  • CCAT is a private non-profit organization that administers various state & federal programs including: SBIR, Manufacturing & Supply Chain Initiative, Hydrogen Energy Coalition
  • eVSM’s tabular Excel output transforms a VSM from a strictly graphical representation of the manufacturing of a product line to a more easily used data format which is adequate for use in simulation, depending on the data stored in the VSM.
  • Completely automated build process through use of BCL scripting in addition to QUEST macro

I highly recommend any manufacturing company to tap into the CCAT’s state of the art offerings.” ~Continuous Improvement Manager for client
