In July 1991, a team within the Clinical Chemistry Department at Westmead Hospital used control charts and other statistical tools to analyze the supplies and inventory process. No single major problem was discovered. Instead, the team found many small problems causing delays and inefficiencies in the process. By developing and implementing multiple solutions, the team was able to streamline the process and reduce the number of principal suppliers.
The number of principal suppliers was reduced by two-thirds. The average number of "urgent" orders, which add extra steps to the purchasing process, was reduced by three-quarters. The mean turnaround time for common clinical chemistry laboratory tests improved by 8%.
1991年7月，韦斯特米德医院临床化学科的一个团队使用控制图和其他统计工具来分析供应和库存流程。未发现单一的重大问题。相反，该团队发现了许多导致流程延误和效率低下的小问题。通过制定和实施多种解决方案，该团队能够简化流程并减少主要供应商的数量。
主要供应商的数量减少了三分之二。增加采购流程额外步骤的“紧急”订单的平均数量减少了四分之三。常见临床化学实验室检测的平均周转时间提高了8%。
