ISA-88 Part 1 gives the foundation for making Batch. The majority of functionality in use of ISA-88 has been guided and directed by the Control Systems Suppliers way of interpretation and implementation of the standard.

This paper focuses on the Batch functionality provided in the Batch software packages and compares this to what is actually included in (or what was actually the intention of) ISA-88. The paper will highlight the mayor similarities and outstanding functions but also the shortcomings and lack of functionality both in the Batch software packages and the ISA-88 standard itself.

Based on the author 15+ years of experience in making real Batch applications in the Biotech & Pharmaceutical industries, the need for enhancements and clarifications of both the ISA-88 standard as well as the Batch software packages functionality in order to enable Batch practitioners to meet the Process requirements and to enable building Batch applications even simpler and easier will be described by use of Process examples.
