Fishbone Analysis, also known as the Ishikawa Diagram or Cause-and-Effect Diagram, is a widely-used problem-solving tool that helps identify the potential causes of a specific problem or effect.
The key features of Fishbone Analysis are:
- Graphical Representation:
The analysis is displayed in the form of a diagram that resembles the skeleton of a fish, with the problem or effect as the “head” and the potential causes as the “bones” or “branches” of the diagram. - Categorization of Causes:
The potential causes are organized into major categories or main “bones” of the diagram. Common categories include Materials, Methods, Machines, Measurements, Environment, and People (also known as the 6M’s). - Structured Brainstorming:
The process involves a structured brainstorming session where a team identifies and lists all the possible causes that could contribute to the problem or effect. - Identification of Root Causes:
By breaking down the problem into its potential causes, the Fishbone Diagram helps uncover the underlying or root causes, rather than just addressing the obvious or surface-level symptoms.
Benefits of Fishbone Analysis:
- Facilitates Collaborative Problem-Solving: The process encourages team participation and diverse perspectives, leading to more comprehensive solutions.
- Provides Visual Clarity: The graphical representation makes it easier to understand the relationships between different factors and visualize the potential causes.
- Supports Continuous Improvement: The Fishbone Diagram can be revisited and updated as new information or solutions emerge, enabling ongoing improvement efforts.
- Identifies Root Causes: By focusing on the underlying causes, the analysis helps organizations address problems more effectively, rather than just treating the symptoms.
The Fishbone Analysis process typically involves the following steps:
- Define the problem or effect to be analyzed.
- Identify the main categories of causes (e.g., 6M’s).
- Brainstorm and list potential causes under each category.
- Organize the causes on the Fishbone Diagram.
- Analyze the diagram to identify the most significant or likely causes.
- Develop action plans to address the identified root causes.
By applying Fishbone Analysis, organizations can systematically explore the potential causes of a problem, leading to more effective and sustainable solutions.
Fishbone Analysis Example
The example depicts a comprehensive Fishbone diagram highlighting the potential causes contributing to the challenges faced in a software development project. This structured analysis tool, also known as the Ishikawa diagram, provides a valuable framework for identifying and addressing the underlying issues that can impact the success of a software project.
Key Factors Explored
The Fishbone diagram in the image covers five main categories: Quality, Budget, Scope, Schedule, and Listening. Within each of these categories, the diagram identifies specific factors that can influence the overall project outcomes.
Quality Factors:
- Defect rate excessive
- Customer not satisfied with product
Budget Factors:
- High staff turnover
- Need for additional cost
- Fluctuation of hardware cost
Scope Factors:
- Scope creep
- Features with low value
- Legacy code lack documentation
- High coupling
- Duplicated modules
Schedule Factors:
- Schedule slips
- Misunderstanding of business
- Communication breakdown
Listening Factors:
- Fear of change
- Not user-friendly enough
- Not mobile friendly
Action Plan
Based on the Fishbone diagram provided, here is a proposed action plan in a tabular format to address the challenges faced in the software development project:

– Project Management Office
– Continuous Improvement Team |
Ongoing |
This table provides a detailed action plan with specific objectives, responsible parties, and timelines for addressing the challenges identified in the Fishbone diagram. By breaking down the action items into these categories, the project team can effectively prioritize and manage the implementation of the improvement strategies.
Key aspects of this action plan include:
- Addressing quality, budget, scope, scheduling, and user-centric factors through targeted initiatives.
- Assigning clear responsibilities to cross-functional team members for effective collaboration.
- Defining realistic timelines for the implementation of each action item.
- Incorporating a continuous improvement approach to monitor progress and adapt the plan as needed.
By implementing this comprehensive action plan, the software development project team can work towards resolving the identified challenges and improving the overall project outcomes.
Tips and Tricks for Effective Fishbone Analysis
- Involve cross-functional team members: Bring together stakeholders from various disciplines (e.g., developers, project managers, testers, business analysts) to capture diverse perspectives and insights.
- Use brainstorming techniques: Encourage open and collaborative discussions to generate a comprehensive list of potential causes.
- Prioritize the causes: Assess the relative importance and impact of each cause to focus on the most critical areas.
- Continuously review and update: Regularly revisit the Fishbone diagram to monitor progress, identify new challenges, and adapt the action plans accordingly.
- Communicate and implement solutions: Ensure that the identified solutions are effectively communicated and implemented across the project team and organization.
Conclusion
By applying Fishbone analysis to the software development project challenges depicted in the diagram, project teams can systematically identify and address the root causes of their issues. This structured approach empowers organizations to enhance project quality, manage budgets effectively, optimize scope, improve schedules, and foster better communication and collaboration – ultimately leading to more successful software development outcomes.
