If you work in pharmaceutical or biotech manufacturing, you’ve probably had to think about 21 CFR Part 11, the FDA regulation that governs electronic records and electronic signatures. Most of the Part 11 requirements live in supervisory systems like SCADA, MES, and historians. But those systems depend on one thing: reliable, traceable data from the equipment layer. That’s where Opto 22’s *groov* platforms come in.
