 The decision to accept an IT control risk related to data quality should be the responsibility of the business owner. The business owner is the person who has the authority and accountability for the business process that relies on the data quality. The business owner should understand the impact of data quality issues on the business objectives, performance, and compliance. The business owner should also be involved in defining the data quality requirements, assessing the data quality risks, and implementing the data quality controls or mitigation strategies.

Parallel processing is a system implementation approach that involves running the new system and the old system simultaneously for a period of time until the new system is verified and accepted. The primary advantage of parallel processing is that it provides assurance that the new system meets performance requirements and produces the same or better results as the old system. Parallel processing also minimizes the risk of system failure and data loss, as the old system can be used as a backup or fallback option in case of any problems with the new system.

Data loss can occur due to various reasons, such as accidental deletion, hardware failure, malware infection, theft, or unauthorized access. Data classification procedures can help to identify and protect sensitive data, but they are not sufficient to prevent data loss. The most effective way to protect against data loss is to conduct periodic security awareness training for employees, which can educate them on the importance of data security, the best practices for data handling and storage, and the common threats and risks to data. 

 A post-implementation review is a process of evaluating the outcome and benefits of a project or a system after it has been implemented. The main purpose of a post-implementation review is to determine to what extent the business requirements are being met by the new system. Therefore, the most likely aspect to be assessed is the results of line processing, which refers to the actual performance and functionality of the system in the operational environment.
