Under cooperation framework with the Ministry of Interior, TI Cambodia collaborates with the Department of Functions and Resources to initiate discussion on development of the mobile application for citizens to report their feedbacks, suggestions and complaints on public services delivery at provincial and municipal One-Window Service and commune/sangkat service offices. In addition, the mobile app also provides access to information on some particular administrative services under commune/sangkat and one-window service mechanism. This tool is an innovative platform for provincial and municipal ombudsmen to collect citizens’ feedbacks, suggestions or complaints on public services and the mobile app will add more values to existing platforms, including complaint boxes and special desk that have received limited access from citizens.
