MDM (Master Data Management)
MDM is the discipline that keeps a single trusted record for every customer, supplier, material and service in the company. It brings registration, quality rules, approval and distribution into one process, so every system reads the same version of the data — not five similar ones.
In practice
What this changes in your master data
It is not a new ERP field
MDM is a process with an owner, a rule and an audit trail. The system supports the process; it does not replace the decision about who may register what.
Start with the domain that hurts
Supplier, material, customer or service: closing the cycle on one domain delivers value before the whole programme finishes.

In practice, MDM decides who may create a record, what must be filled in for it to be valid, who approves it, and how the information reaches the ERP and the other systems. Without that, each area creates its own record and the divergence shows up in purchasing, invoicing and inventory.
MDM is the whole discipline — people, process and technology. MDG (Master Data Governance) is the part that defines and enforces the rules: who approves, what is mandatory, what blocks. In practice you hear both terms for the same programme.
No. MDM works alongside the ERP: the record is created and approved in the governed flow and reaches the ERP already valid. Replacing an ERP is a decision of another order.
It depends on the domain and on the current state of the data. The lower-risk path is to close the cycle on one domain first, with a measured result, before scaling. [VERIFICAR: typical timeline per domain, based on delivered projects]
