How to use Requirements management tool? Is there any study material or video for this?
your question is quite broad, are you asking for Knowledge about PTC Integrity?
If yes, you should book a traning class which teaches you in how to use Integrity.
If you are rather looking for a generic requirements management training, then any 3rd party training university offers such classes, incl. certifications as vertified requirements manager in differenet levels.
Does this help?
