Changes include:What is Fishbone Diagram in 7 QC Tools  reverse fishbone diagram, process fishbone, time-delay fishbone, CEDAC (cause-and-effect diagram with the inclusion of cards), cause enumeration diagram, and time-delay fishbone.

What is Fishbone Diagram (Ishikawa Diagram) in 7 QC Tools

What is Fishbone Diagram in 7 QC Tools Among the seven fundamental quality tools is the cause analysis tool. The fishbone graphic shows a wide range of potential reasons why an impact or issue could exist. It is useful for organizing brainstorming sessions. Ideas are instantly sorted into helpful categories. Reason and Consequence Diagrams, commonly referred to as fishbone diagrams, are useful for determining the possible sources of an effect or an issue. Effective brainstorming not only helps organize ideas into categories, but it also identifies potential areas of growth.1.

When to use a fishbone diagram

What is Fishbone Diagram in 7 QC Tools By encouraging the team to look at the categories and examine other possible causes, a fishbone diagram can be useful in uncovering potential causes for an issue that might not otherwise be considered.

• When identifying the possible causes for a problem
• When a team’s thinking tends about defects to fall into ruts

Fishbone Diagram Procedures

Materials needed:- Pen for marking and a whiteboard or flipchart.

1-Decide on an effect (problem statement). In the upper right corner of the flipchart or whiteboard, write it. Draw an arrow pointing horizontally to it and enclose it in a box.

2-List all of the main categories that the issue could have. If you find this challenging, utilize general headings:

• Man
• Method
• Machine
• Materials
• Measurements
• Mother Nature

3-Write the categories of causes as branches from the main arrow.

4-List every potential reason for the issue. inquire “Why does this happen?” The facilitator notes each suggestion as a branch from the relevant category as it is made. If a cause is related to multiple categories, it may be written in multiple places.

5-Ask “Why does this happen?” regarding each factor once more. Write causes that branch out into sub-causes. Ask “Why?” again and again to uncover more profound levels of causation. Cause relationships are indicated by branch layers.

6-Pay close attention to areas of the chart with low or no ideas when the group runs out of them.

Fishbone Diagram Example

What is Fishbone Diagram in 7 QC Tools A production team created this fishbone graphic in an attempt to identify the cause of recurring iron contamination. The group generated ideas by using the six broad headings. Branches in layers demonstrate careful consideration of the root causes of the issue.

What is Fishbone Diagram in 7 QC Tools In the “materials of construction” idea under the name “Machines,” for instance, there are four different types of equipment followed by a few specific machine numbers. Take note that certain concepts are presented twice. “Calibration” appears under “Methods” as a contributing element to the analytical process and under “Measurement” as a potential source of laboratory error. When it comes to collecting samples, “iron tools” can be viewed as a “Methods” problem or a “Manpower” problem involving maintenance staff.

Create a Fishbone Diagram

What is Fishbone Diagram in 7 QC Tools Create a concise problem statement that the entire team can support. Give specifics regarding the problem’s cause and timing.

On the right side of your paper, write the problem statement at the top of the “fish.” Your group will solve this issue and move on. Draw an arrow-pointing line across the fish’s head, which serves as its “backbone.”

What is Fishbone Diagram in 7 QC Tools Utilize this straightforward, visual tool to examine process dispersion by starting with the fishbone diagram template. The major causes and contributing factors that result in an effect (symptom) are depicted in the ensuing diagram.

What is Fishbone Diagram in 7 QC Tools Tales of Fish (bone) (Quality Progress) The fishbone diagram’s methodology predates many of its applications. The authors examine how mind mapping might be used to greatly enhance the fishbone diagram, one of the seven fundamental quality tools, by digitizing it.
