| Content Files | Templates and families | Ensure consistency |
| Support Team | Technical help | Provide ongoing support |
| Training Materials | Learning resources | Build team skills |
| Administration | Oversight and updates | Maintain compliance |
"For the entire system, remember that one change in a subsystem impacts the overall system and often requires another change in a different subsystem." – Autodesk University [4]
Step 5: Test and Refine the BIM Process
Start small by running pilot projects to test your BIM implementation. This will help you:
- Spot and fix bottlenecks
- Adjust your standards
- Refine training programs
- Confirm resource allocation
- Measure performance improvements
Track performance metrics and gather feedback from your team to fine-tune your approach before rolling it out on larger projects.
