PIM vs. MDM: What’s the Difference and Which Do You Need?

PIM and MDM Are Not the Same Thing
Organizations that start researching PIM often run into MDM along the way, and the two are frequently treated as one and the same. It’s an easy mistake, since both deal with information that needs to be managed across different systems. The difference is in what each is designed to handle and how that information is used.
PIM (product information management) focuses on collecting, organizing and enriching the information used to describe products. This includes descriptions, specifications, images and other details that sales, marketing and customer service teams rely on. MDM (master data management) takes a broader approach. It manages important business records, which can include products, customers, suppliers and locations, with the goal of keeping that information accurate and consistent across the systems that use it.
Where PIM Fits
A PIM is where product information gets prepared before it goes anywhere else. It can pull in details from the ERP, supplier data and other sources, so someone can look over what’s there, fill in what’s missing and get everything into the same format. The review step being the most important, since, incoming data isn’t always right. One apparel retailer, for example, found it was receiving a “heel height” attribute on sweaters.
Then there’s the question of where the information is headed. Trading partners can have requirements of their own, and some attributes are specific to a partner and set out in trading partner agreements. Without a PIM, teams can end up saving their own versions of the data; the better approach is to work from a single source, and a PIM can handle mass updates and custom exports from it, so content is managed in one place and adjusted for each channel. That cuts down on the manual work of keeping everything current, though it doesn’t remove it entirely.
Where MDM Goes Further
MDM is less about preparing content and more about keeping business data consistent. Information gets entered and updated in all kinds of applications, and those applications don’t always follow the same rules. A common version of this is different departments keeping separate records of the same customer, which leads to inconsistencies and inefficiencies. MDM sets out how records are maintained and how changes are handled, so different departments and systems are working from information that matches.
It also deals with how records connect to each other. When the same customer shows up differently in separate systems because of typos or formatting differences, MDM tools can standardize the data and merge the duplicates into a single profile. Over time, that work extends to sorting out conflicts and improving the quality of the data.
The easiest way to separate the two is by what each one is focused on. A PIM concentrates on getting product content ready for the channels that use it, while MDM looks at the wider set of relationships behind the business. They aren’t competing. MDM can help govern the core product records, and a PIM can handle the extra content needed to present and distribute those products.
How They Work Alongside the ERP
Neither PIM nor MDM is intended to replace an ERP. The ERP still handles important operational processes such as orders, inventory, purchasing and accounting. PIM and MDM work alongside it, addressing different aspects of the information those processes use.
A PIM takes product details from the ERP, add descriptions, images and specifications, then distribute the finished content to website, ecommerce platforms and other channels. An example of this is a large retailer using a PIM as the single source of truth for everyone downstream, with integration to internal and external data sources. In another, a healthcare provider built data cleansing and consolidation into its new PIM rollout so the system started with good-quality data, with a centralized team managing new items afterward.
MDM can work across several systems to maintain trusted product, customer and supplier records. Pearson, the educational publisher, spent four years bringing a mix of ERP and CRM applications, many inherited through acquisitions, under a master data management system that became the authority for customer and product data. Before that, systems that didn’t agree on details could treat one customer as several, for instance by listing the same university under two different names, and the mismatched data was causing interfaces in the ERP environment to fail.
Which One Do You Need?
The answer depends on the information you’re trying to manage and where the problems are occurring. If the main challenge is incomplete product descriptions, missing specifications or maintaining product content across several channels, PIM may be the right place to start. If inconsistencies extend to customer, supplier and product records across multiple business systems, the organization may need a broader MDM approach. It’s not necessarily an either-or decision. Some businesses need one, while others benefit from using both.
