Summary#

This SOP describes how we evaluate and make changes to our software after it’s released.

General Considerations#

Feedback Classification#

Feedback is either classified as a bug fix or a regular change request:

  • Bug fixes: By definition, bug fixes only constitute minor changes to the software code and complement existing device features instead of introducing new ones or removing existing ones. Bug fixes must not 1) Constitute significant changes to the medical device as defined by the criteria outlined in the change assessment list and 2) Introduce new risks or failure modes

  • Regular Change Requests: All other changes that are not classified as a bug fix.

Guidance Documents#

The processing of changes is based on the following regulatory provisions and guidances:

  • Medical Device Directive, Annex II Section 3.4 and Section 4.4

  • Medical Device Regulation, Annex IX Chapter II Section 4.10: “Changes to the approved device shall require approval from the notified body which issued the EU technical documentation assessment certificate where such changes could affect the safety and performance of the device or the conditions prescribed for use of the device. Where the manufacturer plans to introduce any of the above-mentioned changes it shall inform the notified body which issued the EU technical documentation assessment certificate thereof. The notified body shall assess the planned changes and decide whether the planned changes require a new conformity assessment in accordance with Article 52 or whether they could be addressed by means of a supplement to the EU technical documentation assessment certificate. In the latter case, the notified body shall assess the changes, notify the manufacturer of its decision and, where the changes are approved, provide it with a supplement to the EU technical documentation assessment certificate.”

  • Medical Device Coordination Group (MDCG) Document 2020-03: “Guidance on significant changes regarding the transitional provision under Article 120 of the MDR with regard to devices covered by certificates according to MDD or AIMDD”

  • EK-Med 3.9 B31 dated 11/2014 and NBOG BPG 2014-3 dated 03/2014

Process Steps#

1. Creation of Change Request#

Changes proposals can originate from various sources, e.g.:

  • Internal design ideas

  • Market research

  • Customer feedback (see process for feedback management)

  • Post-Market Surveillance (see process for post-market surveillance)

They can originate from anywhere inside the company.

The Product Manager creates a change request ticket in the company’s project management software with a description of the proposed change.

2. Evaluation of Change#

The Product Manager, together with a Regulatory Affairs Manager and the Head of Software Development, then evaluates the proposed change. In a first step, it is assessed if the change constitutes a bug fix or not. In case of a bug fix, the Product Manager directly proceeds with the evaluation as part of the bug fixes documentation list (link here).

If the change does not constitute a bug fix but rather a regular change request, it is evaluated whether the change:

  1. Is a significant change (refer to e.g. MDCG 2020-03 for guidance)

  2. Introduces any new risks and whether those are acceptable

  3. Impacts any existing risk control measures

  4. Is technically feasible

  5. Makes sense for the product strategy of the company

The evaluation is documented as part of the Change Evaluation List and results in a decision on whether the change is implemented and whether the Notified Body needs to be involved if the change is significant. These two decisions are documented in the change request ticket.

If required, a Notified Body shall be informed before the implementation of changes. Multiple proposed changes can be batched and discussed in one session.

3. Implementation, Verification, Validation, Update of Documentation#

Change requests result as input to the SOP Software Development and are implemented accordingly.

This includes verification, validation and release activities while ensuring traceability. The relevant documentation is updated and released with an updated declaration of conformity.
