What is important for a project manager to monitor throughout the project's lifecycle to ensure compliance?

A project manager must closely monitor external regulations throughout the project's lifecycle to ensure compliance. External regulations encompass legal requirements, industry standards, and organizational policies that govern how a project must be conducted. Adhering to these regulations is crucial because failure to comply can lead to severe consequences, including legal action, fines, and damage to the organization's reputation.

Monitoring external regulations enables a project manager to make informed decisions, modify project plans when necessary, and ensure that all project activities align with compliance requirements. This continuous oversight helps to mitigate risks and promotes accountability among team members regarding compliance standards.

The other options, while important in their own right, do not specifically address the compliance aspect across the entire project lifecycle. Vulnerability criteria is more relevant to risk management, rules of engagement pertain to team dynamics and communication, and stakeholder feedback involves gathering opinions and perceptions about the project rather than ensuring compliance with established regulations.
