Simple tree can be applied to the purchase of one-time without the presence of expectations the purchase again.

Identifying Potential Sources

The sources of Knowledge are important qualifications of various buyers. Sources can be searched by:

  • What is the motivation that in submitting the supplier needs in accordance with the expected buyers in the long term or short term?

Supplier Evaluation Methods

A method for evaluating the suppliers are divided into two:
  • Informal and Semi formal Evaluating and Rating. Informal evaluation includes estimate of internal and supplier from anywhere in the Organization of the buyer which the contacts take place. "How are things going with supplier X?" became the usual questions that can and should be asked by personnel supply when in contact with others in their organization.

Pareto analysis comparing the dollar volume for variables such as percent of suppliers, percent of supplies, and a number of orders, development strategies that focus on high-dollar purchases. Portfolio analysis typically include supply market risk in assessing and focused considerable attention on the ability of increasing value.
