The best course of action for a newly hired risk practitioner who finds that the risk register has not been updated in the past year is to identify changes in risk factors and initiate risk reviews. This would help the risk practitioner to update the risk register with the current and relevant information on the risks facing the enterprise, such as their sources, drivers, indicators, likelihood, impact, and responses. It would also help the risk practitioner to evaluate the effectiveness of the existing controls, and to identify any new or emerging risks that need to be addressed. Identifying changes in risk factors and initiating risk reviews would enable the risk practitioner to maintain the accuracy and completeness of the risk register, and to provide valuable input for the risk management process.

Identifying risk events is essential for developing realistic and relevant risk scenarios. This step enables the creation of scenarios that reflect actual vulnerabilities and potential disruptions, adhering to the CRISC's focus onRisk Identification.

The greatest concern for a risk practitioner when an organization is adopting blockchain for a new financial system is the limited organizational knowledge of the underlying technology. Blockchain is a distributed ledger technology that enables secure and transparent transactions among multiple parties without the need for intermediaries or central authorities. Blockchain technology has many potential benefits for the financial sector, such as reducing costs, increasing efficiency, enhancing security, and improving trust. However, blockchain technology also poses many challenges and risks for the organization, such as technical complexity, interoperability issues, regulatory uncertainty, and cultural resistance. The limited organizational knowledge of the underlying technology is the greatest concern, because it affects the ability and readiness of the organization to adopt, implement, use, and maintain the blockchain system effectively and securely. The limited organizational knowledge could also result in poor decision-making, inadequate governance, insufficient training, and increased vulnerability to errors, fraud, or attacks. The other options are not as concerning as the limited organizational knowledge, although they may also pose some difficulties or limitations for the blockchain adoption. Lack of commercial software support, varying costs related to implementation and maintenance, and slow adoption of the technology across the financial industry are all factors that could affect the feasibility and sustainability of the blockchain system, but they do not directly affect the capability and maturity of the organization.

According to the CRISC Review Manual (Digital Version), assessing changes in residual risk is the best approach for determining whether a risk action plan is effective, as it measures the impact and value of the risk response actions and controls on the risk level. Residual risk is the risk that remains after the risk response actions and controls have been implemented. Assessing changes in residual risk helps to:
Evaluate the extent to which the risk response actions and controls have reduced the likelihood and/or impact of the risk to an acceptable level Identify and report any deviations, errors, or weaknesses in the risk response actions and controls and their performance Recommend and implement corrective actions or improvement measures to address any issues or deficiencies in the risk response actions and controls Monitor and measure the effectiveness and efficiency of the risk response actions and controls and their alignment with the organization's risk appetite and risk tolerance Update the risk register and the risk treatment plan to reflect the current risk status and the residual risk levels References = CRISC Review Manual (Digital Version), Chapter 3: IT Risk Response, Section 3.2: Risk Response Process, pp. 161-1621

Unavailability of critical IT systems poses the greatest risk to an organization's operations during a major IT transformation, because it can disrupt the business continuity, productivity, and performance of the organization. Unavailability of critical IT systems can also cause financial, reputational, or legal damages to the organization, and affect the quality and delivery of products or services to the customers. The other options are not the greatest risks, although they may also pose some challenges or threats to the organization during a major IT transformation. Lack of robust awareness programs, infrequent risk assessments of key controls, and rapid changes in IT procedures are examples of management or process risks that can affect the planning, execution, or monitoring of the IT transformation, but they do not have the same impact or severity as the unavailability of critical IT systems.
