The structure of a negotiating offer presented in the figure below is basically the same as a draft agreement. However, a bargaining offer contains additional elements of the trading environment and trading restrictions. The negotiating model of the WS agreement consists of three levels, with a clear separation between these levels: the level of negotiation, the level of agreement and the level of service. These levels are shown in the figure below. The context of the negotiations defines the role of the participants in the negotiations, their commitments and the nature of the negotiation process, such as. B the negotiation of new agreements or the renegotiation of implementation agreements. As an option, domain-specific trading parameters, such as the number of rounds of negotiations or the deadline, can be indicated. The status of the trading offer is used to describe a particular state in the lifecycle of a trading offer. The status of the bargaining offer may contain domain-specific data that can be used by the negotiating parties to exchange information on the supply lifecycle and effectively advance the negotiation process.
The following figure shows the terms that negotiated offers can have and valid status transitions. Negotiation restrictions are a method of controlling a negotiation process. A participant in the negotiations uses trading restrictions to define the structure or certain values applicable to counter-offers based on a given offer. Therefore, restrictions on negotiations are a means of expressing the demands of a party to the negotiations. The negotiating restrictions are structurally identical to those set out in an agreement document. The level of negotiation provides a protocol and language for negotiating contractual offers and counter-offers and establishing agreements on the basis of negotiated offers. The negotiation process includes the exchange of bargaining offers and counter-offers. Bargaining offers as defined in this specification are by nature non-binding.
They do not contain a commitment of the Responders agreement to create an agreement on the basis of a negotiated offer. They merely signal the willingness of both parties to reach an agreement afterwards. However, it is possible to define languages that can be used in conjunction with this specification to carry out binding negotiation processes. This also applies to renegotiated agreements, but additional information is needed when a renegotiated agreement is established. This information is stored in a renegotiation extension document and transmitted to the createAgreement (createPendingAgrement) method of an Agreement Factory (PendingAgrey) as a critical extension. The „extension of renegotiation“ document contains the final reference to the original agreement, which was renegotiated, and possibly domain-specific extensions. If a renegotiated agreement is successfully established, the status of the original agreement must change to Complete. The negotiating offer is a non-binding proposal for a possible agreement that will move one party to the negotiations over another. One or more offers to negotiate one or more parties to the negotiation may be preceded by a binding contractual offer within the meaning of the WS agreement.
The offer describes the service for which an ALS must be negotiated and the corresponding quality of service in terms of guarantees.
