The core of DSVC begins with the fully customized Design module that integrates model specifications to determine real-time costs and weights for each item and each possible variant of that item. A unique speaking number details every component necessary for production and pricing: metal, colored stone, diamond, labor, and accessories. This information is also used to automatically generate a BOM and create purchase requisitions for components in shortage. Additionally, standard routing information is recorded in this module for use by production planners and sales managers.
