Hi,

I found a very interesting intro online.

Apart from what was discussed, some of other common problems that arise include the following:

-Product developers do not have a finalized design.
-Business managers and technical experts do not grasp the scope of the design transfer effort and underestimate the amount of time and effort required.
-Manufacturing processes have not been developed, documented, or validated.
-Developers have not created a vendor supply chain based on an approved-vendor list.
-Developers bring unresolved cost, reliability, or safety issues to the manufacturer.
-The design transfer process is well understood by both parties, but the inability to plan the transition of a product design into a controlled manufacturing environment results in slow starts and unacceptable delays.
-The purchasing department does not have enough time to identify and approve new vendors, verify component specifications, and update the manufacturing planning system.
-The workflow of the manufacturing organization is disrupted by having to wait for released materials, procedures, and test fixtures.
-Delays occur even after all the documentation is approved, because manufacturing must receive, inspect, and finally release parts for production.
Failure to appreciate these challenges inevitably leads to unnecessary project delays, frustration, and misunderstandings between the developer and manufacturer. It is a reason some firms have not taken full advantage of the benefits that an outsourcing relationship can provide.
