For large-scale projects, project structures must be defined and organizational charts designed. Schedules with contractual milestones must be created and coordinated. Project controlling must be ensured. Work packages must be defined, agreed upon, and approved (e.g., defining the scope of delivery, delineating deliveries, setting target costs and deadlines, defining and stipulating conditions). The project launch must be planned and executed, and project participants identified. Interfaces, deadlines, and deliverables must be coordinated with contractual partners. Interim results must be reviewed against milestones in the project timeline, and corrective actions, if necessary, clarified with customers, contractual partners, suppliers, and internal departments and adapted to the project status and progress. Economic targets and contractual obligations must be reviewed and ensured.
