First, we constructed a framework to illustrate the variety of
purchasing strategies in supply relationships and networks.
Our framework combined the purchasing situation with the
complexity of relationship, which we used as a basis to derive
the vertical dimension of our framework. We established the
horizontal dimension in our framework on the goal of
purchasing, which emphasises either efficiency or
effectiveness of operation. As a result, we combined these
two dimensions in our conceptual framework to derive six
diverse purchasing strategies: price optimiser, adaptator,
bargainer, projector, clockwiser and updator.
