Enrichment Process

Workflow

Existing Data -> Matching -> Enrichment -> Validation -> Integration
      |              |            |             |            |
  CRM Export    Identification   Data       Quality      CRM Import
                               Retrieval    Check

1. Inventory Analysis

Check	Question
Data quality	How complete is the data?

2. Matching

Matching - assigning existing data to external sources - is critical:

Name only	Low (duplicates)

3. Enrichment

Approach	Description
Batch	Mass processing, periodic
Real-time	On demand, immediate enrichment
Hybrid	Combination of both

4. Validation

After enrichment, verification should be performed:

Completeness	All desired fields filled?

5. Integration

System	Integration
