Are production workflow failures becoming a real reliability problem?

I'm exploring a product idea and want honest feedback from people actually running automations in production.

The idea is FlowOps: a reliability layer for business automations/workflows.

The problem I'm investigating isn't the obvious:

It's the harder cases:

• The workflow says success, but 0 records actually reached the destination.
• A webhook silently stops arriving.
• An API/schema change breaks part of a workflow.
• Credentials expire and nobody notices.
• A scheduled workflow stops running.
• An automation keeps running but produces incorrect/incomplete business data.

The idea is that FlowOps would monitor these workflows from outside the automation platform, detect these silent failures/anomalies, and explain what went wrong.

For example:

n8n → “Execution successful ✅”

But FlowOps detects:

“37 leads expected → 0 reached CRM → likely schema/filter regression 🚨”

I'm trying to determine whether this is actually a problem worth paying to solve, or whether teams already have good enough solutions.

For people running production automations:

1. Have you experienced this kind of “workflow succeeded but business outcome failed” problem?

2. How do you detect it today?

3. What's the most expensive or painful automation failure you've experienced?

4. Would you pay for an external reliability/monitoring layer specifically for critical workflows? Why or why not?

I'm especially interested in experiences with n8n, Zapier, Make, Workato, custom integrations, CRM/data-sync pipelines, and AI-agent workflows.

I'm not promoting anything yet — I'm trying to figure out whether this is a real problem or a founder-created problem.
