As mentioned earlier, Commitment can be associated with a concrete deliverable. <br/>Commitment inherits from Agreement which inherits from BusinessInteraction. Therefore, Commitment inherits the association to BusinessInteractionItem which is related to ProductSpecification, ServiceSpecification, and ResourceSpecification.  <br/>So if the supplier/partner is obligated to provide a product, service or resource, the Commitment is associated to the corresponding specification.<br/>If any other kind of project deliverable is the Commitment of a supplier/partner this can be modeled CommitmentTermOrCondition, which inherits from AgreementTermOrCondition. CommitmentTermOrCondition is associated to ProjectDeliverable, defined in the Project ABE.<br/>
