Here’s an example of the 5 Whys in action:

1. Why did the machine stop?

• There was an overload and the fuse blew.

1. Why was there an overload?

• The bearing was not adequately lubricated.

1. Why was it not lubricated sufficiently?

• The lubrication pump was not pumping adequately.

1. Why was the pump not adequately pumping?

• The pump intake was clogged with debris.

1. Why was the intake clogged?

• There was no filter installed, and maintenance checks were infrequent.

This example demonstrates how each answer leads to the next question until the fundamental cause is identified.

Implementing Cause and Effect Analysis

Cause and effect analysis, also known as fishbone or Ishikawa diagram, is another effective technique used in identifying the root causes of an incident. It enables investigators to visually map out the causes of an incident across various categories such as methods, materials, equipment, and people.

A basic table format to collect data for a cause and effect analysis might look like this:

Category	Possible Cause
Methods	Inadequate training procedures
Materials	Use of substandard raw materials
