The needs of the organization define the triggers within a business continuity plan (BCP). Triggers are the events or conditions that initiate the activation of the BCP. The triggers should be based on the organization's business objectives, risk appetite, recovery time objectives, and recovery point objectives. The triggers should also be aligned with the organization's information security policy, disaster recovery plan, and gap analysis.
However, these are not the primary factors that define the triggers, but rather the supporting elements that help implement the BCP. The needs of the organization are the main drivers for determining the triggers, as they reflect the organization's priorities, expectations, and requirements for business continuity. References =

The information security training policy ensures that everyone within the organization, including contractors and third-party users, receives the appropriate level of security awareness and training. This policy defines how the organization communicates its security requirements, expectations, and best practices.
"Information security training policies and programs ensure that all personnel are aware of and understand the security requirements and their individual responsibilities."
- CISM Review Manual 15th Edition, Chapter 3: Information Security Program Development and Management, Section: Security Awareness and Training The ISACA CISM practice questions emphasize that a clear training policy is the best way to communicate security practices to all involved parties.

The impact of noncompliance on the organization's risk profile is the MOST important information for the information security manager to communicate to senior management, because it helps them understand the potential consequences of not adhering to the established controls and the need for corrective actions.
Noncompliance may expose the organization to increased threats, vulnerabilities, and losses, as well as legal, regulatory, and contractual liabilities.

Metrics for an information security program should be aligned with the security objectives and strategy, and should demonstrate how well the program is performing in terms of reducing risk, enhancing security posture, and supporting business goals. Metrics that support major information security initiatives, reflect the corporate risk culture, or reduce information security program spending may be useful, but they are not the best approach for establishing metrics for the entire program.

The primary focus of a lessons learned exercise following a successful response to a cybersecurity incident is to evaluate how the incident management processes were executed, and to identify the strengths, weaknesses, best practices, and improvement opportunities for future incidents. A lessons learned exercise is not meant to determine the root cause, the attack vectors, or the recovery time of the incident, but rather to assess the performance and effectiveness of the incident response team and the incident response plan.
References: The CISM Review Manual 2023 states that "post-incident reviews are an essential part of the incident response process" and that "they provide an opportunity to assess the performance of the incident response team, identify areas for improvement, and document lessons learned and best practices" (p. 191).
The CISM Review Questions, Answers & Explanations Manual 2023 also provides the following rationale for this answer: "How incident management processes were executed is the correct answer because it is the primary focus of a lessons learned exercise, which aims to evaluate the incident response capability and to implement corrective actions and improvement plans" (p. 97). Additionally, the Cybersecurity Incident Response Exercise Guidance article from the ISACA Journal 2022 states that "The AAR [after-action review] should include the date and time of the exercise, a list of participants, scenario descriptions, findings (generic and specific), observations with recommendations, lessons learned and an evaluation of the exercise (strengths, weaknesses, lessons learned)" (p. 3)1
