Articles
Longer-form writing on PLM, RAMS, and digital engineering.
Practical, depth-first articles drawn from real engineering programs. New articles are added as topics are researched and written, there is no publication schedule.
Same MTBF, three different products
Ten failures in a thousand hours is an MTBF of 100 hours whether they arrive in the first afternoon, at a steady drip, or all at once at end of life. Those are three different products, and one number cannot tell them apart.
Redundancy on paper, single point in the rack
Two blocks in parallel multiply to a beautiful number. The cabinet they live in often has one power feed, one cooling path and one maintainer. What the block diagram cannot see, and how to put a number on it.
What a reliability prediction is actually for
The predicted MTBF will not match the fleet, and it was never supposed to. What the handbooks actually model, why they disagree with each other, and the questions that make a prediction defensible.
Reading a fault tree like an auditor
A fault tree is an argument dressed as arithmetic. How to read someone else's tree the way an assessor does, top event first, gates as claims, common causes hunted, and every number asked where it came from.
Derating: the cheapest reliability you will ever buy
Run a part below its ratings and the failure mechanisms inside it slow down, no redundancy, no new technology, just margin chosen at design time. How derating works, where it pays most, and when it stops being free.
AI in RAMS analysis: where it helps, and where it must not decide
A practitioner's map of AI in reliability, safety and maintainability work, the tasks it genuinely accelerates, the decisions that stay with the engineer, and the guardrails that keep a safety case defensible.
One model, many methods: why RAMS analyses must be connected
Allocation, prediction, FMECA, fault trees, maintainability, FRACAS, every RAMS method consumes what another produces. Run them disconnected and the numbers drift; connect them and the safety case stays alive.
RAMS meets requirements: why ALM integration matters
MTBF targets, tolerable hazard rates and safety goals are requirements before they are analyses. Connecting the RAMS toolchain to DOORS, Codebeamer or Jama turns compliance from an assembly job into a living trace.
Why your RAMS tool must talk to PLM and ERP
The BOM is the spine of every reliability analysis, and it lives in your PLM and ERP systems, not in your RAMS tool. Integration is what keeps the safety case pointed at the product you are actually building.
