Sunsetting a Legacy Master Data Management System

IT Program & Project Management



National Retail Company


A national retail company was incurring cost increases due to duplicate customer records in their Marketing Cloud, while also supporting a legacy Master Data Management (MDM) system. The company was embarking on a strategy to sunset the current MDM and move to a more scalable, flexible and leading-edge solution and related technologies.


Leveraging its in-depth experience in Master Data Management, Pepper Foster worked closely with internal sponsors and stakeholders to assess the current state, identify and design a comprehensive solution that leveraged existing platforms and technologies, and achieve buy-in and approval.  In addition to driving the solution design, Pepper Foster also identified and assessed third party vendors to add value and augment existing infrastructure and worked across functional groups on project planning, implementation (Agile) and communications.


The team was able to:

- Merge approximately 1 million duplicate records using a third party vendor application

- Define/optimize processes that will identify and merge duplicate records in real-time going forward

- Migrate data associated with 13 million customers and 30 million assets from their legacy MDM to the new application platform

- Design and implement a leading-edge event driven bridge solution for ongoing data management
