Q3: Why don’t we have enough people?Īnd so on at least five times altogether. Q2: Why are we short-staffed?Ī: Sales have increased, and we don’t have enough people in billing to keep up. For example, if a possible cause of slow invoicing is that you’re short-staffed, the process could look like this: Q1: Why is invoicing slow?Ī: We’re short-staffed. The facilitator can encourage further discussion by using the “five whys” method-asking “why” at least five times to find the root cause of a problem. Some bones may end up with more possible causes than other bones.

The facilitator should clarify any stick notes that are unclear and make sure they’re put on the right bone. 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.

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.You get input from each function that may be responsible for causing the problem.Employee involvement helps build consensus around the nature of problem being addressed, underlying causes and solutions.1) Involve your teamĮngage your team in the exercise from the beginning. Gogolin breaks down the problem-solving process using the fishbone diagram into five steps.
