John is the project manager for a large project in his organization. A new change request has been proposed that will affect several areas of the project. One area of the project change impact is on work that a vendor has already completed. The vendor is refusing to make the changes as they’ve already completed the project work they were contracted to do. What can John do in this instance?

When a vendor refuses to make changes after completing contracted work, the contract agreement serves as the binding document to resolve disputes and clarify obligations. Contractual Obligations: The agreement outlines the scope of work, responsibilities, and any clauses related to change management. Ensures both parties adhere to predefined terms. Steps to Resolve the Dispute: Review clauses about post-completion changes. Assess whether the requested changes fall within the vendor’s contractual obligations. Why Other Options Are Less Suitable: SLA: Typically focuses on performance and service quality, not contract modifications. RFP: Pre-contract document, not applicable for resolving disputes. Withholding Payments: A punitive action that could escalate the conflict without resolving the issue. EC-Council CISO Reference: Vendor Management: Emphasizes the importance of clear contracts for managing vendor relationships and resolving conflicts. Legal and Compliance Guidance: Stresses adherence to contractual terms to ensure fairness and enforceability.
