1.4 Single Window Implementation Process
Single Window initiatives are complex and lengthy projects. A project involves many different
political and technical actors and requires activities of a different nature, including IT design
and coding, business process analysis, legal assessment and drafting, and data harmonisation
and simplification.
1.4.1 Gradual Implementation
Single Windows are often rolled out in phases, gradually increasing the capacity and
functionalities of the Single Window over time – see Box 3 for the example of the Indonesian

Box 3: Gradual deployment of the Indonesian Single Window
The Indonesia National SW (INSW) has followed a gradual development process. The first
trial end 2007, was limited to three Government Agencies in the port of Tanjung Priok; the
second stage in July 2008 covered five sea ports; the third stage expanded the INSW to all
import procedures in the ports; the fourth stage in July 2009 covered import procedures for
Government Agencies (GA) in seaport, airport and dry-port; in January 2010; the fifth stage
made the use of the INSW mandatory of all import procedures in five ports; and in the final
phase the INSW was extended to 21 ports and all import-export procedures.
