I am familiar with 3 main diagnostic tools linked to IT governance (COBIT, ITIL, OPM3). This article may be helpful, though I am not particularly sure how you might want to gauge public awareness/ attitudes of the tenets of these particular models. Perhaps recording behavioral responses/ surveys?

There so many research , surveys about the perception of people about IT governance using or benefiting from their frameworks for special purpuse of your reseach might be useful.

Dear Mr. Al Amin Rabby

Thanks for the information. I will try to understand the contents of the text carefully.

 Dear Mr. Arsalan Marsani Ahmed

Thanks for the information. I will learn more from 3 major diagnostic tools related to IT governance (COBIT, ITIL, OPM3). Perhaps there are important things that can be taken to help in my research later.

Dear Mr. Murat Onder.

Ok, thanks for the information and support.

Hopefully, I can finish my research well so it can be useful.
