A mix...pen and paper for a lot of operations and QA records. In addition we have separate systems we use for various things such as QA monitoring (SPC software), warehouse and inventory and purchasing ERP system, sharepoint for documents and SOPs, network folders for miscellaneous documents / records.
We have a goal that by second quarter of 2020 we are completely paperless. But...I can tell you we won't meet that goal. We have too many initiatives and other things going on. Plus as we add more electronic systems to manage our stuff we are finding they do not play well together. The latest being a WMS system as an add on to our ERP system.
The real problem is no one really takes point or dictates on what system to use what and how to best use it. Our sharepoint is a complete mess...blah.
The best ERP system I've used is DEACOM. It was a great system because it allowed some flexibility and nuance, but had stable systems in place behind it. It really helped to streamline a lot of our processes from product development to commercialization, to our allergen management program, and traceability. I could do a full item (raw material or finished good) in a few clicks of a button. I think the main reason this system was successful is because upper management went all in on it; they didn't get the "partial package" which a lot of companies do with ERP systems. Then they find later on they needed a separate package for WMS, or product traceability, or production yields.
