D.配置审核组完成物理配置审核,检查程序与文档的一致性、文档与文档的一致性、交付的产品与合同要求的一致性及符合有关标准的情况

答案

参考答案:C

解析:

在信息系统建设验收阶段,通常需要同时进行验收测试和配置审核,这是验收评审前必须完成的两项主要检查工作,由验收委员会主持。

测试组在认真审核需求规格说明、确认测试和系统测试的计划与分析结论的基础上制定验收测试计划。制定需测试的测试项,制定测试策略及验收通过准则。然后根据计划进行验收测试,根据验收通过准则分析测试结果,做出验收是否通过的决定,给出测试评价。根据测试结果编制缺陷报告和验收测试报告。

配置审核组完成物理配置审核,检查程序与文档的一致性、文档与文档的一致性、交付的产品与合同要求的一致性及符合有关标准的情况。通常,正式的审核过程分为5个步骤,即计划、预备会议(可选)、准备阶段、审核会议和问题追踪。

如果执行了所有的测试案例、测试程序或脚本,用户验收测试中发现的所有软件问题也都已解决,而且所有的软件配置均已更新和审核,可以反映出软件在用户验收测试中所发生的变化,用户验收测试就完成了。
