A project manager is made aware that there are defects in the parts provided by a supplior, which are causing delays in the testing phase. The supplier claims that all parts have been delivered as per the contract. If the defects are not fixed by the supplier within one week, the product release will be impacted. What should the project manager do? Request a cancellation of the procurement contract with the supplier and impose a penalty. Request a revision of the procurement contract to include specifications for the parts. Review the procurement contract and ask the supplier to negotiate a solution. Escalate this issue to senior management, as the supplier is not following the procurement contract
