I'm starting to put together a proposal to implement Enterprise PDM in our company and I'm looking for your help to buid my case.  What I'd like is points on the following:

• how has EPDM helped your company become more successful/profitable since implenting it?
  
• how has EPDM helped you do your job better?
  
• how has EPDM helped you enjoy your job more?
  
• key features of EPDM that help with the first 3 points
  

Thanks in advance for your help.
