The recipient should have knowledge of the systems and procedures implemented at the supplier for the generation of the CoA. Arrangements should be in place to ensure that significant changes to systems are notified and the effectiveness of these arrangements should be subjected to periodic review.

接受者应了解供应商为生成CoA所实施的系统和程序。应做出安排，确保系统的重大变化得到通知，并对这些安排的有效性进行定期审查。

Data related to activities which are outsourced are routinely provided as summary data in a report format (e.g. CoA). These summary documents are reviewed on a routine basis by the contract acceptor and therefore the review of data integrity at the contract acceptor site on a regular periodic basis (e.g. during on-site audit) takes on even greater significance, in order to build and maintain confidence in the summary data provided.

与外包活动有关的数据通常以报告格式（如CoA）提供摘要数据。这些摘要文件由合同接受方进行例行审查，因此在合同接受方现场定期审查数据的完整性（例如在现场审计期间）具有更大的意义，以便建立和保持对所提供的摘要数据的信心。
