The average of per cent of the expediting cost of case companies was lower than that of the survey respondent companies. It was partly because in one survey respondent company No. 12, the per cent of expediting cost was high (18.1 per cent). The average is less interesting than the high variability from company to company. This illustrates the risk involved in overseas sourcing that can significantly impact costs. If expediting is required, then it is likely to be costly.
