sub-process
This glossary entry explains sub-process for AI governance and model risk programs. The sections below summarize what the term means in plain language, why chief AI officers and cross-functional committees track it, where teams often get confused, and—when you are signed in—how it shows up across major industries and in expectations tied to the EU AI Act and NIST AI RMF.

What It Means
A sub-process is a smaller, specific workflow that sits inside a larger business process. Think of it like a recipe step that can be used in multiple different recipes - it's a reusable chunk of work that accomplishes one particular task within bigger operations.
Why Chief AI Officers Care
Sub-processes are critical for AI automation because they represent the building blocks that AI systems can learn, optimize, and execute independently. When you break down complex operations into well-defined sub-processes, you can apply AI more effectively to each piece and create more reliable, scalable automated workflows.
Real-World Example
In customer onboarding, you might have sub-processes for 'identity verification,' 'credit checking,' and 'account setup.' The identity verification sub-process could be reused across loan applications, new credit cards, and investment accounts - each following the same steps but within different parent processes.
Common Confusion
People often confuse sub-processes with simple task lists or think they're just smaller versions of full processes. The key difference is that sub-processes are standardized, reusable components that maintain their own complete workflow while serving multiple larger processes.
