Disrupted supply
DT is a UK-based business manufacturing circuit boards which it sells to other businesses. All of DT’s output is exported to Europe. The components that DT uses are sourced in the UK.
The supplier of a vital component closed suddenly in early 2020 disrupting DT’s supply chain. DT’s usual pattern of inventory control for this component is shown in Figure 1.
DT was forced to buy this component from a new and more expensive supplier.
DT stated: ‘We had no contingency plan. It was impossible for us to find alternative supplies quickly enough to fulfil all our existing orders. The new supplies had higher levels of defects.’
