Root Cause Analysis Series: Fishbone Diagram

Developing a corporate website often requires collaboration across multiple departments—Marketing, PR, Investor Relations, and IT. Without proper coordination, delays in content delivery or feedback are common and can impact project timelines and resources.

One effective tool to address this issue is the Fishbone Diagram, also known as the Ishikawa Diagram. It’s a root cause analysis method that can be applied directly to website development challenges.

 

What is a Fishbone Diagram?

A Fishbone Diagram helps teams systematically identify potential causes of a problem by illustrating the relationship between contributing factors in a visual “fishbone” structure. The diagram’s “head” represents the main problem, while the “bones” branch into key categories such as People, Process, Technology, Data, Environment, and Management.

This method was developed by Japanese quality control expert Kaoru Ishikawa and has since become widely used across industries to support quality improvement and project management.

 

Applying the Fishbone Diagram to Corporate Website Projects

Step 1: Define the Core Problem

Problem: “Delays in corporate website development due to untimely data submission and feedback.”

This is placed at the “head” of the fish.

 

Step 2: Identify Key Cause Categories

For this scenario, the main categories are:

- People

- Process

- Communication

- Management 

 

Step 3: Drill Down into Sub-Causes

People

- Core team members are too busy to provide input

- No clearly assigned point person within each department

Process

- No shared timeline that all teams align with

- Multi-layered, redundant approval steps

Communication

- Too many disconnected communication channels

- No centralized system to track feedback status

Management

- Lack of a single project owner overseeing coordination

- Inconsistent project status meetings

 

Step 4: Synthesize and Identify Root Causes

- The analysis points to two root causes:

- Lack of centralized project ownership

- Unstructured communication and task tracking processes

 

When to Use a Fishbone Diagram

This tool is ideal for:

- Cross-functional projects involving multiple teams

- Recurring issues where root causes are unclear

- Workflow analysis to inform process improvements

 

By breaking down complex problems into structured components, the Fishbone Diagram enables deeper insight into root causes and helps design more targeted solutions. It’s a vital tool for improving project efficiency—especially in digital product development and project management.
