A set of organizational patterns may have been used during the two previous phases especially for the OID (Organization Identification) and IRI (Interactions and Roles Identification) activities and for the Holon Government identification task. This activity aims at integrating the code of these patterns inside the currently designed application. It also intends to provide a framework for reusing code of previous applications that can be reused in the current one. Integrating pattern source code may require some adaptation work; for instance it is often necessary to adapt the management of input values provided by the remaining part of the application to the reused code.
