What is Master Data Management?

Master Data Management is the discipline of creating and maintaining a single, authoritative, and consistent source of truth for an organisation's most critical shared data, such as customer records, product information, supplier details, and financial reference data. It ensures that every department and system across the business works with the same accurate information.

What is Master Data Management?

Master Data Management (MDM) is a comprehensive approach to defining, unifying, and managing the core data entities that are shared across an organisation. These core entities, known as master data, typically include customers, products, suppliers, employees, locations, and financial accounts. Unlike transactional data, which records individual events like a sale or a shipment, master data represents the fundamental business objects that those transactions reference.

The problem MDM solves is straightforward but pervasive: in most organisations, the same customer, product, or supplier exists in multiple systems with slightly different information. A customer might be "PT Maju Bersama" in the CRM, "Maju Bersama Pte Ltd" in the accounting system, and "Maju Bersama" in the e-commerce platform. Without MDM, each system treats these as different entities, leading to fragmented reporting, duplicated communications, and poor decision-making.

How Master Data Management Works

MDM involves several key processes and capabilities:

  • Data consolidation: Bringing together records from all source systems into a central repository where duplicates can be identified and resolved.
  • Data matching and deduplication: Using algorithms to identify records that refer to the same real-world entity, even when names, addresses, or identifiers differ slightly.
  • Golden record creation: Establishing a single "golden record" for each entity that represents the most complete and accurate version of the data, assembled from the best information available across all sources.
  • Data stewardship: Assigning ownership and accountability for data quality to specific individuals or teams who review and approve changes to master data.
  • Synchronisation: Distributing the authoritative master data back to all consuming systems so that every application works with the same information.
  • Governance policies: Defining rules for how master data is created, updated, archived, and accessed across the organisation.

MDM Implementation Styles

There are several architectural approaches to MDM, each with different trade-offs:

  • Registry style: A central index links records across systems without physically consolidating the data. Fastest to implement but provides less control over data quality.
  • Consolidation style: Data is copied from source systems into a central hub for cleansing and matching, but the hub does not write back to sources. Good for analytics and reporting use cases.
  • Coexistence style: The central hub and source systems both maintain and update master data, with synchronisation keeping them aligned. Balances control with flexibility.
  • Centralised style: All master data creation and updates happen through the MDM hub, which is the single authoritative source. Provides the strongest data quality but requires the most organisational change.

Master Data Management in the Southeast Asian Context

For businesses operating across multiple ASEAN markets, MDM addresses challenges that are particularly acute in the region:

  • Multi-entity consolidation: Companies with subsidiaries or operations in Singapore, Malaysia, Indonesia, Thailand, and other markets often maintain separate systems per country. MDM creates a unified view across all entities.
  • Character set and language variations: Customer and product names may appear in Latin, Thai, Chinese, or other scripts across different systems. MDM tools can handle cross-script matching and standardisation.
  • Regulatory compliance: Data protection laws across ASEAN, including Singapore's PDPA, Thailand's PDPA, and Indonesia's PDP Law, require organisations to know exactly what personal data they hold and where. MDM provides this visibility.
  • Merger and acquisition support: As ASEAN markets continue to see significant M&A activity, MDM is essential for integrating the data assets of acquired companies.

Getting Started with Master Data Management

  1. Identify your most critical master data domain: For most businesses, this is either customer data or product data. Start with whichever domain causes the most pain today.
  2. Audit existing data quality: Understand the scale of duplication, inconsistency, and incompleteness before selecting tools or designing processes.
  3. Establish data ownership: Assign clear accountability for each master data domain. Without stewardship, data quality improvements are temporary.
  4. Choose the right implementation style: Registry or consolidation approaches are faster to implement and suitable for organisations beginning their MDM journey.
  5. Invest in change management: MDM requires people to change how they create and manage data. Training and communication are as important as the technology.
Why It Matters for Business

Master Data Management is a foundational capability that affects virtually every aspect of business operations. When master data is inconsistent, the consequences ripple through the entire organisation: sales teams contact the same customer multiple times, finance cannot reconcile figures across subsidiaries, marketing campaigns are sent to duplicate addresses, and management reports present conflicting numbers.

For companies in Southeast Asia managing operations across multiple markets, the problem is amplified. Each country operation may have introduced its own systems and data standards, creating silos that make consolidated reporting and cross-market analytics extremely difficult.

The business case for MDM is both defensive and offensive. Defensively, it reduces errors, eliminates wasted effort on duplicate records, and ensures regulatory compliance. Offensively, it enables a unified view of customers that powers better personalisation, cross-selling, and customer retention. Organisations with mature MDM capabilities consistently make faster, more confident decisions because they trust the data underpinning those decisions.

Key Considerations
  • MDM is as much an organisational challenge as a technical one. Success requires executive sponsorship, clear data ownership, and willingness to standardise processes across departments.
  • Start with one master data domain rather than trying to manage all domains simultaneously. Customer MDM or product MDM are the most common starting points.
  • Data quality is a journey, not a destination. Establish ongoing processes for data stewardship and quality monitoring rather than treating MDM as a one-time cleanup project.
  • Cloud-based MDM solutions from vendors like Informatica, Reltio, and Profisee have reduced implementation timelines and costs, making MDM accessible to mid-sized organisations.
  • Plan for data governance alongside MDM. Without clear policies on who can create, modify, and approve master data, quality will degrade over time.
  • In multi-market ASEAN operations, pay particular attention to name matching across languages and scripts. Standard deduplication rules designed for English-language data often perform poorly with Thai, Vietnamese, or Chinese names.

Frequently Asked Questions

What is the difference between master data and transactional data?

Master data describes the core business entities that remain relatively stable over time, such as customers, products, suppliers, and locations. Transactional data records individual business events, like a purchase order, a payment, or a shipment. Transactions reference master data: a sales transaction links to a customer record and a product record. MDM focuses on ensuring those referenced entities are accurate and consistent.

How long does an MDM implementation typically take?

A focused MDM initiative for a single data domain, such as customer data, typically takes three to six months for initial deployment. More comprehensive programmes spanning multiple domains and integrating with many source systems can take twelve to eighteen months. The timeline depends heavily on data complexity, the number of source systems, and organisational readiness to adopt new data management processes.

More Questions

Yes, particularly if data quality issues are already causing visible problems such as duplicate customer communications, inconsistent reporting, or difficulty consolidating data across markets. Cloud-based MDM platforms have significantly lowered the entry point. For SMBs, starting with a focused scope, such as deduplicating customer records, can deliver measurable ROI within months and build the foundation for broader MDM capabilities over time.
