The following Figure is a simple model of how a Product is modeled.<br/>A ProductOffering represents what is externally presented to the market for the market’s use and can be simple or bundled (atomic / composite pattern).<br/>A ProductOffering represents how the ProductSpecification is sold (i.e. packaging rules, prices, alterations, commitments…).<br/>The ProductSpecification represents a product specification as perceived by the business user and specifies what the marketing operator wants to sell at a functional level (i.e. what are the capacities, which usages are available…).<br/>It can represent:<br/>        • material goods (Terminal, phone, mobile, fax, modem)<br/>        • or intangible goods (like an Anti-Spam service for email).<br/>A ProductOffering makes available at least one ProductSpecition directly or indirectly (through contained ProductOfferings).<br/>Vice versa, a ProductSpecification may be made available as one or more simple ProductOfferings.<br/>A Product represents exclusively the instantiation of a ProductOffering or ProductSpecification by a Party playing a PartyRole, such as a Customer. <br/>
