I have a full-time job at a Fortune 250 company which has given me intimate experience with several enterprise MRP systems.
But the business I'm starting is my side gig (sole proprietor at this point). I have a couple suppliers and outside service vendors, and will be doing some precision CNC woodwork. Would love to tell more about it but I'm holding off until some thing are worked out. I expect to add a shiny new link to the website in my signature before too long
I do like the product configuration idea, ala 'Enovia'. I'm using opendocman (
http://www.opendocman.com/) for this now, but a product configuration suite would do a little more, I think. Part numbers and routings should be revision controlled.
