"" Management, after reviewing the certification, authorizes the software or system to be implemented in a production status, in a specific environment, for a specific period. There are two types of accreditation: provisional and full. Provisional accreditation is for a specific period and outlines required changes to the applications, system, or accreditation documentation. Full accreditation implies that no changes are required for making the accreditation decision. Note that management may choose to accredit a system that has failed certification or may refuse to accredit a system even if it has been certified correct. Certification and accreditation are related, but they are not simply two steps in a single process. ""
