Claims administration is one of the tools and techniques for the PMI process to control procurements. Claims, disputes, or appeals are made when the buyer and seller disagree about requested changes. Claims administration is described in section 18.104.22.168 of the PMBOK, 5th edition. Settlement by negotiation is preferred, followed by alternative dispute resolution (ADR) specified by contract, the need for legal resolution is not desirable. The process for settling claims should be defined before any project disagreements occur.
