It consists of all the required production stages, inventory storage, WIPs and quality checks, including all the related information. This is to visualize the present state of the process. On the basis of the current state, improvement areas are identified and the future state of the business process is designed (a briefing is given in Figure 1.5). The Fishbone diagram is widely known as the cause–effect diagram. It can be a good starting point for the enterprises seeking for process improvement. The Fishbone diagram primarily identifies the possible root causes of the problem occurring at any stage of the production and logically eliminates them one by one to arrive at the real root cause of the problem. The Ishikawa diagram has been named after its originator Kaoru Ishikawa, the Japanese quality pioneer, and it has been used in multiple manufacturing industries because of its simplicity of usage [5]. The Fishbone diagram is not just a diagram but a way of brain-storming and finding the root cause. It is a methodology to systematically eliminate the less potential causes.
Four Basic Tools for Problem Solving

Our third tool, the cause-and-effect diagram, or fishbone diagram (because its structure resembles the bones of a fish), is one of the most popular tools ever developed. It was created and developed by Dr. Kaoru Ishikawa, a noted Japanese consultant, and is also referred to as the Ishikawa diagram in his honor. A cause-and-effect diagram is a tool that helps identify, organize, and display possible causes of a specific problem. It graphically illustrates the relationship between a given outcome (the effect) and all the factors that might influence the outcome (the causes). The structure of the diagram helps the team think in a very systematic way, as it looks for potential causes of the problem it is trying to solve. Figure 2.6 is a typical layout of a cause-and-effect diagram.
Incident Investigation or Root Cause Analysis
Published in Edgar Bradley, Reliability Engineering, 2016
Ishikawa diagrams (also called fishbone diagrams, herringbone diagrams or Fishikawa) are diagrams that show the possible causes of a specific event. Such a diagram is shown in Figure 5.2. Common uses of the Ishikawa diagram are product design and quality defect prevention, to identify potential factors causing an overall effect. Each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify these sources of variation. The categories typically include the following: People: Anyone involved with the process.Methods: How the process is performed and the specific requirements for doing it.Machines: Any equipment, computers, tools and so on required to accomplish the job.Materials: Raw materials, parts, pens, paper and so on used to produce the final product.Measurements: Data generated from the process that are used to evaluate its quality.Environment: The conditions, such as location, time and temperature, to name a few.

The concept of the cause and effect diagram originated in 1943 when Dr. Karou Ishikawa was explaining to engineers how factors can be sorted in an organized way (Ishikawa, 1991). The cause and effect diagram is also known as an Ishikawa diagram or a fishbone diagram. A problem is listed at the front of the cause and effect diagram, and then category labels are placed on the main branches. These are often machines, methods, environment, people, and materials. However, the exact label names can vary. Sub-branches are then listed with potential causes (Tague, 2005). The potential causes in the major and minor branches are created through brainstorming (Metha, 2014).

The objective of the analyze phase of a LSS DMAIC project is to identify the root causes of the problem. The first step towards this is a brainstorming session with all the stakeholders of the process to identify the potential causes for dimensional variation. These potential causes are usually presented in the form of an Ishikawa diagram or cause and effect diagram for further analysis and validation. Multiple brainstorming sessions were conducted to arrive at the cause and effect diagram for ‘Ball hole to NSS Dimension Not Ok’ (refer Figure 6).

Another way to visualize the problems and search for solutions is the Ishikawa diagram. One of the most significant challenges that the sector faces is about competition because the miners usually concentrate in the same region due to the mineral disposition in nature. Applying the Ishikawa diagram, it is possible to identify ways to make companies more competitive and better ways to manage their activities (Ilie and Ciocoiu, 2010). In Figure 5, it can be visualized the items to be analyzed using this technique.
