Material masters are the largest and most complex of all master data types. In most manufacturing and asset-intensive organisations, material master data has been entered by dozens of individuals, over decades, to a variety of short-hands and standards, and with little governance. Data has accumulated both through everyday operating activities as well as mergers and acquisitions. End-users, manufacturing, purchasing, engineering and finance share the resultant common data challenges of duplication, inconsistent, inaccurate and incomplete descriptions. Often, small in-house data-cleaning projects have attempted to alleviate the problems. Infoplus MDM data cleaning solutions provide a stable long-term cure. Our implementations utilise leading software, are based on international standards and our market-leading technical dictionary, leverage our structured vendor reference catalogue, follow consistent processes and are delivered by a large team of experienced professionals. The outputs of the project are corporate-wide dictionary standards, consistent and compliant descriptions, and duplicate elimination. In other words, golden materials data. This enables efficient searching, improved asset utilisation and enhanced procurement activities.
