What is a significant disadvantage of the Ishikawa model?

The significant disadvantage of the Ishikawa model, which is often represented as a fishbone diagram, is that it does not provide a solution. The primary purpose of this model is to help identify the root causes of a problem by categorizing potential factors contributing to it. While it is effective in visualizing and organizing causes, the model itself does not include steps to solve these identified problems. This means that, after the analysis is complete, further action must be taken by the team to determine solutions based on the insights gained from the model.

Other options may suggest limitations or constraints regarding team involvement or the applicability of the model to various team sizes, but they do not reflect the core limitation of the model itself. It is critical for users of the Ishikawa model to be aware of this aspect, as the identification of root causes must be followed by a structured problem-solving approach to achieve effective outcomes.
