To better explain this concept and how it can work in practical application, let’s walk through a basic example that could be relevant to a number of businesses.
It helps you Drill down further when used together with 5 Why’s. 5 Why’s can be used any time by anyone, it’s simply how you structure your questions and we ALL ask questions at some point. To date, I’ve used the 5 why’s technique in at least 90% of the projects I’ve worked on. Because you can only get a full understanding of anything by asking why. The Japanese firm Toyota invented the technique and there are now hundreds of web pages describing the background to these techniques in great detail. When I was working on a project that was to improve a procurement management system. Yes - Give me better questioning techniques for FREE But anyway: As you can see as I dug further into the details, it became clearer and clearer where I needed to focus my investigation. Was not available on-screen at the right time of processing. A quick email to the IT department for them to configure the users screens and show the already-available info on the right screen at the right time – SIMPLES! A reduction of processing time of approximately 70% for over 95% of credit notes.Fishbone can be used when a more detailed analysis is required for a specific problem. This simple change saved £000’s of pounds by not having to go to a 3 party supplier to have new system functionality developed for processing documents efficiently. If you’re brainstorming with others they’ll quickly know what it’s about. Major Factors List 5 of the major factors involved Here are the traditional ‘fishbone’ major factors: But you don’t necessarily have to stick to these. Get your thinking cap on and brainstorm around each heading to place ideas or issues around the relevant header Drill down into the issues (maybe using 5 why’s ) Group them into relevant subcategories Keep going until you have a diagram showing all the possible causes. And you will have something that looks a little bit like this: Step 5.Here’s the bottom line: If you use the 5 Why’s technique in conjunction with the Cause and Effect (or Fishbone) Diagram. You could come up with your own depending on earlier research. Boning Out Make the bones of your fish and add these as headings for each bone. Analyse the Fish’s bone(s) Look for causes that appear more than once.When that is the case, you will start to notice that this same problem comes up over and over again – likely costing you time and money in each instance.Rather than dealing with the same problems over and over again, and making your business less efficient in the process, you should consider using the ‘5 Why Analysis’ technique in order to get down to the heart of the issue at hand.After consulting with another department in the business, you find that the product is made from more-expensive raw materials, resulting in the need for a higher price at market. The next question asks why the product is made using more expensive materials, at which time it is discovered that the purchasing contract for those materials is old and should have been renegotiated.So, with that information uncovered, the business can work on a new deal for the materials, lower the cost of the unit, lower the price of the unit at market, and likely sell more in the end.This product is similar to other products which are selling nicely, but it is underperforming and is costing the company money at this point.So, at first blush, the immediate reaction might be to simply take the product off the market and cut losses.Unlike many other business methodologies, the five whys is a very loose methodology that relies on the experience and knowledge of the people involved in order to reach a satisfactory conclusion.Basically, using the 5 Why Analysis simply demands that you continue to ask ‘why?
