Testing is completed by IT support users without input from end users should be of most concern to a risk practitioner reviewing the system development life cycle (SDLC). This is because testing without input from end users can result in poor quality, usability, and functionality of the system, as well as increased errors, defects, and rework. Testing without input from end users can also lead to user dissatisfaction, resistance, and non-compliance, as well as misalignment with the business requirements and objectives. According to the CRISC Review Manual 2022, one of the key risk identification techniques for IT projects is to involve the end users and other relevant parties in the testing process1. According to the CRISC Review Questions, Answers
& Explanations Manual 2022, testing without input from end users is the correct answer to this question2.
Testing in phases, overriding segregation of duties controls, and using data anonymization are not the most concerning issues for a risk practitioner reviewing the SDLC. These are possible practices or techniques that can be used in the testing process, but they do not necessarily pose significant risks or problems. Testing in phases can help ensure that the system meets the technical and functional specifications, as well as the user acceptance criteria, at each stage of the development. Overriding segregation of duties controls can be justified and authorized during the testing phases, as long as the controls are restored and verified before the system goes live. Using data anonymization can help protect the privacy and security of the data used in the testing process, as well as comply with the relevant regulations and standards.

The best course of action when risk is found to be above the acceptable risk appetite is to execute the risk response plan, which is the set of actions and measures that are designed to reduce, avoid, transfer, or accept the risk. The risk response plan is based on the risk assessment results, the risk appetite and tolerance of the organization, and the cost-benefit analysis of the risk response options. The risk response plan helps to achieve the optimal balance between the potential benefits and threats of the risk, and to align the risk decisions with the organizational objectives and context. The other options are not the best courses of action, as they are either too passive or too reactive in dealing with the risk. Reviewing risk tolerance levels may help to adjust the acceptable variation between the risk thresholds and the business objectives, but it does not address the actual risk level or impact. Maintaining the current controls may help to prevent the risk from increasing further, but it does not reduce the existing risk exposure or mitigation. Analyzing the effectiveness of controls may help to identify the gaps or weaknesses in the current risk management, but it does not implement the necessary improvements or changes.

A strong risk-aware culture is reflected by transparent communication about risks. Open discussions signify employee engagement and ownership of risk-related issues.

* A risk assessment of a production system is a process of identifying, analyzing, evaluating, and treating the risks that may affect the performance, quality, or safety of the production system, which is a system that transforms inputs into outputs using various resources, processes, and technologies12.
* The most appropriate action for the risk manager to take after undertaking a risk assessment of a production system is to inform the process owner of the concerns and propose measures to reduce them, which is a process of communicating and consulting with the person who is responsible for the design, operation, and improvement of the production system, and suggesting possible risk responses that can prevent, mitigate, transfer, or accept the risks34.
* This action is the most appropriate because it ensures the involvement and collaboration of the process owner, who has the authority and accountability to implement and monitor the risk responses, and who can provide feedback and input on the feasibility and effectiveness of the proposed measures34.
* This action is also the most appropriate because it supports the risk management process and objectives, which are to identify and address the risks that may affect the achievement of the organization's goals and the delivery of value to the stakeholders34.
* The other options are not the most appropriate actions, but rather possible alternatives or supplements that may have some limitations or drawbacks. For example:
* Recommending a program that minimizes the concerns of the production system is an action that involves designing and planning a set of coordinated and interrelated activities and tasks that aim to reduce the likelihood or impact of the risks34. However, this action is not the most appropriate because it does not involve the process owner, who is the key stakeholder and decision maker for the production system, and who may have different views or preferences on the risk responses34.
* Informing the development team of the concerns, and together formulating risk reduction measures is an action that involves communicating and consulting with the group of people who are responsible for creating, testing, and deploying the products or services that are produced by the production system, and jointly developing possible risk responses34. However, this action is not the most appropriate because it does not involve the process owner, who is the primary owner and user of the production system, and who may have different needs or expectations on the risk responses34.
* Informing the IT manager of the concerns and proposing measures to reduce them is an action that involves communicating and consulting with the person who is responsible for managing and overseeing the IT resources, processes, and systems that support the production system, and suggesting possible risk responses34. However, this action is not the most appropriate because it does not involve the process owner, who is the main stakeholder and beneficiary of the production system, and who may have different requirements or constraints on the risk responses34.

After a risk has been identified, the risk owner is in the best position to select the appropriate risk treatment option. The risk owner is the person or entity with the accountability and authority to manage a risk1. The risk owner is responsible for evaluating the risk, choosing the most suitable risk treatment option, implementing the risk treatment plan, and monitoring and reviewing the risk and its treatment2. The risk owner has the most knowledge and stake in the risk and its impact on the objectives and activities of the organization. The other options are not the best choices for selecting the risk treatment option, as they do not have the same level of accountability and authority as the risk owner. The risk practitioner is the person or entity with the knowledge and skills to perform the risk management activities1. The risk practitioner can assist the risk owner in identifying, analyzing, evaluating, and treating the risk, but the final decision and responsibility lies with the risk owner. The business process owner is the person or entity with the accountability and authority to manage a business process3. The business process owner may be affected by the risk or involved in the risk treatment, but the risk owner is the one who has the overall responsibility for the risk. The control owner is the person or entity with the accountability and authority to ensure that the controls are properly designed, implemented, and operated4. The control owner can provide input and feedback on the effectiveness and efficiency of the controls, but the risk owner is the one who decides which controls are needed and how they are applied.
