Collaborative project management helps implement project management that extends across the borders of individual corporate enterprises. The tools and processes that can be used to achieve this objective, the reason why collaborative project management is necessary, and the benefits to be gained from the CPM Recommendation are described in detail in Part 1 of this Recommendation (Reference Model; PSI 1-1).

The CPM Usage Guide provides information on using the tools presented in Part 1.

Part 2 of the CPM Recommendation (Data Exchange Model; PSI 1-2) defines the data objects that can be used to exchange project management information relating to CPM between different PM systems. This includes the tools defined in PSI 1-1 in particular. The associated transmission mechanisms are also described.

In addition to this second part of the Recommendation, note should also be made of the Implementation Guide, which contains recommendations and explanations regarding implementation of the described data model within the context of CPM. All documents are available at www.prostep.org.
