The Customer 360 Promise

Every enterprise wants a single, complete, accurate view of their customers. Few achieve it. The gap between aspiration and reality is almost always a data quality problem.

Why Customer 360 Fails

Data Silos

Customer data lives across CRM, marketing automation, e-commerce, support systems, loyalty programs, and more. Each system has its own version of the customer.

Identity Resolution Challenges

The same customer appears as:

"John Smith" in CRM

"J. Smith" in the billing system

"johnny.smith@email.com" in marketing

A cookie ID in web analytics

Data Quality Issues

Incomplete profiles — many organizations report a majority of CRM records missing key fields

Outdated information — B2B contacts change jobs frequently, often cited at around 25% annually

Inconsistent formats across systems

Duplicate records inflating customer counts

MDM for Customer 360

Identity Resolution

MDM platforms provide the matching engine to resolve customer identities:

Multi-attribute matching across name, email, phone, address

Probabilistic scoring for fuzzy matches

Household and relationship linking

Cross-device identity stitching

Golden Record Creation

Survivorship rules create the best possible customer profile:

Most recent contact information

Most complete demographic data

Aggregated transaction history

Unified consent and preference management

Real-Time Updates

Modern MDM supports event-driven updates:

Customer interaction triggers profile refresh

Address change propagates across all systems

Consent update reflects immediately everywhere

Data Quality Foundation

Profile Completeness

Implement quality rules for customer data:

Minimum viable profile (name + email or phone)

Progressive enrichment strategy

Third-party data append for gaps

Contact Data Verification

Keep data current and accurate:

Email deliverability verification

Address standardization and validation

Phone number validation

Deceased and moved-away flagging

Ongoing Quality Monitoring

Quality scorecards by customer segment

Automated decay detection

Stewardship workflows for exceptions

Regular data quality audits

Business Impact

Organizations with effective Customer 360 report:

30% improvement in marketing campaign ROI

25% reduction in customer churn

20% increase in cross-sell/upsell revenue

40% faster customer service resolution

Significantly improved customer experience scores
