A customer asks for faster delivery. Sales says yes. Purchasing finds a new supplier. The warehouse takes a little extra stock to be on the safe side. Finance asks three months later why capital tied up in inventory is rising.
Everyone did their job. And yet the decision doesn't hold together.
This is exactly where supply chain management becomes relevant. Not as a fancy English term. Not just as a new system. But as the way you manage the connections between customers, products, suppliers, inventory, service and profitability.
For SMEs, supply chain management is rarely about large global models. It's more down to earth: How do you ensure the right products are available without tying up too much capital in inventory? How does sales make promises that operations can actually deliver on? How do you decide which customers, products and suppliers deserve the most attention?
If you don't manage it actively, complexity manages you.
