Biomed Design Validation is used at the stage where a design that has been developed from the, VMP / URS /GAMP 5 / cGMP / and other Health and Safety Guidelines, is reviewed and documented by competent persons to ensure that the designed equipment, if built, will satisfy all the detailed specified requirements.
Validation Online has documented many times before the importance of paying attention to ensuring testing and inspection stages are traceable back to user requirements. Well here we are again; you have taken great trouble to write, and get approved a URS and a
VP, now a vendor (or could be in house) has come forward and presented a design that they have prepared, and they state it will satisfy your requirements. The FDA maintain; that this is the stage where the great majority of project problems are manufactured, not obvious immediately, but materializing later in the project time line.
The Design Qualification is the only document that is going to confirm that the design will work. It must be carried out by qualified people who can challenge the design performance. If you have no such persons on your staff you must contract them in, or contract the DQ out.
When I arrive on site to manage a project, my very first task is always to get to grip with the design, get all the drawings and review them. I do this because thirty years of experience has made me very aware, that I need to know the design is good. So often this is not the case, and very often there are glaring abnormalities. When these are highlighted with the client and their vendors, only the vendors are smiling. The client had accepted the design and the vendor had quoted for that design, any changes will be extra to the quoted price. Sometimes this has run into seven figures.
A DV can also be used where a company has prepared a User Requirements Specification (URS) for a piece of equipment and is searching for a manufacturer, but is offered equipment Of-The-Shelf. A DV can be used to verify whether the off-the-shelf item will fully deliver the functionality specified in the URS, whilst complying with all relevant cGMP requirements and all applicable health and safety issues.
The scope of the DV must include but is not limited to:
