Think of these top level events an extremely undesirable event — perhaps harm to your customer or some other loss of a mission critical feature. The Fault Tree Analysis then results in an actual tree diagram showing the relationship between the top level event and the lower level fault conditions. The fault tree analysis is able to define that relationship using logic gates, which allow you to estimate the overall reliability or likelihood of occurrence for the top level event.
This likelihood of occurrence can be paired with the severity of the top level event to calculate the risk associated with that event. To estimate the overall reliability for the top level event being analyzed, you must understand the relationship between the lower level fault conditions. Do multiple faults have to occur before the high level event occurs?
Or does only one of the lower level fault conditions have to occur before the high level event harm happens. The OR Gate captures the type of relationship where any of the lower level causes or events can result in the top level event. Using the FTA above, this symbol can be interpreted like this: An email server is down for more than 4 hours if there is a hardware failure OR a loss of power. The Loss of power only occurs if there is a power supply failure AND there is no spare.
The power supply failure is caused by a clogged filter. Below you can see that the top level critical event only occurs IF all of the conditions below it occur:. The reliability of these lower level events, i. With the OR gates, where any lower level fault can result in the top level event, where each lower level has fault has. This section was dedicated to three different Risk Management Tools , which include:.
The FMECA was next, where we discussed the criticality analysis matrix , including how to construct and interpret that matrix. Were you able to remember as much as you thought you could?

This is assessing the level of risk for your business premises or workplace environment with regard to those potential hazards. With all the risks that are out there, a risk matrix can be an easy way to assess the risk. The Risk Matrix is an incredible tool for quickly calculating the risk of a project. It helps identify what could go wrong likelihood and how much damage it would cause if these outcomes occurred severity.
This makes prioritizing issues quick and simple so you know which ones need attention. In order to ensure that risks are eliminated as much as possible, it is important for any potential hazards or dangers to be identified and evaluated.
This will help determine the best way of handling them — whether by eliminating their source completely or controlling how they affect people most at risk e. Ask these questions:. Can I get rid of this hazard altogether? If not, can I at least find a way to make it less hazardous?

One of the hazards they found was that some employees were not wearing any gloves. These can create huge risks if the employees are the cooks in the kitchen. Make Restaurant Feasibility Study in Excel! As with every report, you can create your risk assessment report simply with a pen and paper.
However, identifying and detecting the hazards, deciding on the severity of the danger, and recommending action and on top of that, writing every little detail down on a piece of paper by hand is hard work. It is time-consuming, tiring, and complicated to organize. Integrum: One of the programs you can use to create your report is Integrum. This is one of the most comprehensive tools in the market which is designed to optimize your business performance.
It makes identification very complete with a proper reporting system. So that you can create many dashboards, reports, and graphical analysis. Cura: CURA is a web-based risk management solution that provides flexible identification and monitoring. Visual dashboards, surveys, a self-assessment portal, notifications, workflow management designed to help you understand the impact that your company encounters.
Word: The other software you can use is Microsoft Word. It is the simplest option compared to the other programs. You could create tables, write the data in, and print it; however, Microsoft Word is not built for the process of creating a report.
You would be responsible for every letter of the data you enter and every table would be up to you to create and fill in.
We have an option better than that. Microsoft Excel is another great solution in order to create your risk assessment report. Because Excel is a software which we are all familiar with and we do not have to learn it from scratch. Our Risk Assessment Excel Template is designed to help you manage and control all the potential hazards that your company may have.
There is no learning curve. You will be confident that if you use our template in Excel while creating your report. Your tables for the report are already created and ready for you to fill in your data. It is designed not only with an easy to use a text-based design but also including a visual dashboard view for you.
Unlike other software packages and programs, Risk Assessment Excel Template provides two beneficial features: Dashboard and the Risk Assessment Matrix.
