A prospective seller, Seller XYZ, calls you to discuss the pricing contained in the response her company had previously provided to you. In addition to being a large customer of your company, Seller XYZ has also been a dependable, long-time supplier to your company. You would really like to see them win the business for your project. As the Project’s Procurement Manager, you have visibility into all of the pricing provided by other prospective sellers. During your discussions, Seller XYZ asks you for “guidance” on her company’s pricing so that they can be competitive with the other prospective sellers. How do you respond to Seller XYZ? Explain your thought process in deciding how to respond and, if appropriate, reference one or more relevant codes of ethics that may apply to this situation.
