Fault Tree Diagram Software, Create Fault Tree Diagrams Rapidly with Examples and Templates.
Create professional-looking Fault Tree diagram from examples and templates with Edraw.
Understand what is likely to happen in the future is prerequisite to make wise
plans and decisions. Designers and analysts have to make better-informed risk
assessment decisions based on evaluations of the risks and results related with
alternative designs and other risk-mitigating actions.
Fault Tree Analysis can
help address the ways of undesirable events could occur by providing you with
data showing how and under what circumstances the catastrophic failure or
hazards could occur. it is a graphical representation of the major faults or
critical failures associated with a product, the causes for the faults, and
potential countermeasures. The tool helps to identify areas of concern for new
product design or for improvement of existing products. It also helps users
identify corrective actions to correct or mitigate problems.
Fault Tree Diagram Software
Edraw Max is a vector-based diagramming software
with rich examples and templates. It is easy to create fault tree diagrams to
document business processes. Create diagrams that document events that might lead to
failure so that failures can be prevented.

Fault Tree DiagramExamples
Suppose that we visit the courthouse in a certain town, and we observe people
who stop at the office of the local justice of the peace to register their
marriages. Let A be the independent probability of finding in the office an
adult woman who is going to get married (i.e., female spouse), while B is
the probability of finding a marrying adult man (i.e., male spouse). We
disregard any liaison between staff members who are employed in that office
in order to be free of bias in our experiment.
The following fault tree diagram was created and included
in the Edraw example gallery.

Fault Tree Analysis Software. Then you can use the built-in
Fault Tree templates to create and present your business process with ease and
- Select a component for analysis. Draw a box at the top of the
diagram and list the component inside.
- Identify critical failures or "faults" related to the component.
Using Failure Mode and Effect Analysis is a good way to identify faults
during quality planning. For quality improvement, faults may be
identified through Brainstorming or as the output of
Cause and Effect Diagram.
- Identify causes for each fault. List all applicable causes for
faults in ovals below the fault. Connect the ovals to the appropriate
- Work toward a root cause. Continue identifying causes for each fault
until you reach a root or controllable cause.
- Identify countermeasures for each root cause. Use Brainstorming or a
modified version of Force Field Analysis to develop actions to
counteract the root cause of each critical failure. Create boxes for
each countermeasure, draw the boxes below the appropriate root cause,
and link the countermeasure and cause.
When to use Fault Tree Analysis
Fault tree analysis is useful both in designing new products/services or in
dealing with identified problems in existing products/services. In the
quality planning process, the analysis can be used to optimize process
features and goals and to design for critical factors and human errors. As
part of process improvement, it can be used to help identify root causes of
trouble and to design remedies and countermeasures.
