In 1960s, Professor Kaoru Ishikawa has introduced Ishikawa diagram. This diagram also called fishbone diagram or cause and effect diagram (Ishikawa 1976). Since this diagram is inception, it has gained tremendous of popularity to identify the root cause of the variety of problems (Hossen et al. 2017). Besides that, Ishikawa diagram often called as fishbone diagram is because it can help in the brainstorming to determine the possible cause of a problem and also sort the ideas into the useful categories. Thus, this diagram is more structured approach than some other tools available for brainstorming the causes of a problem (Khilyuk & Chilingar, 2017).

Advantages of Ishikawa Diagram:
• Stimulate problem solving. Ishikawa diagram can clearly shows the reasons in the visual graph and explore the root causes that may stimulate the organization to find out the possible solution to the problems (Fahad 2017).
• Facilitate brainstorming. Ishikawa diagram is the best way to boost the structure brainstorming about the reason for the certain results and outcomes due to it can capture all the causes and effects (Hossen et al., 2017).
• Show all causes simultaneously. Those causes featured on the Ishikawa diagram can lead to the problem. Ishikawa diagram can illustrate each and every single possible of reason in the particular of diagram, which can beneficial for the in-depth analysis. Thus, this diagram can make as a useful tool for presenting the problem and solutions to the stakeholders (Karen …show more content…
Ishikawa diagram can keep the organization’s team more focus during the discussion while the team also understand what should be done to solve the issues for achieve the common goal.

Disadvantages of Ishikawa Diagram:
• Waste effort. Ishikawa diagram will make the teams feel waste of efforts in identifying the causes which have little effect on the issues (Li & Zhang, 2017).
• Opinion. Ishikawa diagram is mostly based on the opinion rather than evidence. This is because the process that are involved in a democratic way of selecting the cause. For example, to vote down the causes which may not an effective ways to identify the causes (Hossen et al., 2017).
• No proper discussion. If the team of the organization are using Ishikawa diagram as their discussion tools, they must be discussed properly if not it may deviate from the objectives (Khilyuk & Chilingar, 2017).
• Arrangement of root cause. Ishikawa diagram does not single out the root cause of the problem. This is because all the causes that listed on the diagram look equally important (EdrawMax
