Products modelling is arguably the mother of all case studies as it may encompass symbolic and actual artifacts together with any possible life-cycle.
Hence the importance of identifying a representation backbone that can be fleshed out depending on core business concerns like design production, marketing, sales, etc.
Core Product Representation
Basic product description can be organized along its life-cycle, namely specifications (What is to be done), development (How it’s to be done) and delivery (When it’s to be done). Parties could be added for product managers and external suppliers (Who’s in charge).
Moreover, if systems are to support the continuity and consistency of business processes subject to market and organizational changes, product descriptions must be anchored to regulatory environments and intrinsic taxonomies.
