An Integration Project is a package containing model elements defining the configuration of a module from an ARINC 653 of view. It does not contain the implementation detail of processes - it only goes so far as to reference the processes using process parts. The implementation detail of processes occurs within Application Projects.
Create an Integration Project from a Package: Right-click the owning Package, point to ARINC 653, point to New, and then click Integration Project. The profile prompts you for an integration project and module name and then creates the Integration Project and the default diagrams and items for the configuration.
