We have multiple triggers across related objects, each handling a specific requirement. Individually they work as expected, but together they sometimes produce inconsistent results. Debugging feels difficult because execution order isn’t obvious. I want to understand why trigger behavior becomes unpredictable at scale?!
Salesforce does not guarantee execution order between multiple triggers on different objects. When one trigger updates another object, it can cause that object’s triggers and automation to fire, sometimes recursively. This creates execution paths that are difficult to reason about just by reading code.
The unpredictability increases when triggers perform updates without guarding against recursion or checking whether changes are actually required.
Most mature orgs solve this by using trigger handler frameworks, enforcing single-trigger-per-object patterns, and minimizing cross-object updates in synchronous transactions.
Takeaway: Trigger behavior becomes unstable when execution order is assumed rather than controlled.
