Working on Parts of the Model Remotely
In some cases, it is necessary for a separate team or developer to work on parts of the model remote from access to the central database.
To do this you will need to create a model sandbox and then export the relevant Packages from the sandbox using the Component Sharing Wizard. This is imported into a new model by the subcontractor, modified as necessary and exported to return it. The original author may difference the Component Sharing Wizard file before import to review the changes and then import it into the sandbox. The sandbox can then be rebased and reconciled.

Note that this process ensures that it is possible for both the original author and subcontractor to make changes to the Package then reconcile them in a managed way. However, working in parallel in this way should be done carefully as the problems with reference to the isolation-versus-integration conundrum.
