What kind of essential product information does a PDM system use?
Its organisational usefulness is not so much focused on product sales specifications (such as measurements, sizes, colours, prices...) as on other aspects that are very important in the manufacturing process and which guarantee perfect and regulated products: safety tests, permits and approvals, patents, record of manufacturing sites for each product or batch, distribution channels to which a product or collection is launched...
Can a PDM system help me in the creation of product catalogues, websites and e-commerce applications?
Not in a specific way. A Product Data Management system is key in other phases of the product life cycle, especially manufacturing. For example, if a product released to the market turns out to be defective, thanks to Data Management technology, it is possible to locate the origin of the error, update it and send the new instructions to the manufacturing process.
