Understanding Automation in Salesforce
Apex Classes, Triggers & Flows Explained
Understand your Salesforce automation in plain business terms — without reading code.
Salesforce orgs accumulate automation logic over years — built up through Apex classes, triggers, and Flows. Apex is powerful and expressive, but it requires specialist knowledge to interpret. Most admins, analysts, and business stakeholders are not Apex developers, yet they need to understand what the automation is doing in order to make confident decisions. This article explains what the Automation Explainer does and how it bridges that gap.
The Challenge: Apex Requires Specialist Knowledge
Apex classes, triggers, and Flows control critical business behaviour — how records are created, how fields get their values, and how processes are triggered. Because Apex is written by developers, most of the people who need to make decisions about the system — admins, analysts, and business stakeholders — have to rely on developers or architects to answer questions like:
What is this Apex class or trigger actually doing — in plain business terms?
What automation will fire if I change this field or update this record?
Where is this field getting its value from?
What's the full chain of events triggered by this trigger or flow?
Without a way to bridge that gap, teams face slow incident resolution, heavy reliance on a small number of specialist engineers or external consultants, and increased risk when making changes. Getting answers today typically means opening code directly, jumping between tools, and depending on institutional knowledge that may not be documented anywhere.
What the Automation Explainer Does
When you click on any Apex class, Apex trigger, or Flow in Elements, the Automation Explainer generates a structured, plain-language explanation of what that automation does, how it fits into the broader system, and what the risk is if you change it.
It does not summarise in isolation. It traces the full automation chain — from root invocation through to downstream effects — and explains each part in business terms.
Key Capabilities
1. Purpose
A plain-language explanation of why this automation exists in business terms — what problem it was built to solve and what business outcome it produces.
2. When It Runs
All known invocation paths for the automation — direct and indirect. This includes triggers from buttons, page layouts, platform events, and other automations. Where invocation paths cannot be determined from static analysis alone, the explainer is transparent about the limits of its confidence.
3. What It Touches and Invokes
The fields and objects the automation reads or writes, and any downstream automations it calls. Understand the full blast radius before making a change.
4. Larger Process Context
How the selected automation fits into the end-to-end chain — from root trigger to final outcome. The explainer summarises the logic of all automations in the chain, not just the one you clicked on.
5. Why It's Risky
An assessment of the risk associated with changing or removing this automation — including complexity, coupling to other parts of the system, and execution frequency. Helps you prioritise what to investigate before making changes.
6. Confidence Score
A score that tells you how certain the analysis is, and why. Where Salesforce metadata limits full visibility — for example, dynamic references or runtime-only invocation paths — the explainer flags this explicitly so you know where to verify manually.
