Najme: It sounds like you are looking to understand the structure of ISO committees. You can get all these definitions at iso.org, which is a better option than having me explain them incorrectly. Suffice to say that a Technical Committee (eg. 215 Health Informatics) uses working groups (WG's), Task Forces (TF's), Ad hoc Groups (AHG's) to get it's business done. You can learn more at iso.org.
Hello. I hope you are fine. Having studied the ISO/TC 215 - Health informatics, I decided to ask you one question. According to the mentioned link "www.iso.org/committee/54960.html", I understood you have different parts in ISO/TC215 including AHG,CAG,TF,WG and JWG but I couldn't understand what you mean from it. Could you please explain about it
