Exam GICSP Topic 1 Question 33 Discussion

The process described involves a defined quantity of ingredients being mixed and held for a fixed time before moving to the next step. This is a hallmark of a batch process.
Batch processes are executed in discrete lots or batches, where the process is started, controlled during the batch, and stopped or reset before the next batch.
Discrete processes (B) involve countable, separate units like assembled products.
Continuous processes (C) operate nonstop with steady conditions, common in chemical plants but not in batch brewing.
Distributed (D) refers to control architectures, not process type.
GICSP emphasizes the importance of understanding process types to tailor cybersecurity controls appropriate to their operational characteristics.
