We keep ours very simple. We have an initial risk assessment and an annual one based on various elements and how integrated/dependent we are on the vendor. We use the following:
1. Criticality
2. Dependence
3. Financial Commitment
4. Performance
5. Regulatory Impact
6. Business Impact
7. Supply Chain
We have just begun developing our vendor management program and are starting slow and we thought this was a good start. I would be interested in any feedback if anyone has any.
