The Diagrama De Ishikawa, also known as the Ishikawa Diagram or Fishbone Diagram, is a visual tool used in various industries to identify and analyze the root causes of a problem. Developed by the Japanese quality control expert Kaoru Ishikawa in the 1960s, this diagram provides a systematic approach to problem-solving and quality improvement.


The Diagrama De Ishikawa is named after its resemblance to a fishbone, with the problem stated at the head of the diagram and the potential causes branching out as bones. It is a cause-and-effect analysis tool that helps teams understand the relationships between different factors contributing to an issue. By visually displaying the potential causes, it enables the identification and prioritization of the most influential factors.


One of the main advantages of the Diagrama De Ishikawa is its simplicity and ease of use. It facilitates collective brainstorming sessions and encourages collaboration among members of a team. By involving the entire team, it promotes a shared understanding of the problem, fostering a sense of ownership and commitment to finding a solution.

Additionally, the Diagrama De Ishikawa provides a structured approach to problem-solving. It categorizes potential causes into specific groups, such as people, process, equipment, materials, and environment. This categorization ensures comprehensive analysis and helps prevent overlooking any significant contributing factors.

Furthermore, this diagram helps in identifying the primary causes of a problem. By visually representing the cause-and-effect relationships, it enables teams to focus on the most influential factors rather than wasting time on minor details. This targeted approach increases the efficiency of problem-solving efforts.


The Diagrama De Ishikawa finds applications across a wide range of industries and disciplines, including manufacturing, healthcare, software development, project management, and quality control. It is particularly useful in situations where the complexity of a problem requires a systematic approach to identify its causes.

In manufacturing, for example, the Diagrama De Ishikawa can be used to identify the root causes of product defects, such as machine malfunctions, incorrect processes, or human errors. This allows for targeted improvements in quality control and process optimization.

In software development, the Diagrama De Ishikawa can help identify the causes of software bugs, system failures, or performance issues. By examining factors such as coding errors, inadequate testing processes, or hardware limitations, development teams can implement corrective measures to enhance the overall quality and reliability of their software products.

In project management, the Diagrama De Ishikawa can be applied to identify potential causes of project delays, cost overruns, or communication breakdowns. It allows project managers to address these issues proactively, minimizing their impact on the project’s success.


The Diagrama De Ishikawa is a valuable tool for analyzing complex problems and understanding their root causes. Its simplicity, ability to facilitate collaboration, and focused approach to problem-solving make it a widely used technique in various industries. By using this diagram, teams can gain valuable insights into the factors contributing to a problem and take appropriate actions to resolve it.
