High-Level Metrics
U.S. Tier-1 Carrier: Legacy MPLS to SD-WAN Migration
The Challenge
101,760+ circuits across 50 states requiring migration
28% rework rate causing project delays
Internal team at capacity, unable to scale
Vendor lock-in with unpredictable T&M costs
Our Approach
Deployed Circuit Migration Factory with fixed unit pricing
Pre-validated runbooks eliminated configuration drift
Weekly risk reviews with CAB-ready documentation
Surge capacity during peak migration windows
Outcomes
"Mikkena Global consistently delivered high-quality work with strong responsiveness and professionalism. Their approach added measurable value to our projects, particularly in strengthening our documentation and management systems."
North American MSO: Network Design & Engineering Transformation
The Challenge
91,031+ network designs required without standardized design frameworks
8.5-hour average restoration time driven by design rework
45% annual engineering attrition from constant firefighting
0 unified design validation model across builds and migrations
Our Approach
Design & Engineering-as-a-Service deployed at production scale
Canonical design frameworks implemented across the network lifecycle
85% fewer post-deployment fixes via enforced design standards
L1–L3 engineering ownership operationalized, escalation by exception
