RPA, IPA, BPA: three acronyms that get used interchangeably and shouldn't be. They solve different problems, and picking the wrong one means either over-engineering a simple task or under-powering a complex one. Here is the decision guide.
Business Process Automation (BPA)
The orchestration layer: codeless or low-code workflows for approvals, handoffs, and routing across people and systems. Best when the bottleneck is a process, like a request waiting on three sign-offs, rather than data entry.
Robotic Process Automation (RPA)
Software robots that mimic clicks and keystrokes to move data between systems that don't integrate cleanly. Best for high-volume, rules-based, repetitive tasks like order entry, invoice matching, and report pulling, especially against legacy apps without APIs.
Intelligent Process Automation (IPA)
RPA plus AI. It handles the cases that aren't perfectly structured: reading a document, classifying an email, making a judgment call inside an otherwise automated flow.
Rule of thumb: BPA moves the work between people, RPA moves the data between systems, IPA handles the parts that need a little judgment.
How to choose
- Is the bottleneck approvals and handoffs? Start with BPA.
- Is it high-volume copy-paste between systems? Start with RPA.
- Does it require reading or deciding mid-process? You want IPA.
