What is a Cause and Effect Analysis?
A cause-and-effect analysis, also known as a Fishbone Diagram or Ishikawa Diagram, is a visual tool for systematically identifying and presenting all possible causes of a problem. It allows teams to study the root causes and effects of a situation.
It helps brainstorm, organise, and present the causes, facilitating a thorough investigation into the major factors at play.
9 Steps in Completing a Cause and Effect Analysis in the Workplace
- Identify the Problem: Clearly define the problem or effect to be analyzed. It should be specific, measurable, and written in a problem statement.
- Draw the Backbone: Draw a horizontal arrow pointing to the right, representing the ‘fish’s spine,’ and write the problem at the ‘fish’s head.’
- Identify the Major Cause Categories: Identify the major factors that could contribute to the problem. These are drawn as ‘bones’ off the spine. Common categories include People, Methods, Machines, Materials, Environment, and Measurements.
- Identify Possible Causes: For each major category, brainstorm possible causes. These are the ‘smaller bones’ attached to the major bones.
- Analyze and Group Causes: Group similar causes under more encompassing categories if necessary.
- Prioritize Causes: Rank the causes based on their impact and frequency. This helps in focusing on the most critical causes.
- Investigate the Root Cause: Dig deeper into the highest priority causes to find the root cause.
- Develop Action Plans: Develop strategies to address the root causes identified.
- Implement and Monitor: Implement the action plans and monitor the results, adjusting the plans as necessary.
