Creating a Process Relationship Diagram


The purpose of a process relationship diagram is to show the interrelationship of all processes in a given functional domain (such as Marketing, Sales, or Service). In order to create a process relationship diagram, you must first develop and validate the business process diagrams that comprise the functional domain you will represent in the process relationship diagram. Creating process relationship diagrams is the most challenging form of business process mapping, as it requires an in-depth understanding of the subject matter you are documenting and a clear grasp of the sequence and inter-relationship of the processes you are connecting.

Process relationship diagrams are a navigational aid for a logical collection of business processes. Project planning teams or business process redesign teams generally rely on one designated individual to develop the skills necessary to create process relationship diagrams for their goals, and this individual can facilitate discussions to gain group-wide consensus on the structure of these diagrams.

To create a process relationship diagram

  1. Create a swimlane template for the diagram. Three suggested swimlane names are the following:
  2. Create boxes on a page to depict the main process domains (logical collections of business processes) that are included in the functional domain that you are mapping. You should order these in the sequence in which they occur, as shown in Figure 20.

  4. Inside each process domain, create boxes to define subprocess domains if there are logical groups of business processes that occur before another set of business processes. You can offset these separate subprocess domains inside each process domain by using a different color for the subprocess domain boxes.
  5. Insert boxes for the business processes, connecting them in the logical order in which they occur, as shown in Figure 21.
