Ishikawa's Message Ishikawa's biggest contribution is in simplifying statistical techniques for quality control in industry. At the simplest technical level, his work has emphasised good data collection and presentation, the use of Pareto Diagrams to prioritise quality improvements and Ishikawa Diagrams.
Ishikawa sees the Cause-and-Effect Diagram (or Ishikawa Diagram), like other tools, as a device to assist groups or quality circles in quality improvement. As such, he emphasises open group communication as critical to the construction of the diagrams. Ishikawa diagrams are useful as systematic tools for finding, sorting out and documenting the causes of variation of quality in production and organising mutual relationships between them. Other techniques Ishikawa has emphasised include the seven Quality Control tools.
Other than technical contributions to quality, Ishikawa is associated with the Company-wide Quality Control (CWQC) Movement that started in Japan during the period 1955--60 following the visits of Deming and Juran. Ishikawa sees the CWQC as implying that quality does not only mean the quality of product, but also of after sales service, quality of management, the company itself and the human life. The outcomes of such an approach are:
1. Product quality is improved and becomes uniform. Defects are reduced.
2. Reliability of goods is improved.
3. Cost is reduced.
4. Quantity of production is increased, and it becomes possible to make rational production schedules.
5. Wasteful work and rework are reduced.
6. Technique is established and improved.
7. Expenses for inspection and testing are reduced.
8. Contracts between vendor and vendee are rationalised.
9. The sales market is enlarged.
10. Better relationships are established between departments.
11. False data and reports are reduced.
12. Discussions are carried out more freely and democratically.
13. Meetings are operated more smoothly.
14. Repairs and installation of equipment and facilities are done more rationally.
15. Human relations are improved.

Hotel Escargo, Unit 3

...RUNNING HEAD: Hotel Escargo Hotel Escargo AIU – MGT656 Abstract In this paper Hotel Escargo’s collected data is graphed and information for the work management and time study analysis is described. One area is area is focused on to create a fishbone diagram to capture the potential root causes. Hotel Escargo Hotel Escargo’s check-in process is expected to be completed in four minutes or less. The average check-in time for guest on July 31st was four minutes and 51 seconds, the minimum time the check-in process took was two minutes and 23 seconds and the maximum time was eight minutes 45 seconds. The issue that occurs during check-in is the average time for check-in is 51 seconds more than is to be expected and exceeds it by four minutes in some cases. Figure 1 will show the data in a table (Hotel, 2014). Work measurement is the application of time and motion study with activity sampling techniques that will determine the time a qualified worker can complete a specific job in a set level of performance. It’s used to determine the budget, planning for manpower, set the schedule, determine the cost, etc (Work, 2014). The work measures to do would be to find three of the least qualified guest service clerks to check-in ten people as efficiently as possible. Once the thirty people are checked-in, the average of their times should determine if there is a problem with the check-in times. A time study analysis looks at a specific job to find the most efficient method to......

...lesser rework and repairs. Looking at the quality metrics: We feel that the First Pass Yield, Defects Per Million Opportunities (DPMO), Shipment On-Time %, Shipping Errors Per Shipment, Warranty Percent of Sales, Warranty Claims per Unit, Survey Complaints (TGW's) per Unit (or per 1000), Customer Satisfaction because as mentioned in the case the customers were more worried about the delivery time initially, then the focus shifts to defects, then to the errors made but the product and finally to breakdown and repair times. There is a strong connection between the between reliability metrics and total productivity maintenance metrics. Quality teams will find many issues that involve maintenance. The technical tools such as Pareto Diagrams, Ishikawa Diagrams and control charts are valuable diagnostics and indicators. Combined with the metrics and tools of Reliability they help the maintenance department permanently solve problems. There are major similarities between CISCO and a company responsible for the design and building of combat vessels the customer is very critical in both, the specifications need to be fulfilled as requested or could lead to huge mistakes or errors. The difference between CISCO and a company responsible for the design and building of combat vessels is the losses due to negligence could lead to capital in CISCO and in the defense company losses will both human and capital.

