Both models are viable at scale — the right choice depends on change classification, regulatory exposure, and organizational maturity rather than site count alone.
Architectural Trade-offs
| Criteria |
Centralized |
Distributed |
| Approval latency |
High (your 2-week figure is typical) |
Low (hours to days) |
| Decision consistency |
High |
Variable without strong governance guardrails |
| Audit trail uniformity |
Straightforward |
Requires explicit policy enforcement per node |
| Bottleneck risk |
Systemic — single board is a chokepoint |
Localized — failures don’t cascade |
| ENOVIA config complexity |
Lower (one route policy, one approval group) |
Higher (route templates per region/function, delegation rules) |
| Regulatory compliance |
Easier to demonstrate |
Requires documented delegation authority |
| Scalability at 800+ engineers |
Degrades under volume |
Scales horizontally if governance layer is solid |
What Most Large Deployments Actually Do
Pure centralized or pure distributed are both edge cases. At your scale, a tiered hybrid model is the dominant pattern:
- Change classification drives routing — define impact tiers (e.g., Safety/Regulatory, Major, Minor, Administrative) in your Change Order or ECO type configuration
- High-impact changes escalate to the central board; lower-impact changes route to functional or regional approvers
- The central board becomes a ratification body for pre-vetted complex changes rather than a first-pass filter
In ENOVIA, this maps to route templates with conditional branching based on attribute values (severity, affected commodity, site of origin). The Policy object controls state transitions; you can gate promotion to Approved state on a dynamic approver list resolved at runtime (verify in your version — route template capabilities vary between 3DExperience releases).
Specific ENOVIA Configuration Considerations
ECO Type → Attribute: "Change_Tier" (range: Safety, Major, Minor, Admin)
Route Template: IF Change_Tier == "Safety" → Central Board group
IF Change_Tier == "Major" → Regional Lead + Central Board review
IF Change_Tier == "Minor" → Functional Approver only
IF Change_Tier == "Admin" → Auto-approve or single approver
Delegation rules and escalation timeouts are critical for distributed nodes — without enforced SLA escalation back to a parent approver, latency just shifts location rather than decreasing.
Compliance Angle
For ISO 9001 or AS9100 environments, distributed approval is defensible provided your delegation authority is documented, approvers are trained and qualified per your QMS, and ENOVIA captures the actual decision maker (not just the routing group). Audit queries hit the History and Route objects — ensure your schema retains approver identity at each node.
Your 2-week latency is a process problem, not purely an architecture problem — meeting cadence and quorum rules are the real constraint, not centralization itself.
Ultimately, this depends on context / your requirements: change volume, regulatory regime, and how much governance infrastructure you can maintain at regional nodes.
