A new team member joins the project and fails to apply the project-specific quality assurance...

Project-specific QA expectations must be communicated and made accessible to everyone who performs the work. Ensuring the new team member had access to the quality management plan (D) is the most direct preventive action because this plan defines the project’s quality standards, processes, roles, tools, checklists, audits, and acceptance practices. Access supports consistent execution and helps onboarding: the person can learn “how we do quality on this project,” not just generic QA concepts. External QA training (A) may improve general capability but does not guarantee alignment with the project’s specific procedures and compliance needs. Delegating QA tasks (B) shifts responsibility rather than building team-wide quality ownership; it also creates a single point of failure. Ensuring understanding of “all requirements” (C) is important, but it addresses what to build, not how to assure quality while building it. Making the quality plan available (and onboarding the member to it) supports prevention over inspection, reduces defects and rework, and aligns with PMP process discipline around planning quality management and managing quality throughout execution.
