What is Data Cleaning?

What does Data Cleaning mean?

Data Cleaning (also called "data scrubbing" and "data cleansing") is the process of detecting, correcting, or removing errors, duplicates, and inconsistencies in datasets. In the context of MRO Data and ERP systems, data cleaning ensures that spare part catalogues, vendor information, and material records are accurate and reliable and connected to the plant hierarchy and functional locations.

For example, cleaning may involve fixing misspellings in material descriptions, removing duplicate spare parts, standardising units of measure, or updating obsolete supplier references.

Without systematic data cleaning, organisations risk downtime, inflated costs, and procurement inefficiencies due to unreliable information.

Key steps in Data Cleaning

  1. Duplicate removal – Identifying and merging duplicate part or supplier records.
  2. Error correction – Fixing wrong spellings, numbers, or formatting issues.
  3. Standardisation – Applying common rules for descriptions, codes, and units of measure.
  4. Validation – Ensuring fields are complete and consistent across systems.
  5. Enrichment – Adding missing technical or commercial attributes to make data more useful.

Why Data Cleaning is critical for asset-intensive industries

Clean data is the foundation for reliable ERP, CMMS, and EAM systems. Without it, companies face duplicate purchase orders, incorrect stock levels, and incomplete supplier information.

By applying structured data cleaning, organisations can:

  • Increase use of automated functions and shorten ordering processes
  • Enable data driven analytics and decision making
  • Improve spare parts availability for maintenance.
  • Reduce procurement errors and excess inventory.
  • Enhance supplier performance tracking.
  • Support ERP migrations and digital transformation initiatives.
