Step zero: Process SetupThe supply manager defines competencies (criteria) to be evaluated for selected suppliers, persons, services etc.
Step one: Inputs InitiationThe evaluating persons are asked to carry out their evaluations.
Step three: Average CalculationResulting average evaluations are generated on the basis of data gathered in step two. These average evaluations can then be used to rank suppliers for various business purposes (e.g.selecting a supplier for an individual order/contract or negotiations with suppliers). The evaluation cycle can be repeated using corrective adjustments (changing criteria, periods, weighting the inputs).
In essence, step three is an objective processing of the potentially rather subjective information obtained from individual evaluating persons (and combining it with data gathered from incoming goods). Evidently, the more information is collected from different evaluators, the more objective the resulting evaluation will be.
