The Problem Most functional safety engineers eventually face project decisions where the standards don’t give a clear answer. Legacy systems. Architectural constraints. Incomplete failure data. Conflicting guidance between IEC 61508 and IEC 61511. Those decisions often get made alone. What Premium Members Get Premium membership is designed for engineers working through real project scenarios. Members receive access to: Peer Decision Review Sessions Fortnightly live sessions where members bring real engineering scenarios and work through the decision with experienced functional safety practitioners. Functional Safety Template Library A complete set of project-ready templates aligned with IEC 61511. Built for engineers delivering real safety lifecycle documentation. Engineering Tools Tools designed specifically for functional safety work including the SILVerify software and practical calculation resources. Founding Member Pricing Because the community is still growing, founding members can lock in the current price permanently. As the library grows and new tools are added, the price will increase. Founding members keep their original price. Upgrade now

SILVerify is back online with new features What's new: → Build your own approved failure rate library — access any device in one click on any future project → Integrated AI assistant for in-app support — answers questions from the user guide instantly If you do SIL verification under IEC 61508 or IEC 61511, it's worth a look. I'm really happy with this now, it's going to save me a lot of time, thanks for your patience, everyone → Sample project is now included — let me know what you all think, please 🙏 https://silverify.co.uk/

SILVerify is briefly offline today while I carry out some updates. What's been added: → Device library — a controlled register of failure rate data. Store your approved λD, DC, SFF, and SC values once, with a record of who verified the data and on what basis. One click fills any channel from your library on any future project. → Full 2oo3 and 1oo2 support across all three subsystems — sensors, logic solver, and final elements — with CCF assessment, beta factor derivation, and SC synthesis per IEC 61508 Clause 7.4.7. → In-app help page with an AI assistant that answers questions from the user guide. Back online later today. Will post to notify when it's live

Here’s everything that’s included: ✅ SILVerify — full access to the SIL verification software I built. Complete three-barrier IEC 61508 hardware SIL verification. PFDavg, architectural constraint (Route 1H), systematic capability. Professional Word report generated automatically. Built by a functional safety consultant, validated against IEC 61508-6 Annex B. — Before you upgrade, go to the free SILVerify classroom and have a look at: 📄 The User Guide — full walkthrough of SILVerify with a worked example 📋 The Sample Report — an actual output from the tool. Judge it for yourself. 🎥 Video walkthrough — coming very soon — Founder pricing is $30/month. This price exists because the community is early and I want the people who get in now to benefit from that. When it goes up — and it will — anyone already on $30 stays on $30. I won’t be announcing when the price changes. If you have questions before upgrading, post them below. Happy to answer anything. 👉 I'll be sending out login details to existing premium members over the course of the day - please bear with me

Over the past few months I’ve been building a tool to address a very specific problem in functional safety work: producing SIL verification reports. Most of us still follow roughly the same workflow: • Perform the calculations in Excel • Transfer the results into Word • Build tables and structure the report • Double-check every number matches the spreadsheet The engineering itself is usually straightforward — but the reporting can take several hours on a project with multiple SIFs. SILVerify is a web application designed to streamline that process while keeping the engineer firmly in control of the result. The tool performs the SIL verification calculations and structures the report automatically, but every intermediate value is visible so the engineer can review the result before issuing the report. Key principles behind the design: • No black-box calculations • Full transparency of intermediate values • Implementation of the three-barrier IEC 61508 verification approach• Structured, professional DOCX report generation • Clear statement of scope and assumptions The goal isn’t to replace engineering judgement — it’s to remove the mechanical work around it so the engineer can focus on reviewing and defending the calculation. I’ll be making the first version of SILVerify available tomorrow to Premium members of the Functional Safety Playbook community. Tomorrow I’ll post: • A short walkthrough of the tool• Example calculation outputs• A sample report generated from the system One small note: the current membership price is the early founding member price. As the tool and resources develop this will increase, but anyone who joins at the current price will keep that price for life. If you have any questions about the approach or the calculations, feel free to raise them in the comments.
