RPA vs AI vs Scripting: Which Should You Choose?
Most real workloads need a mix of technologies — and AI is usually the smallest part of it. Here's how to match each piece of work to the simplest tool that can do it.

WE DON'T START WITH AI. WE START WITH THE WORK.
Not every problem needs AI. We choose the technology based on the work — and introduce AI where it genuinely adds value.
Five technologies, each with a job.
Each is the right answer for a particular kind of work — and the wrong one when used out of place.
Workflow
Predictable, rules-based steps that move work between people and systems — routing, approvals, hand-offs, reminders.
Routing an invoice to the right approver by amount and cost centre.
Automating a messy process as-is just makes the mess faster. Simplify first.
Integration
Moving data directly between systems through their APIs, so nobody re-keys it.
Posting approved journal entries from one system into the ERP.
Needs a system that exposes an API — check before you design around it.
Scripting
Predictable, repeatable technical tasks — clean-ups, checks, scheduled jobs and known fixes.
Clearing disk space and restarting a service when a known alert fires.
Scripts nobody owns become risk. Give every one an owner and monitoring.
RPA
Working through a screen when an application has no practical API — typically legacy software.
Copying order data out of an old desktop application into a modern system.
Breaks when the screen changes. Prefer integration wherever an API exists.
AI
Work that needs interpretation — unstructured documents, natural language, classification or judgment.
Reading supplier invoices in different layouts and extracting the fields.
Costlier and less predictable than rules. Keep a person on consequential decisions.
Ask in this order. Stop at the first yes.
Run each step of the process through these questions. The order matters: it keeps you from reaching for AI when something simpler and cheaper does the job.
Real work is a combination.
Two engagements where several technologies worked together — each doing the part it's best at.
See the technology mix for your own processes.
Every Digital Taskforce assessment classifies the recommended workforce by technology — and shows how little of it needs AI.
