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.

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.

Deriving the supplier class

We assess quality, costs and punctuality along the complete procurement process, from the offer, supply and service phase until the product in practice phase. The appraisal logic therefore consists of three dimensions and phases, which are combined to result in nine appraisal criteria. 

Assess logic of dimensions and phases

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.
