MDM: unique, reliable data shared across the entire IT system

Customers, products, suppliers, business repositories… reference data is at the heart of operational processes.

Without a structured MDM approach, it quickly becomes:

Inconsistent,
Duplicated,
A source of operational errors and biased reporting.

At Netsystem, we support companies in implementing pragmatic, operational MDM approaches tailored to their IT environment.

What is third-party data?

Third-party data includes all information describing external entities with which the company has a relationship.

It covers in particular:

Prospects, for business generation,
Customers, for invoicing, follow-up and commercial relations,
Suppliers and subcontractors, for purchasing, compliance and risk management.

This data includes:

Legal and administrative information,
Operational and contractual data,
Compliance, solvency, liability and risk information.

What are the criteria for high-quality data?

Accuracy
Completeness
Timeliness
Integration

A recurring observation among our customers

Multiple versions of the same data
Variable quality depending on the application
Conflicts between ERP, CRM and business tools
Difficulty in ensuring the reliability of key indicators
Operational and regulatory risks

MDM becomes essential as soon as the IS becomes more complex.

The challenges of an MDM approach

An MDM approach enables you to:

Guarantee a single source of truth,
Improve data quality and reliability,
Secure critical processes (invoicing, purchasing, reporting),
Support ERP, BI and AI projects,
Facilitate external growth and carve-out operations.

MDM in data governance

MDM is not just a technical tool. It is part of a comprehensive data governance approach:

Management rules defined upstream,
Clearly established responsibilities,
Controlled usage,
Traceability and control of changes.

Effective MDM is always based on clear governance.
