Fault Tree Analysis (FTA) is a top-down approach to failure analysis, starting with a potential undesirable event called a top event, and then determining all the ways in which it can occur. In other words, Fault Tree Analysis is a graphical representation of the logical structure displaying the relationship between an undesired potential event (top event) and all its probable causes. Based on the FTA, mitigation measures can be developed to minimize the probability of the undesired event.

Fault Tree development is easy with FTA-Pro™ software helping you run studies such as:
- Quantifying probability of top event occurrence
- Evaluating proposed system architecture attributes to establish hardware reliability budgets and Development Assurance Levels
- Assessing design modifications and identify areas requiring attention
- Complying with qualitative and quantitative safety/reliability objectives
- Qualitatively illustrate failure condition classification of a top-level event
- Establishing maintenance tasks and intervals from safety/reliability assessments

Addressing Your Industry’s Challenges
FTA-Pro can help improve maintenance programs, improve new designs, understand failure mechanisms and, ensure best efforts to prevent future occurrences. Though FTA-Pro is designed for the pre-construction of possible failure events and their expected results, you can also perform thorough analyses of post-event failures.
Applicable across a wide cross-section of global industries (including: aerospace, space, automotive, transportation, electronics, semiconductor, pharmaceutical, general manufacturing, chemical, oil & gas, petrochemical, defense, and IT), FTA-Pro helps you comply with:
|
|
- SAE ARP 4761
- SAE ARP 4754
|
- MIL-STD-882
- NUREG-0492
- and more
|
|
 |
With FTA-Pro, you can:
- Ensure compliance with safety and reliability requirements
- Reduce design defects, over-design, product recalls, and production downtime
- Increase reliability and confidence in calculated results
- Significantly increase your calculation speed - saving time and money
- Reduce Fault Tree (FT) development time
- View information graphically for rapid understanding
- Import files from Dyadem's leading Failure Mode and Effects Analysis application (FMEA-Pro® 7 and FMEA-Med™ 7)
- Employ solid FTA practices to help ensure that your products are safe, reliable, and of good quality

Companies using fault tree analysis as a principle part of their design and development operations typically save more time, resources, and expenditures than those that don’t do FTAs – especially in conjunction with good FMEA practices.
Potential faults such as design flaws and component failures can be reasonably predicted, thereby reducing the opportunities for in-market product failures, recalls, and other damage to your corporation’s reputation and revenues.
