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.
