*A resource configuration is a set of physical and human resources configured to provide a business capability.
Creating a resource configuration 
To create a resource configuration from the Infrastructure  navigation menu:
1. Select Infrastructure > Resource Configuration.
The list of resource configurations appears.
2. Click New.

2. Select Structured diagram.
The resource configuration diagram opens.
 
Using a Resource Configuration Diagram 
In a resource configuration diagram, you can insert:
• IT Infrastructures; see Describing an IT infrastructure
*An IT Infrastructure is composed of several connected computer devices (IT network nodes or computing systems) and computer networks.
• IoT Devices,
*An IoT device is both a hardware device and a computing device which provides cvombined hardware and information services to the users using it directly. As a hardware device, it embeds sensors - e.g. accelerometer - which provide data to the embedded computing device. As a computing device, it can host data stores or run applications. Examples: smartwatch with GPS tracker, on-line surveillance video camera with live IP video feed, connected weighting scale with weight history management
• IT networks; see Describing an IT network
*An IT network is set of IT equipment components (e.g.: routers, switches, firewalls) that allow remote communications between computing devices (e.g.: IT server). An IT network can be broken down into sub-networks.
• Hardware elements, see Describing an Hardware,
*Non-IT Hardware can embed computers. Together with their embedded computers, they provide information and IS services. Examples: Connected Truck with Delivery Calendar Application and connected Drone with Online Payment Application. Hardware device can also provide hardware functionalities. Example: Connected fridge providing ordering functionalities and of course a freezing hardware functionality and connected drones fly and provide Online Payment.
• Position types or Org-Units.
*A position type represents a status assigned to an individual or a group of individuals with the aim of defining an organization or a hierarchy.
*An org-unit represents a person or a group of persons that intervenes in the enterprise business processes or information system. An org-unit can be internal or external to the enterprise. An internal org-unit is an organizational element of enterprise structure such as a management, department, or job function. It is defined at a level depending on the degree of detail to be provided on the organization (see org-unit type). Example: financial management, sales management, marketing department, account manager. An external org-unit is an external entity that exchanges flows with the enterprise. Example: customer, supplier, government office.
*For more details on creating a human asset, see Adding an Org-Unit or a Position Type.
 
• Ports and network channels, see Describing technical communications.
• service and request points, see Describing the services communications.
• Service Interaction, see Describing technical communications.
*A Service Interaction represents an interaction for service purpose between entities in a specific context inside or outside a company. These entities can be enterprise org-units, applications, activities or processes, as well as external org-units. The content of this interaction is described in a service interface.
