Ensuring quality in a human resources-focused project such as this involves planning, evaluating, and continually improving based on measurable data and feedback. The project manager must: A: Collect feedback and conduct surveys/questionnaires # Direct feedback provides qualitative insights into team effectiveness and training outcomes. C: Document quality gaps and analyze them # This supports continuous improvement by identifying and addressing performance deficiencies. D: Develop a proper quality management plan # A measurable quality plan ensures consistent standards, metrics, and reviews throughout the project. Option B (hiring a certified expert) is not mandatory; the project manager can own quality responsibilities with proper planning and stakeholder engagement. Option E (using an external framework) can support performance but is not essential or sufficient alone for managing quality.
