Arguably one of the most important standards for batch and process manufacturing is ISA88, commonly called the "batch standard." For years, although the responsibility for updating the standard belongs to the ISA88 committee, the WBF (formerly World Batch Forum) has been the educator, torchbearer and prostelyzer for both the "batch standard" and ISA95, the manufacturing standard. There's a revolving door between ISA88, ISA95 and WBF, and there likely always will be.
