The accident analysis diagram example "Accident analytic tree" was redesigned from the picture 7-14 from the "DOE Workbook. Conducting Accident Investigations. Revision 2."
"Analytic tree analyses are well defined, useful methods that graphically depict, from beginning to end, the events and conditions preceding and immediately following an accident. An analytic tree is a means of organizing information that helps the investigator conduct a deductive analysis of any system (human, equipment, or environmental) to determine critical paths of success and failure. Results from this analysis identify the details and interrelationships that must be considered to prevent the oversights, errors, and omissions that lead to failures. In accident investigations, this type of analysis can consist of both failure paths and success paths, and can lead to neutral, negative, or positive conclusions regarding accident severity.
TIP.
An analytic tree enables the user to:
(1) Systematically identify the possible paths from events to outcome.
(2) Display a graphical record of the analytical process.
(3) Identify management system weaknesses and strengths."

Stakeholder Onion Diagrams
The Stakeholder Onion Diagram is often used as a way to view the relationships of stakeholders to a project goal. A basic Onion Diagram contains a rich information. It shows significance of stakeholders that will have has influence to the success achieve
AWS Architecture Diagrams
AWS Architecture Diagrams with powerful drawing tools and numerous predesigned Amazon icons and AWS simple icons is the best for creation the AWS Architecture Diagrams, describing the use of Amazon Web Services or Amazon Cloud Services, their application for development and implementation the systems running on the AWS infrastructure. The multifarious samples give you the good understanding of AWS platform, its structure, services, resources and features, wide opportunities, advantages and benefits from their use; solution’s templates are essential and helpful when designing, description and implementing the AWS infrastructure based systems. Use them in technical documentation, advertising and marketing materials, in specifications, presentation slides, whitepapers, datasheets, posters, etc.

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]
