Cause and Effect Diagrams and SPC for Excel
Our software, SPC for Excel, makes it easy to construct a cause and effect diagram using Excel. A blank cause and effect diagram is inserted into your workbook when you select the fishbone icon from the SPC for Excel ribbon. The diagram has the major cause categories: machines, measurement, methods, materials, people and environment. These can be changed. There is an "Add Item" button that allows you to add a new item to the diagram and then simply drag the item under the major cause where it belongs. There is also an "Add Sub-Item" button that allows you put causes at a diagonal under the items.
