The DMR at our company is a formally controlled quality system document. Technical files are more Regulatory at our company, and are not accessible to everyone. DMRs are. We are a contract manufacturer. There is one for each product, and we use it as a document index. There are no references to the document revision levels as those are on the documents themselves, as well as the document history, including ECO number. If you need a template I have one.
The principle behind using the DMR as an index all documents, drawings, etc. that are used to build a device is that it makes auditing easier, and is a great resource for new people who are not familiar with the device.
It is structured like this:
DEVICE MASTER RECORD
Product Description: (Noun name, modifier, value)
Design history file: (This could be your project file with design xfer.)
Raw materials spec: (doc number, no revision. Go to document
itself for the current revision number and
Bill of Material: (doc number) BOM has component numbers of
Drawing number: (Drawing number(s))
Manufacturing procedures: List doc numbers
Quality assurance procedures: List doc numbers
Fixtures: See individual manufacturing and quality assurance specs. (We do not list fixtures on DMR and in specs. Only at point of use.)
Software: Name software packages
Packaging info: Shelf life in days
Number of units in this configuration that is shipped
(eaches, 10 to a carton, what. A DMR for each
Labeling: Labeling procedure
Label printing spec: Doc number
Post Packaging testing: Doc number
Sterilization: Doc number
Post sterilization inspection and testing: Doc number
Inspection and release procedures: Doc number
Shipping: Doc number
At the end of the document is the revision history including rev. number, effective date, ECO number, and short description of change.
