A Single Window common data repository provides a more complete view of business
operations and deeper insight into critical business processes. It also enables additional
services, such as business intelligence and data mining, and therewith allows for integrated
risk management (IRM). It also makes integration of future change requests at the level of
application and services simpler as these changes are implemented in one location on the level
of the common data model.
2.1.8 Single Window Interoperability
Interconnectivity and interoperability, meaning the ability to exchange of data and information
across systems, are now becoming important aspects of Single Windows. Recent Single
Window visions such as the WCO Single Window perspective clearly stress the fact that Single
Windows operate in an environment that is made up of multiple functional IT systems and
only jointly have the ability to deliver trade facilitation services 25. To better respond to
complex regulatory challenges and to improve the delivery of services to traders, a Single
Window has to embed system-to-system connectivity or services. This enables Single
Windows to provide to agencies collaborative, networked and interconnected workflows and
business processes.
