I have earlier read a thread by Vivek and Janev on a forum question on Revision levels. However, I am still confused by it. Do we need to use Revision Level together with Engineering Change Management (ECM) ? I understand that one allows to you to keep track of how many revisions you have made (Revision Level), while ECM allows you to know why you made the change and when it is valid. Is there further details on why they are used?
Thanks so much.
