The paper "Flow Chart, Root Cause Analysis, Event Tree, Decision Tree" is an outstanding example of a management literature review. Flow chart, root cause, event tree and decision tree are all risk assessment tools. Each of them has its advantages and disadvantages. The main similarity in each and every one of them is that they are crucial tools for simplifying the process of risk assessment through analyses of processes with the help of diagrams and symbols.   Flow chart Flow charts are simple diagrams that show how different steps in a process fit in together.

Flow charts are very effective tools for explaining how a process works as well as documenting the channels that should be followed in order for a certain task to be done. The main advantage of a flow chart is that when processes are being mapped out, one’ s understanding of these processes is clarified. During the clarification processes, some improvements can be made in the flow charts whenever they are deemed necessary. A flow chart can be a very effective tool for defining and analyzing the processes that are required for a certain function in a large organization to be performed.

In the local government, the different stages involved in the process can best be exemplified through the use of flow diagrams. A properly drawn flow chart should be used to derive analyses, communication and discussion. In this way, areas that need improvement can be defined and singled out for standardization purposes. Researchers are often comfortable while working out with complex structures with the help of flow charts. Without these risk assessment tools, a researcher may be overwhelmed by the complexity of the bigger picture.

The success of this research tool is hedged on the understanding of each of the meanings attached to the symbols used. Elongated circles represent the beginning or end of processes; rectangles represent actions or instructions; while diamonds represent decisions that have to be made by the person who is implementing the process. One of the most obvious limitations of a flow chart is that unlike an event tree, it gives the illusory impression that everything “ flows smoothly” .
