The Materials Supply department in the municipality of Rotterdam manages the purchasing and delivery of outdoor space materials. They have an app called MATAF that allows contractors to easily order needed materials for projects such as remodeling. The application enables the department to prepare lists of required materials for projects months in advance and prepare them for call by contractors. As soon as an order is placed and approved via the app, it is processed by logistics planners and warehouse employees in the Oracle business management system. This includes creating orders with suppliers and scheduling deliveries to specific locations. Both external deliveries and material from the warehouse are managed and documented in this way for efficiency and traceability
