Dr Deming has been teaching total quality management in Japan since World War II. The cause and effect diagram was adopted by Dr W Edwards Deming as a helpful tool for improving quality.

You can use a cause and effect diagram as a working document that is updated as and when you collect more data, or to trial various solutions.

Aim to construct the diagram with the people involved in the problem.

Use data to specify the problem if possible Include as much information as possible in the ‘what’, ‘where’, ‘when’ and ‘how much’ of the problem.

Make sure that your team agree on the problem statement.

This may involve setting up interviews (see getting patient perspectives), carrying out process mapping or surveys which you can use to decide whether the causes identified are correct. Depending on the complexity and importance of the problem, you can now investigate the most likely causes further. By this stage you should have a diagram showing all the possible causes of your delay / problem. Show these as lines coming off each cause line. Where a cause is complex, you might break it down into sub-causes. Continue branching off until every possible cause has been identified. Then, explore each one to identify more specific ’causes of causes’.

Take each of the main categories and brainstorm possible causes of the problem.

An alternative way of creating the branches of a cause and effect diagram is to carry out the Affinity Diagram technique and use the group headings produced there. Make sure that the categories you use are relevant to your particular problem / delay. Categories could include: equipment, environment, procedures, and people. Identify the major factors and draw four or more branches off the large arrow to represent main categories of potential causes. Where appropriate, identify who is involved, what the problem is, and when and where it occurs.

Write it in a box and draw an arrow pointing towards it. Focuses the team on the root cause of the problem – not its symptomsįirstly, identify the problem.Creates a snapshot of the collective knowledge and consensus of a team around a problem.If you know the cause of the delay, you are then better placed to implement the solution.Įnables a team to focus on the content of the problem rather than its history or the differing interests of team members The tool quickly helps you to fully understand an issue and to identify all the possible causes – not just the obvious. The cause and effect diagram is sometimes called a fishbone diagram (because the diagram looks like the skeleton of a fish) or an Ishikawa diagram (after its inventor, Professor Kaoru Ishikawa of Tokyo University). The people involved benefit from shared contributions, leading to a common understanding of the problem. It will help you understand the problem more clearly.īy going through the process of building the diagram with colleagues, everybody gains insights into the problem, alongside possible solutions. The tool can help you identify major causes and indicate the most fruitful areas for further investigation. The ‘effect’ is the problem you are working on, for example ‘waiting time’. It is only by identifying the main causes that you can permanently remove the problem, or reduce the delay.Ī cause and effect diagram is a tool that helps you do this.
