A diagram that depicts project activities and their interrelationships is called a:
Quality Glossary Definition: Interrelationship diagram Show
Also called: interrelationship diagraph, relations diagram or digraph, network diagram Variation: matrix diagram An interrelationship diagram is defined as a new management planning tool that depicts the relationship among factors in a complex situation. The interrelationship diagram shows cause-and-effect relationships. Its main purpose is to help identify relationships that are not easily recognizable. An interrelationship diagram borders on being a tool for root cause identification, but it is mainly used to identify logical relationships in a complex and confusing problem situation. In such cases, the strength of an interrelationship diagram is its ability to visualize such relationships. The process of creating an interrelationship diagram can help groups analyze the natural links between different aspects of a complex situation. When to Use an Interrelationship Diagram
Interrelationship Diagram Basic ProcedureMaterials needed: Sticky notes or cards, large paper surface (newsprint or two flipchart pages taped together), marking pens, and tape.
Remember, the number of arrows is only an indicator, not an absolute rule. Be sure to check whether ideas with fewer arrows also are key ideas. Draw bold lines around the key ideas. Create an Interrelationship Diagram for Root Cause Analysis
Tools for Creating an Interrelationship Diagram
Interrelationship Diagram Example #1A computer support group is planning a major project: replacing the mainframe computer. The group drew an interrelationship diagram (see Figure 1) to sort out a confusing set of elements involved in this project. Figure 1: Interrelationship Diagram "Computer replacement project" is the card identifying the issue. The ideas that were brainstormed were a mixture of action steps, problems, desired results, and less-desirable effects to be handled. All these ideas went onto the diagram together. As the questions were asked about relationships and causes, the mixture of ideas began to sort itself out. After all the arrows were drawn, key issues became clear. They are outlined with bold lines.
Interrelationship Diagram Example #2A small hospital was concerned about the productivity of its doctors because they were the most expensive employees and critical for the treatment of the patients. Having taken numerous steps toward ensuring high productivity, hospital management was baffled when productivity steadily declined month after month. Since this development was unexplainable, management sought to gain insight into causes and effects among the different factors at play. They decided to create an interrelationship diagram and include the following factors in the analysis:
When the interrelationship diagram had been completed (Figure 2), attention shifted from improving the doctors’ work situation to ensuring the availability of nurses, other support functions, and operational equipment.

What is another name for activity on node diagramming?There are two main types of network diagrams in project management: the arrow diagramming method (ADM), also known as “activity network diagram” or “activity on arrow”; and the precedence diagramming method (PDM), also known as “node network” or “activity on node.”
Which of the following is an activity that occurs during project initiation and planning?Within the initiation phase, the business problem or opportunity is identified, a solution is defined, a project is formed, and a project team is appointed to build and deliver the solution to the customer.
What is the name of a technique used to display schematically the logical relationships among project activities and their sequencing?A project network diagram is a schematic display of the project's activities and the logical relationships (dependencies) among them.
Which type of tool helps project managers identify bottlenecks in project development?ProWorkflow can help you identify bottlenecks
ProWorkflow is a sophisticated project management tool that gives project managers full visibility into workflows and allows them to manage remote teams and complex tasks.
