as well.
It’s a nightmare right now. The future does not look bright regarding supply issues.
