• Collaborate with project managers, engineers, finance, and other stakeholders to ensure schedule integration and alignment with business goals.
• Support change and risk management processes by evaluating schedule impacts and conducting scenario planning.
• Monitor and report on schedule performance metrics, including earned value, schedule variance, and forecast accuracy.
• Drive continuous improvement in scheduling practices, tools, and reporting by applying best practices and business insights.
• Contribute to the development and implementation of digital dashboards and reporting tools for schedule tracking and performance visualization.
