![]() The Ishikawa diagram and many other useful methods feature in our new online training course. Processes are precisely coordinated and optimised any superfluous activities are avoided. Lean management is a holistic principle for streamlining a company’s entire value chain using a number of different methods. Lean management methods for your projects Don’t put off this vital step! There’s always a risk that you’ll lose sight of the true solution to the problem. The final stage involves using the selected primary causes to work out specific courses of action and approaches so you can eliminate the problem once and for all and avoid future recurrences. Which causes are most likely to have a concrete bearing on the problem? Which are more likely to be secondary? This is the stage at which you identify the primary cause – in exceptional cases, you may be able to isolate multiple primary causes. Now you need to arrange the causes you and your colleagues have identified in order of priority. Once you’ve identified the roots, you can tackle them with confidence. As a rule, you’ll need to review each cause several times to identify the problem’s root cause(s). When assigning causes to each main branch or rib, describe them as specifically as possible, breaking them down into sub-branches if necessary. It’s important to focus on your specific problem and adapt the categories on the main branches accordingly. These categories are merely intended as a guideline. Man, Material, Machine, Method, Mission, Management, Measurement, Money Predefined categories provide a useful framework one popular method is the 8 Ms: Then the possible causes are listed along the “ribs” that branch vertically off the backbone. The problem should be defined as clearly and succinctly as possible. The starting point is a horizontal line (“backbone”) pointing to the problem definition on the right (“head”). In visual terms, an Ishikawa diagram resembles the skeleton of a fish, with backbone and ribs. This method is especially suitable for group work and can be implemented as a brainstorming exercise. This involves steadily breaking down the problem’s primary causes until you reach the root cause(s) – hence the term “root-cause analysis”. You’ll use a visual problem-solving process to perform an analytical search for the causes of an existing problem. The method was invented in the 1940s by Japanese researcher Kaoru Ishikawa, and helps to better understand causes and their effects. It’s a graphical representation of all possible causes of a problem and their interdependencies. You’re managing a project when suddenly you come across a problem you have to solve as fast as possible? Let us introduce you to an ingenious lean management method that’ll help you get to where you want to be: the Ishikawa diagram.
