Implementation Readiness & Deployment Assurance Checklist

The implementation checklist serves as a rigorous readiness framework designed to ensure that the canonical data model, associated metadata structures, and automated code-generation pipelines are deployed consistently and accurately across client environments.

It provides a structured, end-to-end view of all prerequisites—spanning source-system understanding, metadata preparation, data quality governance, lineage instrumentation, and automation configuration—required before initiating full-scale ETL development.

Given that the solution operates on an insert-only, metadata-driven architecture using a supported tech stack, this checklist acts as the formal validation mechanism that all upstream dependencies are understood, documented, and operational before code execution begins.

Checklist Item
Source system documentation collected and analyzed
All source entities and attributes identified
Interface Mapping Document created and reviewed
Data quality rules defined and documented
PII classification completed for every onboarded attribute (not just identified — fully classified with category, tokenization status, and exposure flag)
Business sign-off obtained on mappings
Metadata tables created (all 10+ tables)
All metadata tables populated with complete data
Metadata completeness validated (no referential integrity errors)
Code generator configured and tested
LDZ ingestion code generated
RDV transformation code generated
Data quality validation code generated
Lineage capture code generated
Job orchestration generated
Grandmaster DAG and dependent Master DAG orchestration validated through successful end-to-end execution
Target database platform validated (Oracle / SQL Server / Snowflake) and deployment prerequisites confirmed
Generated code reviewed for correctness
Sample data transformation tested
Data quality validations verified
Lineage capture verified
All documentation completed and version controlled
Team trained on generated code and processes
Ready to proceed to Phase 2 (ETL Development)
DATA QUALITY CHECKLIST (Out-of-Box Categories — definitions in Metadata Model: The Core Integration Layer)
Mandatory field checks configured in Interface document for each onboarded subject area
Datatype checks and referential integrity checks defined in Interface document per attribute
Duplicate handling strategy confirmed in ETL design (reject / quarantine / merge) for customer and campaign keys
Consent value validity confirmed — valid code set loaded, expiry date handling logic verified
Campaign date validity confirmed — start/end date logic and active campaign rules verified
Contact / response chronology validated — response datetime ≥ contact datetime per campaign-customer record
Audience resolution completeness confirmed — resolution status captured per record; unresolved records flagged or quarantined
Tokenization completeness validated — all PII-flagged attributes confirmed tokenized before LDZ load; pipeline gate in place
Aggregate reconciliation checks configured — 360 view counts and sums reconcile against RDV within defined tolerance
PII GOVERNANCE CHECKLIST (Expanded)
Tokenization status validated before LDZ/RDV load — no raw direct identifiers permitted in pipeline
No raw direct identifiers present in 360 views (Customer, Campaign, Flowchart)
Free-text fields reviewed and either excluded from CDM or controlled with documented justification
Consent attributes mapped and validated (source, effective date, status, channel-level precedence)
MaxAI-exposed views reviewed for PII leakage — confirmed no raw identifiers in AI serving layer
Aggregation thresholds applied where needed to prevent re-identification from small cohorts
Audience resolution does not expose raw account/device/customer identifiers in downstream 360 views
Rejected attributes documented with reason and client sign-off obtained for approved CDM attribute exposure
PII matrix template completed and linked to implementation interface document (see Appendix)
Campaign AI Checklist
Flowchart 360 aggregation tables verified and data populated correctly
Flowchart 360 key attributes indexed (flowchart_id, campaign_code, execution timestamps)
Flowchart 360 pre-aggregated metrics validated (clicks, opens, responses per execution)
Multi Audience Support Checklist
Audience_map table populated and validated for all audience levels (customer / account / device)
Bridge table verified for Campaign → Offer → Channel → Product combinations

Audience resolution logic tested for multi-grain campaign execution scenarios

ML Feature Checklist
ML feature views (point-in-time consistent) created and validated from Customer 360
STO and NBC model output ingestion layer configured and tested

ML prediction write-back to Customer 360 verified (NBC / STO attributes populated correctly)

Incremental watermark-driven processing confirmed for ML feature refresh cycles
