What's your issue?

23.
Tips:
l. Confirm and Re-confirm that you have the right model
Version
Edition
Status
2. Confirm and Re—confirm you have all the parts, notjust the diagrams
3. A model file is only a small part ofa modeling project. Find all the parts.
4. Copy. Backup. Publish.
Model
Model Reports
Comparison Reports
Findings/ Observations

24.
5. Start publishing Issues. Without blame.
Gaps/ Overlaps
Compliance with internal standards
Fit to databases/ datastores
6. Version Control — use it.
Repository/ l/ lodel l/ lart
Other team versioning
7. Monitor for data models outside accepted processes
Team Drives
Repository
Sharepoint
Other shared resources
