Functional Safety Play Book

The grey areas in IEC 61508 and IEC 61511 turn into pressure when decisions affect schedule and cost.

Most functional safety engineers face situations where the standards don't give a clear answer.

Rejecting a design. Challenging a SIL claim. Explaining why something might work — but isn't safe enough.

And often you're making those calls alone.

The Playbook is a community for engineers who want a confidence check from experienced practitioners when it matters.

🔵 Decision Reviews — bring a real scenario, get experienced input

💬 Peer discussions with working engineers

📋 Premium tools — FSMS, proof test procedures, SIL verification

Premium: $30/month founding price.

About me: 20 years in nuclear. Exida CFSE. TÜV certified. Still learning — but with enough scars to make the conversations interesting.
