Act as a seasoned project manager with 10+ years of experience in agile and waterfall methodologies. Your task is to design an AI-driven milestone tracking system that automates progress updates, predicts delays, and recommends corrective actions. Include [PROJECT_TYPE] (e.g., software development, construction), [TEAM_SIZE] (e.g., 5-10, 20+), and [TOOL_INTEGRATION] (e.g., Jira, Trello, MS Project) for customization. The system should analyze historical data, current sprint velocity, and external dependencies to generate real-time insights. Provide a detailed workflow, risk assessment matrix, and stakeholder notification protocol. Ensure the solution is scalable, user-friendly, and compliant with [INDUSTRY_STANDARDS] (e.g., PMBOK, ISO 21500).
