Mio wants to understand why people do not use the full potential of computers. To put it into the fishbone diagram, draw a line branching off from methods, and write the answer at the end of the line. A lot of time is wasted double or even triple checking data because it’s unreliable.Īs a result, her answer to the first “why” is: Employees used manual calculations, leading to inaccurate data, requiring time to find problems and correct them. To figure out why Alencia has so many problems, Mio has decided to first focus on the Methods the company has employed.įrom here, the 5-why analysis is applied as usual, and Mio asks herself “In terms of methods, why was application processing behind schedule?”įrom her observations, Mio understands that a lot of the statistics used in the company are wrong because many employees are still collecting data and calculating figures using paper and a calculator, before inputting that data into a spreadsheet. Equipment, Process, People, Materials, Environment, and Management.
4S’s – Surroundings, Suppliers, Systems, Skills (recommended for service industry). 8P’s – Price, Promotion, People, Processes, Place / Plant, Policies, Procedures & Product (or Service) (recommended for administration and service industry). 6M’s – Machine, Method, Materials, Measurement, Man and Mother Nature (Environment). 4P’s – Policies, Procedures, People and Plant. 3M’s and P – Methods, Materials, Machinery, and People. There are also a whole set of common cause categories, some of which are listed below: She has drawn additional lines from the spine and placed boxes containing each individual category. Mio has chosen to focus on methods, management, process and people, since the problem here is related to these four main areas. You can choose to focus your line of inquiry by choosing a set of cause categories: main topics which you will base your 5-why analysis on. In this case, it is “Application processing was behind schedule.” The line represents the spine of the fish. I have found that using a computer to create fishbone diagrams actually interrupts the flow of ideas, as it requires fiddling around with text boxes and other unnecessary formatting.įirstly, on a sheet of paper, draw a long line with the box at the end. I strongly recommend using paper and pen when you perform the analysis, as it allows you to put your ideas down much quicker than a computer would. In this article, we will be using the same scenario as the table analysis example in the previous article. The table method is like the shotgun approach, in which we think of as many possible causes as possible without a specific path. In other words, this diagram is similar to a surgical strike, which provides more precision. The strength of the fish bone diagram is that it allows you to focus on specific cause categories, which may help you to better focus your line of enquiry. The fishbone diagram, also known as the Ishikawa diagram, is another tool to provide you with a visual representation of your 5-why analysis. More information: An Introduction to 5-why, 5-why Analysis using a Fishbone Diagram and The Weaknesses of 5-Why The fishbone (or Ishikawa) diagram is another way to visualize your 5-why analysis, and allows you to classify your analysis into broad categories.
