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.
Asking why the first time could result in the answer that this product is sold at a higher price point than the other similar products in the line.
That higher price point could obviously be a deterrent to sales, so the natural follow up question would be why is this product being sold at a higher price?
In this case, we only went through three levels of ‘whys’, and we were able to get down to the heart of the matter.
It won’t always be that easy, but following the whys is usually going to lead to a solution at one point or another.
It stimulates the identification of deeper potential causes. You and its taking ‘X’ time to work around and its taking ‘X’ amount of resource and this is why…” At this point, the Business Analyst should be thinking, you haven’t actually told me why you’re having this huge problem! So our job is to finish this sentence from “and this is why…” That’s where these techniques come in and why they are possibly the most important tools in the toolbox. And thereby find the right solution for the right causes to the right problem. You can print it off and read it before a meeting to give you a bit of ‘Dutch courage’. I soon determined that the root cause was due to the information, which was available in the system.
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.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.I PROMISE you will get to the bottom of a problem a lot quicker than if you don't use them. One Problem, One Head Draw a FISH head Like this: Write down the issue or problem statement in the FISH head. Decide if some of them need more investigation or whether you feel like you’ve found your root cause. Meet with important or relevant people to discuss your findings. When someone comes to you with a problem (or effect) First ask about the problem using 5 Why’s.And I’ll show you exactly how I completed the cause and effect diagram right now. Or even if you don’t feel like you’ve fully completed your questioning. Which will form the basis of your visual Cause and Effect relationship analysis. Then develop a Fishbone diagram to list ALL the possible reasons (or causes) Then do some analysis Finally use the 5 why’s again to literally HIT the ACTUAL root cause.For example, some issues will only need to have the ‘why’ question asked two or three times before reaching a satisfactory solution, while other problems will require that you go six, seven, or even eight layers deep.This technique is often used in conjunction with the Drill Down Technique as part of a Root Cause Analysis.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.5Y is a problem solving technique widely adopted in root cause analysis (RCA) as a part of the Problem Management module in ITIL.5Y is rather 5 Why's and involves framing questions beginning with Why to arrive at a root cause from the actual problem statement.There are other problem solving techniques apart from 5Y that can be used for similar purpose like the Fishbone diagram, Cause-effect analysis etc.5 Why's is the most common of these methods as it has a step by step approach to arrive at the actual root cause , which in turn aids the RCA process.
