What usually breaks first when task automation goes wrong?

I’ve been working on a small side project that coordinates task execution

(deploy steps, scripts, AI-generated plans, etc.) and it made me realize

how often things fail simply because tasks run in the wrong order.

Before I go further, I’m trying to understand this from other builders:

• When automation fails for you, what’s the first thing that breaks?

• Is it missing dependencies, partial failures, retries, or human error?

• At what point do you stop trusting automation and step in manually?

Not looking to pitch anything — genuinely curious how others think about

this problem and where the real pain actually is.
