Supplier appraisal - transparency from A to Z

Article: Supplier appraisal - transparency from A to Z

Comparison creates confidence.

We assess our suppliers according to transparent criteria along the procurement process. Here we differentiate according to different supplier classes, performance dimensions and phases which lead to a final rating.

Comparison between "target" and "actual"

The variance comparison assesses provided supplies and services with regard to the contractually stipulated agreements; the appraisal process looks at qualified suppliers within a product group.

Classification in supplier classes

The appraisal process allocates the suppliers to classes. The scope of the appraisal varies according to the supplier class:

  • high (high appraisal intensity and frequency)
  • middle (middle appraisal intensity and frequency)
  • low (low appraisal intensity and frequency)

The supplier class that your company is allocated to depends on the requirement category of your DB-relevant supplies and services, and on their strategic significance.

Appraisal result: the rating

The supplier appraisal results in a rating on the following levels:

  • outstanding, i.e. the supplier was above the requirements of the DB AG
  • good, i.e. the supplier met the requirements of the DB AG
  • restricted, i.e. the supplier was partly consistent with the requirements of DB AG
  • poor, i.e. the supplier did not meet the requirements of the DB AG

The supplier is informed of the appraisal results at least once a year.
