A DPP readiness review may touch supplier declarations, bills of materials, technical files and commercially sensitive data. The engagement should therefore start with the minimum information needed and clear handling expectations.
Do not start by emailing an entire engineering repository. A product list, one representative technical datasheet and a high-level document inventory are normally enough to determine whether the scope makes sense.
If the project proceeds, the transfer method and confidentiality requirements can be agreed before more sensitive material is shared. Email may be appropriate for ordinary business documents; more sensitive or larger technical datasets may justify a different agreed transfer route.
Source files often contain third-party information, supplier-use restrictions or internal notes that do not belong in the final DPP dataset. DPPPrep separates the working evidence layer from the structured output rather than assuming that every source document should be published or exposed.
We do not publish generic claims such as a particular ISO certification, guaranteed encryption architecture or fixed deletion period unless that control is actually part of the engagement. Where a client requires defined security controls, retention periods, approved processors or transfer mechanisms, those requirements should be agreed explicitly before sensitive data is exchanged.