Each contains and represents the information - feelings, motivation, etc – in terms of whether the information is known or unknown by the person, and whether the information is known or unknown by others in the team. I find it interesting because it is a simple and useful tool for understanding and training self-awareness, personal development, improving communications, interpersonal relationships, group dynamics, team development and intergroup relationships. In productivity interventions, Ishikawa Diagram or Fishbone Diagram is the topic that I found to be noteworthy. Through this diagram, you are able to think about possible causes and reasons leading to an effect or a problem and then find solution for preventing those problems. In the Ishikawa Diagram, you need to sketch it and indicate the needed causes, work the main and side causes out, check the completeness, weight the main and side causes in terms of meaning & influence, check the selected causes for rightness and then the team discusses about the solution. Strategy Maps is the remarkable topic under Strategy Interventions because it describes the logic of the strategy, clearly showing the objectives for the critical internal processes that create value and the intangible assets required to support them.

Kaoru Ishikawa and His Impact on Quality in Business

...Kaoru Ishikawa and His Impact on Quality in Business As with many people who are at the forefront of a cultural movement or paradigm shift, Kaoru Ishikawa’s contribution to Total Quality Management is sometimes over shadowed by other contributors. This comes as no surprise in learning about some of his fundamental beliefs in applied statistical analytics and total quality philosophy. He felt that by applying Quality Control properly, “the irrational behavior of industry and society could be corrected” (Ishikawa, K; 3) By his own admission Dr. Ishikawa became involved in Quality Control by way of data analytics. He began studying statistical methods while at the University of Tokyo; he found the data from his experiments to be widely scattered making it impossible to reach accurate conclusions. At that time the Union of Japanese Scientists and Engineers (JUSE) had the very information he felt would serve and asked to see their materials on statistical methods. In exchange for the use of the materials Ishikawa became one of the instructors and his fascination with statistical methods and QC was born. Genius is often the ability to see around the corners, to see the limitless possibilities with the simplest elements in front of you. Ishikawa’s commitment to Japan’s economic recovery gave him the vision to apply statistical methods and Quality Control in an organized systematic measurable manner. In his personal quest for finding the correct conclusions he was able to help......

...Kaoru Ishikawa: One Step Further Kaoru Ishikawa wanted to change the way people think about work. He urged managers to resist becoming content with merely improving a product's quality, insisting that quality improvement can always go one step further. His notion of company-wide quality control called for continued customer service. This meant that a customer would continue receiving service even after receiving the product. This service would extend across the company itself in all levels of management, and even beyond the company to the everyday lives of those involved. According to Ishikawa, quality improvement is a continuous process, and it can always be taken one step further. With his cause and effect diagram (also called the "Ishikawa" or "fishbone" diagram) this management leader made significant and specific advancements in quality improvement. With the use of this new diagram, the user can see all possible causes of a result, and hopefully find the root of process imperfections. By pinpointing root problems, this diagram provides quality improvement from the "bottom up." Dr. W. Edwards Deming --one of Isikawa's colleagues -- adopted this diagram and used it to teach Total Quality Control in Japan as early as World War II. Both Ishikawa and Deming use this diagram as one the first tools in the quality management process. Ishikawa also showed the importance of the seven quality tools: control chart, run chart, histogram, scatter diagram, Pareto chart, and......

One all the possible causes have been listed you can start to eliminate non-causes of the problem. For example, on my list one possible cause is lost key. However, if we have the key to the car then we can eliminate lost key from our diagram knowing that is no longer a likely cause of reason for the car not starting. When eliminating a possible cause, it is still best to leave it on the diagram by just crossing it out and not removing it. This allows you to return at a later time to determine if you have eliminated true causes of the problem (Dr. McNeese, n.d.). The next step would be to determine how likely each idea is an actual cause of the problem. You can do this by adding notes to each idea such as (v) very likely, (s) somewhat likely, and (n) not likely. For example, if you put gas in the car yesterday and you know the possibility of no gas is not likely,......
