The aim was to provide a method with which the causes of a specific problem could be analyzed in a structured manner. It is presented in the form of a fishbone diagram: the problem (the effect) is on the right, from where the main cause categories branch out as lines - the so-called \"fishbones\" - to the left. Initially there were four categories, but these were gradually expanded to six and then eight as the business world became more complex and more factors needed to be considered. Each of these main categories is further subdivided to capture possible individual causes. The result is a clear, graphical representation of complex relationships that encourages both analytical thinking and creative solutions.     <\/p><\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t<\/div><div class=\"et_d4_element et_pb_row et_pb_row_5  et_pb_css_mix_blend_mode et_block_row\">\n\t\t\t\t<div class=\"et_d4_element et_pb_column_4_4 et_pb_column et_pb_column_5  et_pb_css_mix_blend_mode et-last-child et_block_column\">\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t<div class=\"et_pb_module et_d4_element et_pb_text et_pb_text_3  et_pb_text_align_left et_pb_bg_layout_light\">\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t<div class=\"et_pb_text_inner\"><h2><span class=\"ez-toc-section\" id=\"Structure_and_elements_of_the_Ishikawa_diagram\"><\/span>Structure and elements of the Ishikawa diagram<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>On the right is the effect, i.e. the problem to be analyzed. From there, there are usually six main branches, which typically represent the following categories: <\/p>\n<ol>\n<li><strong>Human (personnel):<\/strong> This category includes errors caused by human behavior, inadequate knowledge, communication, conflict or motivation<\/li>\n<li><strong>Machine (technology):<\/strong> Technical defects, outdated systems or lack of maintenance, for example, fall into this area.<\/li>\n<li><strong>Material:<\/strong> This refers to the quality of the materials used, availability or specifications of the raw and auxiliary materials.<\/li>\n<li><strong>Method (processes):<\/strong> Workflows, standards, procedures or, for example, the project management method fall into this area.<\/li>\n<li><strong>Milieu (environment):<\/strong> All environmental conditions, the physical or organizational environment that occur outside the company but still have an influence on the process, fall into this category. These can be, for example, environmental influences such as temperature or humidity, but also competitors, legal requirements and industry developments. <\/li>\n<li><strong>Management:<\/strong> Managers also often have a significant influence on problems. Management errors, inadequate planning or poor communication by managers therefore fall into this category <\/li>\n<li><strong>Measurement (data):<\/strong> This involves, for example, incorrect or missing measurement data or incorrect interpretations.<\/li>\n<li><strong>Money:<\/strong> Cost pressure, budget cuts or wrong investment decisions often also have a major impact and should therefore be considered.<br \/>These categories serve as a framework for structured brainstorming.

Now draw a template for the diagram and note the problem on the right-hand side as the head of the fish.  <\/p>\n<p><strong>2. collect causes (brainstorming):<\/strong><br \/>The team then collects possible causes for each main category and notes them down on the corresponding branches. Creativity is required here, but also factual knowledge. The aim is not yet to collect only high-quality causes, but to look at the problem from different angles in order to identify less visible causes.  <\/p>\n<p><strong>3. analyze causes:<\/strong><br \/>Each cause is then scrutinized: How plausible is it? Is there evidence or circumstantial evidence? The causes are evaluated according to their relevance, frequency or influence on the problem, e.g. using an <a href=\"https:\/\/parm.com\/en\/abc-analysis-in-project-portfolio-management\/\" target=\"_blank\" rel=\"noopener\" title=\"ABC Analysis in Project Portfolio Management\">ABC analysis<\/a>. In this way, select the most likely causes or the causes with the greatest impact.   <\/p>\n<p><strong>4. derive measures:<\/strong><br \/>Such a root cause analysis only makes sense if measures are subsequently derived from the result.
