![]() ![]() Failure mode and effects analysis (FMEAs) for small business owners and non-engineers: determining and preventing what can go wrong. Step seven: you may use one of the other problem-solving techniques (5whys, appreciation, and drill down) to analyze each element for more details if needed.

How easy would it be to fix or control?.How likely is this cause to be the major source of the issue or variation?.Step five: Analyze your diagram by asking the following questions: Then Draw your lines off the sub causes you determined in the previous step. Step four: Break down each sub-cause into its elements. Step three: Brainstorm each cause and find the sub causes: Step two: Determining the possible casual factors by including all categories, which can be the causes of the problem. Then collected data about the whole delivery process and all tasks that needed to be done to make the delivery on the expected time and decided to analyze it by a “fishbone” diagram according to the complexity of the problem. The problem-solving team identified the problem by observing the frequent complaints about late delivery. Įxample: Using this method will illustrate the complexity of a “late delivery” problem. ![]() Work on the Causes that have a result of VV, VS, and SV. Put the answers to the two questions together.

Analyze your diagram by asking the following questions:.Break down each sub cause into its elements.Brainstorm every cause to identify the sub causes, and then draw branches off every category to write down the sub causes you identified.Each category is a potential cause where you can find the defect in. Identify the relevant category according to the type of business (you may refer to the typical categories in step two or manage your categories according to your process).Write down the problem (the effect) on the side of a paper or board.The 4 Ss’ (used in service industries)Īn alternative used for service industries uses four categories of possible causes : ![]() The 8 Ps are primarily used in product marketing.
