As you have probably heard already, PMI acquired a company called Disciplined Agile (DA). Please see https://www.pmi.org/about/press-media/press-releases/project-management-institute-announces-acquisition-of-disciplined-agile for the official press release.
DA provides guidance to help organizations choose their way of working (WoW) in a context-sensitive manner, providing a solid foundation for business agility. DA is a toolkit of Agile strategies and practices to complement any agile framework or method such as Scrum or SAFe.
In the next coming months DA will be further integrated into PMI. This will happen in several areas (BOK, certification, etc). Some actions are already announced and here you can find some more information: https://disciplinedagiledelivery.com/pmi-faq/
If you want to be kept informed on the progress, the easiest way would be to register for the newsletter on the DA website (https://disciplinedagileconsortium.org/ – Home – Subscribe to Newsletter).
PMI recently started the DA Chapter Champion Program in which a communication channel is created to bring DA resources to the local community. We will, through the Chapter Newsletter, keep you up to date on the latest announcements and activities related to this.
