How to Create a Fault Tree Analysis Diagram (FTD) in ConceptDraw PRO

Fault Tree Diagram are logic diagram that shows the state of an entire system in a relationship of the conditions of its elements. Fault Tree Diagram are used to analyze the probability of functional system failures and safety accidents. ConceptDraw PRO allows you to create professional Fault Tree Diagrams using the basic FTD symbols. An FTD visualize a model of the processes within a system that can lead to the unlikely event. A fault tree diagrams are created using standard logic symbols . The basic elements in a fault tree diagram are gates and events.
Root cause analysis (RCA) tree diagram lets identify the root causes for a factor and then list possible corrective action. The diagram displays the structure of causes for a factor and possible corrective actions. The root cause analysis tree diagram is used for further formulation of actions.
"Tree Diagram.
This tool is used to break down broad categories into finer and finer levels of detail. It can map levels of details of tasks that are required to accomplish a goal or solution or task. Developing the tree diagram helps one move their thinking from generalities to specifics." [Seven Management and Planning Tools. Wikipedia]

"Root cause analysis (RCA) is a method of problem solving that tries to identify the root causes of faults or problems.
RCA practice tries to solve problems by attempting to identify and correct the root causes of events, as opposed to simply addressing their symptoms. Focusing correction on root causes has the goal of preventing problem recurrence. RCFA (Root Cause Failure Analysis) recognizes that complete prevention of recurrence by one corrective action is not always possible.
Conversely, there may be several effective measures (methods) that address the root causes of a problem. Thus, RCA is an iterative process and a tool of continuous improvement.
RCA is typically used as a reactive method of identifying event(s) causes, revealing problems and solving them. Analysis is done after an event has occurred. Insights in RCA may make it useful as a preemptive method. In that event, RCA can be used to forecast or predict probable events even before they occur. While one follows the other, RCA is a completely separate process to Incident Management." [Root cause analysis. Wikipedia]

The vector stencils library "Fault tree analysis diagrams" contains 12 symbols for drawing Fault Tree Analysis (FTA) diagrams.
"Fault tree analysis (FTA) is a top down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. This analysis method is mainly used in the fields of safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk or to determine (or get a feeling for) event rates of a safety accident or a particular system level (functional) failure. FTA is used in the aerospace, nuclear power, chemical and process, pharmaceutical, petrochemical and other high-hazard industries; but is also used in fields as diverse as risk factor identification relating to social service system failure.
In aerospace, the more general term "system Failure Condition" is used for the "undesired state" / Top event of the fault tree. These conditions are classified by the severity of their effects. The most severe conditions require the most extensive fault tree analysis. These "system Failure Conditions" and their classification are often previously determined in the functional Hazard analysis." [Fault tree analysis. Wikipedia]

It is also convenient to have professional looking Fault Tree Analysis example before the eyes, and it is excellent that this solution includes large collection of such examples.
"A root cause is an initiating cause of a causal chain which leads to an outcome or effect of interest. Commonly, root cause is used to describe the depth in the causal chain where an intervention could reasonably be implemented to change performance and prevent an undesirable outcome." [Root cause. Wikipedia]
"Problem-solving consists of using generic or ad hoc methods, in an orderly manner, for finding solutions to problems. Some of the problem-solving techniques developed and used in artificial intelligence, computer science, engineering, mathematics, medicine, etc. are related to mental problem-solving techniques studied in psychology."

"Failure analysis is the process of collecting and analyzing data to determine the cause of a failure. It is an important discipline in many branches of manufacturing industry, such as the electronics industry, where it is a vital tool used in the development of new products and for the improvement of existing products. There are many companies which provide services to find the cause of failure in products, devices and in post disaster situations. The failure analysis process relies on collecting failed components for subsequent examination of the cause or causes of failure using a wide array of methods, especially microscopy and spectroscopy. The NDT or nondestructive testing methods (such as Industrial computed tomography scanning) are valuable because the failed products are unaffected by analysis, so inspection always starts using these methods."

"Another way of assessing hazards is using fault tree analysis. In this process, each of the identified hazards is covered by a detailed analysis to find out what might cause it. Either inductive or deductive reasoning is applied. In the case of software hazards, the usual focus is to determine faults that will cause the system to fail to deliver a system service, such as a monitoring system. A "fault tree" is constructed to link all the possible situations together, to help identify the interrelationships of the failures, which modules may cause them, and what "trickle-down effects" there might be. Here is an example of a fault tree, as applied to the Insulin delivery system from Sommerville...
Note that this tree is only partially complete, since only the potential software faults are shown on the diagram. The potential failures involving hardware, such as low battery, blood monitor or sensor failure, patient over-exertion or inattention, or medical staff failure are noticeable by their absence.
The fault tree and safety specification processes are two ways of helping with system risk assessment tasks. Once the risks are identified, there are other assessments that need to take place. First, the likelihood of the risk occurrance must be assessed. This is often quantifiable, so numbers may be assigned based on things like MTBF, latency effects, and other known entities. There may be other non-quantifiable contributors to the risk likelihood, however, such that these must be assessed and estimated by experts in the domain. (Don't short-change this process when dealing with critical systems!) Finally, the risk assessment must include the severity of the risk, meaning an estimation of the cost to the project in the event the risk item actually does occur. "Cost to the project" means all associated costs, including schedule delays, human injury, damage to hardware, corruption of data, and so on."

How To Create Root Cause Analysis Diagram Using ConceptDraw Office

Root Cause Analysis (RCA) is used to determine the main causes of the problem. If the certain factor is the root cause, this mean that its vanishing will help to prevent the further recurrence of the problem. Root Cause Analysis diagram is used to analyze the root causes of factors that influence the problem. It helps to identify the root causes for a factor and then propose possible corrective actions. A diagram is constructed separately for each high priority factor. The ability to create a RCA tree diagram from a mind map is supported by the ConceptDraw Seven Management and Planning Tools solution.
