Duplication is a very common issue within all organisations that manage data, regardless of their size or industry, and can drastically affect data quality. Records can be duplicated one or many times, and can vary greatly while still sharing some common information; for example, the same name, address, company, phone number or email address. The de-duplication process involves not only identifying and removing repeated records, but also ensuring pre-determined business rules are followed and additional information captured.
Common reasons for duplicate records are:
- Poor practices for collecting and entering data.
- Poor management and maintenance of data.
- Insufficient funds, attention and training given to data governance within an organisation.
Data quality is very important: estimates suggest poor quality data can cost an organisation 10-20% of annual revenue in lost sales, ineffective direct marketing, administration overheads and preventable shipping errors. If not addressed regularly, data duplication can impact on all data-driven activities, especially marketing campaigns and results.
