![]() ![]() How this lines up with the Scientific methodĪs discussed in a past post, the scientific method is one of the oldest documented problem solving techniques we have at our disposal, so it is not surprising that later problem solving techniques can have a very similar format. Once the fishbone is completed with supporting data, it’s time to investigate from the most likely potential causes to understand how they may be impacting the problem. Within each categories there are secondary or root causes that can be investigated for their influence on the problem. In most manufacturing settings these problems are pretty easy to establish simply because these same 6 categories impact everything in manufacturing in one form or another: The reason that these categories are being established is to see how various factor may actually influence the problem. The nature of these categories have to be discreet and avoid overlapping as much as possible. Once the problem is defined, very specific categories of the problem are established. This method of problem solving is very methodical and visual, but before you approach it, you have to have a very well defined problem, with defining the problem, all efforts will be in vain. One method of problem solving known as an Ishikawa diagram (AKA cause and effect diagram, AKA fishbone diagram), was developed in the 1960s by Dr. See if a shift in one of these causes can give you a different effect to explore.” - Dr. “Think of at least four factors which influence your problem. In other words, answering these questions is the first stage of solving a problem also known as “Defining the problem”. Exactly what part of the tire is leaking?Īs a matter of fact, unless you take time to answer some of these basic questions, you may only change this tire to simply have to keep changing it over and over again.Inspecting the tire or otherwise getting more information can help point you into the direction for the specific cause of the flat tire. In other words, if you have a flat tire, there are on a few possibilities for what caused it: ![]() In that way, life in the natural world is like a mathematical function. Meaning that, for a specific effect, you can usually trace it back to a specific set of causes. Most problems, particularly problems faced by engineers, could be described as ‘deterministic’. ![]()
