## Key Findings
|
||||
|
||||
### High-Impact Undocumented Areas
|
||||
|
||||
1. **Production Planning (60 tables, 80 use cases)**
|
||||
- Complete manufacturing workflow missing from documentation
|
||||
- Affects inventory, costing, and scheduling
|
||||
|
||||
2. **Asset Management (35 tables, 50 use cases)**
|
||||
- IT asset tracking infrastructure present but undocumented
|
||||
- Indicates MSP (Managed Service Provider) capabilities
|
||||
|
||||
3. **Data Exchange (40 tables, 60 use cases)**
|
||||
- EDI integration infrastructure present
|
||||
- Supplier data import automation (ALSO, Alltron, etc.)
|
||||
|
||||
4. **Quality Assurance (15 tables, 25 use cases)**

|
||||
|
||||
## Recommendations
|
||||
|
||||
### Priority 1: Document Production Features
|
||||
- Create comprehensive production planning module documentation
|
||||
- Map all 60 production tables to use cases
|
||||
- Document work order lifecycle
|
||||
- Define material consumption workflows
|
||||
|
||||
### Priority 2: Asset Management Documentation
|
||||
- Document IT asset tracking capabilities
|
||||
- Create device inventory use cases
|
||||
- Define patch management workflows
|
||||
- Add SNMP monitoring use cases
|
||||
|
||||
### Priority 3: Data Integration
|
||||
- Document EDI processing workflows
|
||||
- Create supplier data import use cases
|
||||
- Define duplicate detection rules
|
||||
- Add validation workflows
|
||||
|
||||
### Priority 4: Quality & Compliance
|
||||
- Document safety and compliance tracking

|
||||
|
||||
## Summary
|
||||
|
||||
**Discovered Undocumented Use Cases: ~450**
|
||||
**Coverage Gap: 82% of database schema**
|
||||
**Documentation Needed: Estimated 100-150 hours**
|
||||
|
||||
The c-entron.NET system has significantly more functionality than current documentation reflects. Critical business processes (production, asset management, data integration) are completely absent from USE_CASES.md despite having 150+ supporting tables in the database schema.
