Purchasing Policy and Procedure

Looking to revamp our corporate purchasing policies and procedures. We are a $1B + technology company. Any templates, strategies etc?

My organization (mid-size, healthcare administration) is also looking at our current procurement process. One of the best practices we are currently reviewing states that we should be minimizing the number of vendors used for a service / commodity is a good practice. However, doesn't that depend on what type of good / service it is?

- Also - how often should we be reviewing our preferred vendor lists?
