日产使用Kraljic组合购买模型作为业绩指标。这个模型是由Peter Kraljic提出的，最早出现在1983年的《哈佛商业评论》上。无论其年龄大小，它都被认为是全球组织中使用的一种有用且流行的模型(Oliver, 2004)。日产使用这一性能矩阵的主要目的是通过在采购中启动最大功率来最大限度地提高供应的安全性和降低买方的成本。为了做到这一点，采购从交易活动变成了战略活动。关键的概念是采购必须成为供应的管理。在使用这个模型时，涉及到以下四个不同的步骤(Cooper, 2002)。采购分类，市场分析，战略定位，行动计划。

As a metrics of performance, Nissan used the Kraljic Model of Portfolio Purchasing. This model had been presented by Peter Kraljic, which first appeared in the year 1983 in the Harvard Business Review. Irrespective of its age, it has been identified as a useful and popular model used in organizations all across the globe (Oliver, 2004). The key purpose behind the utilization of this performance matrix at Nissan is for maximizing the security of supply and reducing the costs for the purchaser by the initiation of maximum power in purchases. In order to do so, procurement moves to be an activity of transaction to a strategic activity. The key notion is that purchasing must become the management of supply. In using this model, there is an involvement of four different steps that are as follows (Cooper, 2002).Classification of purchases、Analysis of market、Strategic positioning、Planning of action.
