Until now, much of the methodology and technology in the Master Data Management (MDM) world has been about how to optimize the use of what can be called first party master data. This is master data already collected within your organization and the approaches to MDM and the MDM solutions offered has revolved around federating internal silos and obtain a single source of truth within the corporate walls.
Besides that third-party data has been around for many years as described in the post Third-Party Data and MDM. Use of third party data in MDM has mainly been about enriching customer and supplier master data from business directories and in some degree utilizing standardized pools of product data in various solutions.
Using third party data for customer and supplier master data seems to be a very good idea as exemplified in the post Using a Business Entity Identifier from Day One. This is because customer and supplier master looks pretty much the same to every organization. With product master data this is not case and that is why third party sources for product master data may not be fully effective.
Second party data is data you get directly from the external source. With customer and supplier master data we see that approach in self-registration services. My recommendation is to combine self-registration and third party data in customer and supplier on-boarding processes. With product master data I think leaning mostly to second party connections in business ecosystems seems like the best way forward. There is more on that in a discussion on the LinkedIn MDM – Master Data Management Group.
