The Conference Proposals Interface (CPI) is a web-based tool that assists in the preparation of proposals by creating a clean baseline document (a "skeleton") upon which proposed modifications can be indicated. Those who have submitted proposals to other major ITU events such as the ITU Plenipotentiary Conference 2014
(PP-14), the World Radiocommunication Conference 2015 (WRC-15), or the World Telecommunication Standardization Assembly 2016 (WTSA-16) will be familiar with CPI.
