CiA technical groups
CiA technical groups are hierarchical structured. The top-level CiA technical group is the CiA Technical Committee (TC); sub-layered are the CiA Interest Groups (IG). There are three active IGs: CANopen, CAN FD and commercial vehicles. The IGs manage their related Special Interest Groups (SIG) and Joint Task Forces (JTF). JFTs are established jointly with other nonprofit associations. All these CiA technical groups develop CiA specifications and recommendations. Each CiA member may participate in any group. The groups decide on consensus, meaning they discuss until everybody agrees on the compromise.

Based on consensus
Each CiA member may participate in any group. The groups decide on consensus, meaning they discuss until everybody agrees on the compromise.
A genuine leader is not a searcher for consensus but a molder of consensus.
Glossary of terms
CiA provides the glossary of terms to support a common understanding of terms and definitions in the CAN application field.
CiA working groups can refer to these terms. Proposals for missing terms are highly appreciated and can be submitted to secretary(at)can-cia.org.
