What are the three basic types of root causes?
What is root cause analysis? The three basic types of causes of a problem are physical, human and organisational e.g. a material item failed, someone made an error, a system, process or policy is faulty. Most problems in complex systems are made up of more than one single cause.

What are the root cause analysis tools?
Below we discuss five common root cause analysis tools, including: Pareto Chart. The 5 Whys. Fishbone Diagram….

What is a root cause example?
For example, a broken wrist hurts a lot but the painkillers will only take away the pain not cure the wrist; you’ll need a different treatment to help the bones to heal properly. In this example, the problem is a broken wrist, the symptom is pain in the wrist and the root cause is broken bones.
What is the immediate cause?
The final act in a series of provocations leading to a particular result or event, directly producing such result without the intervention of any further provocation.
What is direct cause?
A direct cause is the result of physical contact with an object or hazardous substance and is usually the result of one or more unsafe acts, unsafe conditions or both. These unsafe acts and/or conditions are indirect causes, or symptoms.
Why are fishbone diagrams drawn?
A cause and effect diagram, often called a “fishbone” diagram, can help in brainstorming to identify possible causes of a problem and in sorting ideas into useful categories. A fishbone diagram is a visual way to look at cause and effect.
