The Work Plan provides details of co-operation between all the 3GPP TSGs and WGs on reaching common targets.
These targets are called "Features", and are new or substantially enhanced functionality which represents added value to the existing system.
A feature should normally embody an improved service to the customer and / or increased revenue generation potential to the supplier. The features are divided into "Building Blocks" and "Work Tasks", which lead to the production of Technical Specifications (or Reports) and / or Change Requests to existing Specifications.
3GPP Technical Report 21.900 - "Technical Specification Group working methods" is a very good starting point if you wish to learn more about how the Work Plan is managed.
All current Work Item Descriptions (WIDs) are kept in a directory on the 3GPP FTP Server.
