Critical Design Reviews (CDR) are an essential formal check-point in the product development process. They ensure designs are fit for purpose, ready for production and checked before further financial investment.

An organised and robust CDR helps to identify mistakes, highlights risks, any concerns or areas for optimisation and any further improvements to the design. A thorough CDR saves time, reduces risks and shares responsibility across all stakeholders.

Designer’s Self-Checks (in preparation for a CDR meeting)

Once you have covered the above points, the next stage is to request a formal in-house CDR. Invite along the design team, design manager, and all key stakeholders, who may include manufacturing representatives, clients etc. Use BS.7000:2 to help you identify who should be in the meeting for your business.

Critical Design Review Meeting

The goal of any CDR meeting is to make sure designs meet the requirements of all interested parties. Remind those attending the CDR of their responsibility in it too. It’s a shared responsibility, not just the designers to make the project a success!

The project’s lead designer should be prepared to cover the following agenda:

Following the meeting, minutes should be complied and distributed to those involved.

Once approved, the design team can work on the agreed changes.

Once the changes are deemed complete, then organise a ‘back mod’ review meeting with your design management team to ensure changes are complete. If so, then the Design Manager will formally approve the designs for prototype manufacture.

By keeping to a formal method of review, you can limit your exposure to unnecessary risk which could hinder your project, in terms of its delivery schedule, development costs and ultimately the return on investment. Hopefully, these guidelines are useful and help you develop your own formal review system.
