对审计业务执行独立复核是指大多数会计师事务所的质量政策都要求，事务所的任何审计业务均应得到负责该项目的合伙人的独立复核。

【正确答案】：（1）没有按照有关规定定期轮换签字注册会计师。会计师事务所签字注册会计师与鉴证客户长期交往，会产生密切关系影响独立性，W注册会计师已经连续5年担任M公司的签字注册会计师，应当予以轮换。（1分）
（2）签字注册会计师不符合要求。按照有关文件，审计报告应当由会计师事务所主任会计师或其授权的副主任会计师和一名负责该项目的注册会计师签字。担任签字注册会计师的W和Y注册会计师都不是会计师事务所的主任会计师或其授权的副主任会计师。（1分）
（3）业务执行方面存在问题。风险评估程序（了解被审计单位及其环境）是必须的，不得省略而直接实施进一步审计程序。（1分）
（4）审计资源不足。甲会计师事务所2010年才具有承接上市公司审计的资格，由于审计资源的限制，以及人员专业能力的不足，所以对于直接承接M公司的业务存在专业胜任能力上的缺陷，不应接受该业务的委托。（1分）
（5）项目质量控制复核人员不当。应该安排不参与项目的人员作为项目质量控制复核人员，项目组的人员不能作为项目质量控制复核人员。（1分）
（6）如果存在意见分歧必须解决，否则不能签署审计报告，不能直接采纳项目质量控制复核人的意见。（1分）
Answer：
1. The CPA firm doesn’t rotate the CPA signing for the report periodically. The CPA signing for the report has a long and close relationship with the client, which will influence the CPA’s independence. The CPA W has been the senior auditor signing for the report for 5 years in a row, so he should be rotated.
2. The CPA signing for the report is not in compliance with the standards. According to the standards, the audit reports should be signed by the chief auditor or the vice-chief auditor authorized by the chief auditor and the CPA in charge of the auditing project.
3. The auditing implementation is incorrect. According to the auditing standards, the risk assessment procedures are necessary. The CPA firm is not allowed to omit the risk assessment procedures and to do the other procedures directly.
4. The audit recourses are not adequate. The CPA firm just got the qualification of auditing the listed companies in 2010.Due to limited resources and inadequate competence of the staffs, the CPA firm should not accept the engagement.
5. The person responsible for review is inappropriate. The firm should arrange the person who is out of the audit team to be responsible for review. The team member cannot be responsible for review
6. The differences in opinion must be resolved before signing for the report, The opinions of the person responsible for review cannot be accepted directly
