Business Analysis, identifying the underlying causes of problems or issues is a crucial task. Without a structured approach to root cause analysis, it's easy to misdiagnose problems, leading to ineffective solutions and wasted resources. One powerful tool that business analysts rely on is the Fishbone Diagram, also known as the Ishikawa or Cause-and-Effect Diagram. This visual representation enables professionals to dig deep into the underlying causes of an issue, making it easier to implement effective solutions. In this blog post, we will explore Fishbone Diagrams and the broader concept of root cause analysis in the context of
Business Analysis Techniques.

The Significance of Root Cause Analysis in Business Analysis
An essential component of the business analysis process is root cause analysis. It entails organising to find and treat problems' root causes instead of just treating their symptoms. This approach helps businesses not only fix issues but also prevent them from happening again, which eventually boosts productivity, lowers expenses and improves overall performance.
Introducing the Fishbone Diagram
One useful tool that makes the root cause analysis process easier is a fishbone diagram. Because of its originator, Japanese quality control specialist Kaoru Ishikawa, it was first created and is often referred to as an Ishikawa Diagram. Because of how it is shaped, the diagram is called "Fishbone" because it resembles the skeleton of a fish.

Because it breaks complicated problems down into its component elements, the Fishbone Diagram promotes collaborative problem-solving, which makes it especially helpful for group discussions. It is a graphic depiction that links many possible causes (the fish's bones) to an issue (the fish's head). Usually, the primary reasons are identified as branches that emanate from the fishbone's spine. Depending on the particular problem, these categories may differ, but they often include components like people, procedures, tools, supplies, and environments.
Creating a Fishbone Diagram
To make a Fishbone Diagram, you should do the following:
- Define the problem: Begin by stating the issue or problem you're attempting to solve in plain English. Put it at the top of the fishbone as a brief statement.
- Identify major categories: Determine the main groups or elements that could be causing the issue. From the spine, these categories will create the "bones" of the fish.
- Brainstorm causes: Under each area, discuss possible reasons in a group setting. Promote candid conversations and consider all options, even if they appear improbable. This is when the diagram's collaborative quality shows through since it encourages various opinions and perspectives.
- Analyse and prioritise: Once the possible reasons have been listed, assess each one and rank them according to how likely they may aggravate the issue. This stage assists in concentrating your attention on the most important variables.
- Identify root causes: Until you reach the core reasons, keep going deeper and more fundamentally into the causes that have been found. When they are taken care of, the problem will be resolved with the greatest influence.
Real-World Application
To demonstrate the use of Fishbone Diagrams in business analysis, let's look at a real-world scenario. Consider a manufacturing business that notices an abrupt rise in product failures. To raise the calibre of its output, the corporation seeks to determine the underlying reasons for this quality problem and put remedial measures in place.
One such issue statement for the Fishbone Diagram might be "Increased Product Defects." The primary divisions that emanate from the fishbone's spine may include "Processes," "Materials," "Equipment," and "Human Factors."
The team members discuss probable reasons under each category. They may list problems like "Inadequate Training," "Inefficient Quality Control," and "Variability in Manufacturing" under "Processes." They might include "Supplier Quality" and "Raw Material Specifications" under the "Materials" category. Similarly, "Machine Maintenance" and "Calibration" under "Equipment" might be contributing factors. Finally, they can come across problems like "Lack of Standard Operating Procedures" and "Employee Fatigue" in the "Human Factors" category.
Conclusion
Fishbone diagrams are an essential tool in the toolbox of business analysis methodologies, enabling analysts to identify the underlying causes of complicated problems. Fishbone Diagrams support efficient problem-solving and the long-term enhancement of procedures and goods by encouraging teamwork, offering an organised method, and directing groups to concentrate on the issue's core. Business analysts will find this approach to be an invaluable resource as it can effectively handle and avoid difficulties in a wide range of businesses and sectors when used appropriately.
