If invoicing is slow, causes in the manpower (people) bucket could include insufficient personnel, inadequate training and poor support from other departments.Īdd a sticky note on the manpower bone for each cause, then work your way through the rest of the major factors. Going one major factor at a time, each participant uses a real or virtual sticky note to write down possible causes of the problem in that function. Example of a 5M fishbone (Ishikawa) diagram Label each bone of the fish with a major factor. 4 S’s: surroundings, suppliers, systems and skills.7 P’s: properties, people, place, product, physical evidence, promotion and price.8 M’s: same as 5 M’s plus mission (purpose), management (leadership) and maintenance.5 M’s: manpower (people), machines, material, method and measurement (process).With your team, pick a set of categories that are the most relevant for your problem or company. There’s no set list or number of major factors, though some common definitions do exist. These are called the “major factors.” Each bone represents a function or department of the business. Now it’s time to define the “bones” of the fish. we’re running out of room in our facility.Problems most commonly have to do with one of three areas: This should be no more than a short sentence and is typically written on a sticky note that is put at the head of the fish. Next, the team should get consensus on the issue to be discussed and articulate it in a clear, concise problem statement. The exercise can also be effective in a virtual environment. Teams can meet in person and work with a fishbone diagram put up on a wall, using sticky notes. While a facilitator with experience in operational efficiency can lead the process, this exercise can also be done whenever a problem surfaces. This should include members of the leadership team and people from other functional areas of the business. Gogolin says five to 10 people are typically involved in a fishbone exercise. One of the three key tenets of lean is to involve the people closest to a problem who deal with it every day. It’s consistent with the lean methodology.
