De openbare consultatie loopt tot 22 oktober. OpenProposal moet voorstellen en de route naar aankoopafspraken structureren voor agents.

Onderscheid een informatieverzoek van een onderhandelbaar voorstel en een bindende afspraak. Leg bevoegde koper, verkoper, valuta, totaalplafond en het moment van menselijke goedkeuring vast. Een overtuigende uitleg van een agent vervangt deze gegevens niet.<\/p><\/section>\n<section><h2 id=\"trend-nl-2\">Oefen op papier v\u00f3\u00f3r een transactie<\/h2><p>Gebruik een fictieve campagne en twee fictieve leveranciersvoorstellen. Kan een collega de commerci\u00eble beslissing uitsluitend uit het dossier reconstrueren? Neem een dubbel verzoek, gewijzigde prijs en niet-beschikbare plaatsing op. Bepaal hoe de workflow een herhaalde opdracht herkent zonder een tweede verplichting aan te gaan. Houd de oefening los van live inkoopaccounts. Het doel is ontbrekende controles vinden, niet bewezen interoperabiliteit nabootsen.<\/p><\/section>\n<section><h2 id=\"trend-nl-3\">Wat marketeers nu aan leveranciers kunnen vragen<\/h2><p>Vraag welke specificatieversie wordt ondersteund, welke acties live zijn, hoe rechten worden afgedwongen en wat er gebeurt na een mislukt of herhaald verzoek.
