Three CRMs after two acquisitions: 1.4M customer records, maybe 30% overlap. Sales wants one customer view this quarter. Sequence?

CLAUDE · AS WILHELM, MASTER DATA MANAGEMENT SPECIALIST One quarter buys the customer domain with survivorship rules, not enterprise MDM. Sequence: profile all three sources first - fill rates, format drift, and dupes within each system; there are always dupes within before across. Then match in two tiers: deterministic on normalized email and phone, probabilistic with blocking keys on name plus address, thresholds tuned on a 500-pair labeled sample. Survivorship is field-level, not record-level - most-recent wins for phone, system-of-record wins for billing. And expect that 30% overlap estimate to be off by half in either direction. Which system does sales actually live in? That's your hub.

// what's inside

What you're actually buying

Senior Master Data Management Specialist who builds a field-level survivorship matrix instead of one record-level rule.

Wilhelm covers the full golden-record surface: designing a single source of truth for customer, product, or vendor data across systems, writing matching and deduplication rules, setting confidence thresholds and survivorship logic, choosing hub-and-spoke versus registry-style MDM tooling patterns, defining data domain ownership models, and designing sync and propagation strategy so golden-record updates reach source systems without creating update loops.

Who it's for

Data platform and MDM teams untangling the same customer, product, or vendor existing as slightly different records across systems, who need matching thresholds and survivorship rules backed by a measured false-merge rate, not a round number.

Key capabilities

Deterministic and probabilistic matching rules tested against a labeled sample before setting a threshold
Field-level survivorship matrix with explicit tie-breakers, never a single record-level "last write wins" rule
Hub-and-spoke vs registry-style MDM pattern chosen from how downstream systems actually consume the record
Domain ownership and escalation paths defined before the first cross-domain field dispute
Sync-back designs with provenance tagging so a golden-record update doesn't loop back and reprocess itself

Questions about this product

What AI tools does this work with?+

Claude, ChatGPT, or any AI chat that accepts a system prompt or project instructions. Claude Projects gives the best results.

How do I install it?+

Paste the SKILL.md content into your Claude Project Instructions or your AI's system prompt. Under 2 minutes, no setup required.

Is this a course or a tool?+

It's a skill file, not a course. One file that turns your AI into a configured Master Data Management (MDM) Specialist ready to work on your Master Data Management (MDM) Specialist problem immediately.

Our golden record keeps reverting to stale data, what does Wilhelm check?+

He checks whether survivorship is being applied per record instead of per field, since treating a low-quality source as equally authoritative for every field is exactly how a fresher fact from a trusted source gets silently overwritten by a stale one.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
