	EPRI's Digital Systems Engineering Framework is a collection of guides and methods designed to work as a single, integrated process to manage the lifecycle activities for modern digital technology integration in nuclear power environments. This process addresses the emerging complexity of nuclear plant integration to achieve safe and reliable plants and brings together the key technical topics that are relevant to the functional safety, security, and reliability of digital systems.

The updated DEG incorporates user feedback on the implementation of Rev. 0. It adopts a new structure organizing the activities by project phase (instead of by topic), which allows for better comprehension across the lifecycle and highlights all technical topics integration. The DEG Rev.1 centralizes all scoping/risk screens and route decision into Attachment A with instructions early in the DEG. This allows streamlined and efficient screening and scoping decisions.

In summary the DEG instructs the user about “How to Do”.

			It is important to note that while NISP-EN-04 requires the DEG, the DEG does not need and is unaware of NISP-EN-04. This allows the DEG to be used for systems and projects that scope out of the Standard Design Process (SDP) in the US or in other countries that have not implemented IP-ENG-001 and/or NISP-EN-04. In essence the DEG is a regulatory environment agnostic, practitioners guide, that helps with modern methods to efficiently plan and execute digital systems projects in nuclear environments.
