PLM? What does the abreviation stand for and why on earth would you want to complicate your cad system any more than it is alread?
It appears to me that everyone wants to pack all the work and blame on the engineering groups. The real blame is the upper management being greedy and having little or no knowledge of how to run a business to start with. so it is a try this or try that to see if it will work.
Everyone needs to get bet back to the basic of using simple processes and good common sense with a little solid knowledge on how to run a company. Whether the company is large or small the rule still applies!
