In Qarma, there are two models of managing production units (production units in Qarma means factories or production sites). 

  1. Delegated model. Each supplier has its own list of production units. If two suppliers use the same production unit, it will be present twice.
  2. Managed model. There is a total list of production units, and each supplier reference the ones they use. 

Understanding the two models

The principle of model 1 is displayed below:

Three suppliers all use production unit B, and that it is present three times in the Qarma data. 

The principle of model 2 is displayed below: 

Production unit B is only present one time in the data, and all suppliers reference this production unit.

Delegated modelManaged model
Main benefitSuppliers can manage all data themselves and add new production units and manage their information on their ownAudits, CAP and other data is only present one time in the data. This makes it easier to manage 
Data integrationsNo requirementsData sent to Qarma needs to have production unit numbers or names that are unique across suppliers
Implications for audits and CAPAlways linked to suppliersCan be linked to suppliers
TieringNot possibleProduction units can be linked as upstream or downstrean
