A device can be in one of three states:
Full MDD
MDD as modified by MDR Article 120
Full MDR
In the first two cases, the MDD applies to the device. This includes the conformity assessment path, Annex I, etc.
Under MDR Article 120, the manufacturer cannot make any significant change in design or intended use. The guidance document provides the scope of significant change.
If the change is significant, then the MDR applies. If the change is not significant then MDD continues to apply. In the MDD case, revert to the NB's requirement for change notification. Generally, there are two in your contract - one for the device and one for the QMS.
In particular be cautious of MDD Annex II(4.4) which requires, "Changes to the approved design must receive further approval from the notified body which issued the EC design-examination certificate wherever the changes could affect conformity with the essential requirements of the Directive or with the conditions prescribed for use of the product".

Hello RAPS community,
As we finalize our internal SOP for managing changes post-DoA (for MDD-certified devices), I'm having some trouble interpreting the MDCG 2020-3 guidance.
This guidance categorizes changes as "significant according to Article 120" or "non-significant according to Article 120". It obviously does not give details of how "non-significant changes" will be handled by notified bodies, but our current interpretation for our own NB is that such changes will likely need to be submitted and approved/agreed upon as non-significant, similar to what we would now classify as a significant change. (And of course changes classified as "significant" are just not possible until full transition to MDR.)
The guidance doesn't do a great job (IMO) of talking about what we would currently call non-significant changes – i.e., those that don't need any submission at all, and can be implemented within our quality system as an internal documentation change. The only information I see about this is in the first few paragraphs of Section 4 of the guidance, but I find it very difficult to interpret.
What I'm mainly trying to understand is this: if you only follow the flowcharts, everything will come out as either "significant" (i.e., not possible) or "non-significant" (which we interpret to require a submission). There are no paths that point to "internal documentation". I assume in the absence of any specific guidance from our NB, we will need to create another flowchart that details our internal assumptions about what would fall into this internal documentation category. Is anyone aware of any additional guidance to help here? Or am I missing something very obvious in this guidance?
I'd be very grateful for any help from this community of experts!
