Interrelationship diagrams identify influencing factors by counting the number of outgoing and incoming arrows for each factor. The factor with the most incoming arrows is called the root cause, while those with more outgoing arrows are drivers.

Introduction to Interrelationship Diagrams and Digraphs

An interrelationship diagram is a tool for analysing complex situations and helping a team understand the natural links between different elements of a problem. It can be used in place of an affinity or fishbone diagram, and in conjunction with other tools such as process mapping and root cause analysis.

Rather than using boxes to represent ideas or factors and lines connecting them, an interrelationship diagram uses circles with a line between each one to show the relationship between them. This enables teams to think of connections in many directions, which helps them break down complexity and encourages lateral thinking as well as the use of linear reasoning.

The first step in making an interrelationship diagram is to select the subject that the team wishes to analyse. This can be a problem, inefficiency or opportunity. Once the subject is selected, the team should brainstorm all of the possible influences on it. This should be done on a sheet of paper, with the subject written at the top. Depending on the size of the organisation and the number of potential problems, it may be necessary to make more than one sheet.

When the ideas have been grouped, it is important to ask for input from all of the members in the team, as it is possible that some of the relationships will not be immediately apparent. The next step is to look at each group of ideas and decide which have the most incoming or outgoing arrows to and from them, and identify those as critical influencers.

Once the key issues have been identified, the group can then analyze the root causes of these and decide upon a course of action for the problem.

Creating an Interrelationship Diagram: A Step-by-Step Guide

An interrelationship diagram is a tool that identifies the natural links among different aspects of a complex situation. It can be used as a standalone method of problem-solving or in conjunction with other tools such as fishbone and affinity diagrams to explore ideas in more detail.

To begin creating an interrelationship diagram, start by selecting a topic to examine. Ideally, this should be a current problem in need of a solution and it is best to use the tool with a group to encourage brainstorming.

Brainstorm a list of items that pertain to the selected topic, writing each item on a separate 3” x 5” card. A decision can be made to place closely related cards together or shuffle the cards and display them randomly for further exploration. In the latter case, this will help to avoid bias and discover new ways of looking at a problem.

Once the list is complete, add arrows from each of the items to the ones that they influence or cause. For strong relationships, use a solid line and for weaker connections, a dashed line. Then, count the number of arrows going into and away from each item to recognize the root causes or drivers.

Those with the most outgoing arrows are the main factors that need to be addressed and those with the most incoming arrows are key effects that will need to be resolved in order to solve the main issue. This step can take some time but it is important to analyze the information thoroughly so that you can find a permanent solution for the problem. Using an online drawing tool such as Edraw will speed up this process by allowing you to easily edit and format your design with text boxes, arrows and connectors in multiple shapes.

Analyzing and Interpreting Interrelationship Digraphs

The process of creating an interrelationship diagram allows teams to explore the natural links between different aspects of a problem. It encourages team members to avoid thinking in a linear manner and allows them to find key problems and their root causes that may be otherwise hidden in the problem at hand.

Like the Fishbone or Affinity diagram, an Interrelationship Digraph is a 7M tool that takes multiple inputs into account and helps to identify the logical (and often causal) relationships amongst them. It is a tool that is particularly helpful when working with complex issues, as it helps to break down the complexity of the issue at hand.

It is also a useful tool to utilize during brainstorming sessions, because it can help teams to identify the connections that are not immediately apparent. It allows groups to brainstorm and consider more ideas than the standard line of thought associated with a Fishbone or Affinity diagram, thus increasing the likelihood that they will uncover critical x-factors (variables that cause something else to occur).

The final step in using this tool is to review all of the connections that have been made and to determine which are the most important. This can be done by counting the number of arrows drawn from each element to the others (with arrows pointing away from an item indicating that it influences another).

This step helps to identify which elements are the most fundamental or “core” to the problem at hand, and it can assist teams in narrowing down their focus for further investigation or problem solving. It also gives them a sense of which issues are the most urgent or should be tackled first, as these tend to be the most direct and likely to yield results.

Practical Applications of Interrelationship Diagrams in Business

As one of the 7 New QC Tools, interrelationship diagrams are used to identify logical relationships in a confusing problem situation. When used correctly, the process forces a group to think in multiple directions instead of only looking at things in a linear way. This allows for the natural emergence of key factors and drivers.

A graphical tool, the interrelationship diagram is used to depict different types of connections in a complex problem situation. It is a great way to identify the root cause of problems and find permanent solutions. The diagram is made up of a series of circles, each representing a separate element that influences the problem. Connecting lines are drawn between each circle to represent the logical relationship between them.

The first step in drafting an interrelationship diagram is to write the central problem at the top of the page. Then, start brainstorming and write down all the possible elements that influence it. It is important that all of the influences are included so that a complete picture can be obtained. The next step is to draw the arrows connecting each element to the central problem. The direction of the arrows indicates whether an element is a driver or an indicator. Those arrows that have many tails are considered to be indicators while those that concentrate a lot of incoming and outgoing arrows are considered to be the driving factors.

Once all the arrows are drawn, count how many of them are pointing into the central problem and how many are pointing away from it. Then, analyze the results to see how each of the elements interacts with the other. The key is to determine the causes of each element and how they can be controlled or eliminated to solve the central problem.

Advancing Problem-Solving with Interrelationship Analysis

Interrelationship diagrams encourage participants to view processes outside of a linear framework. Unlike the Fishbone Diagram, which singles out a main input to a problem, an interrelationship digraph helps users see relations and influences between multiple inputs and outcomes. It also helps users see the importance of multiple causes. This new management planning tool allows teams to analyze the natural links between different aspects of a complex situation and can identify root cause analysis that is not easily recognizable.

Like affinity mapping, it’s important to note that the interrelationship chart does have its limitations. This method of analysis may not be as effective for highly complex situations and multi-faceted projects because it requires careful organization and grouping of ideas into clusters of similar concepts. It also relies on diverse perspectives within a team to avoid bias and skewed decision-making.

Initially, a team brainstorms ideas and places each on a card or piece of paper. Afterward, they can choose to place closely related items together right away or to shuffle the cards and display them in a random order on the table. For each idea, the team then analyzes the cards and draws relationship arrows from one to another. The cards that concentrate a lot of outgoing arrows represent the root cause and those with a lot of incoming arrows are the final effects.

The process of drawing an interrelationship diagram can be time-consuming if done alone. As such, it’s best used in a workshop setting where team members can work together to brainstorm and build on each other’s ideas. Once the diagram is complete, it can be analyzed to find root causes and possible solutions for problems.
