    • Mean Time Between Failure (MTBF),
    • Fault Tree Analysis (FTA),
    • Safety analyses,
    • And more.
  • Meet reliability requirements,
  • Improve product and system reliability,
  • Build reliability into new designs,
  • Produce software for calculating reliability (ask about incorporating our data!),
  • And more!

Engineers worldwide have been using the NPRD series for decades.

Testimonial From a Current ROADS Subscriber

“It is easy to access online from my computer even if I am working from home. The Search has drop-downs to suggest nouns for items to help determine a good description of exactly the item I may be looking for. It also works by just starting to type a word which makes it pretty quick to find the item in a search.

“The failure modes listed for an item provide us with more confidence [when] we have considered all aspects of failure within our FMECA. Dates provided on the source help us determine if the data is relevant to our similar item, same for the Environment and quality fields.” -Gail F., Current ROADS Subscriber.
