When you compare MDM-based product-content management and catalog publishing with common, solely DTP-based, catalog publication procedures, I see the key benefits of MDM as shown in the graphic below.
- The MDM way of publishing product data allows loading and consolidating product data from different sources.
- It provides a single source of truth, and assured product quality from the start.
- Data consolidation features (in terms of structure and content) are combined with automated product layouts at highest level of consistency across all content.
- Layout finalization steps are done in the DTP application.
This approach allows for maximum re-usability and is open to multi-channel publication (for example, Web catalogs).
In summary, the MDM approach brings big potential for reducing production cost and time compared to conventional catalog publication procedures. It is based on a complete quality loop which eliminates the risk of late error detection.
