In a Business Process Notation (BPN), a “Resource” connection typically refers to a link between a task or activity in a process and the resource (e.g. person, equipment, material) required to complete the task.
Let’s say we have a process for creating a new product, and one of the tasks in the process is to design the packaging for the product. To complete this task, we need a graphic designer who has experience in packaging design. We can represent this resource requirement using the “Resource” connection in the BPN diagram.
The “Resource” connection links a business object to the specific resources needed to carry out a business process, while the “guide” connection links a business object to instructions or procedures that guide the execution of that process.
